When we talk about fire door safety, most people think about whether a door can withstand fire for a certain period. That is certainly important, but there is another issue that deserves just as much attention: can the door help limit the spread of smoke? In a real fire, smoke can move through gaps around a door, between the door leaf and its frame, or through poorly sealed installation joints. These small gaps may seem harmless during normal use, yet they can make a real difference in an emergency.

At Guangzhou Chuangge Automation Equipment Co., Ltd., we understand that manufacturers and testing laboratories need more than a machine that simply runs a test. They need testing equipment that matches the dimensions of their products, follows the correct test method, records useful data, and supports repeatable testing. Our CG2902 Smoke-Control Performance Test Apparatus for Large-Scale Fire Doors is intended for this type of testing application, helping users evaluate the smoke-control performance of large-scale fire door assemblies under defined conditions.

We specialize in customized testing equipment for construction materials and components, wires and cables, plastics and textiles, electrical accessories, electronic products, and home appliances. For a smoke-control Performance Test Apparatus, we focus on understanding the customer's testing objective before discussing the equipment configuration. Door dimensions, test temperatures, differential pressure requirements, airflow measurement, specimen installation, data recording, and the applicable standard can all influence the final design.

This page explains the purpose of the CG2902 Smoke-Control Performance Test Apparatus, the basic principles behind smoke leakage testing, the main factors to consider when selecting a system, and the practical details involved in customization and delivery. We also explain the relevant standards so that buyers can make a more informed decision instead of choosing equipment based on its name alone.

1. What Is the CG2902 Smoke-Control Performance Test Apparatus?

Understanding the purpose of smoke-control testing

A fire door is part of a building's fire protection system. Depending on its design and intended application, it may help separate different areas of a building, restrict the movement of smoke, or provide a barrier during a fire. However, the performance of a complete door assembly depends on more than the door leaf itself. The frame, hinges, closing mechanism, seals, hardware, installation gaps, and surrounding construction can all affect the result.

Our CG2902 Smoke-Control Performance Test Apparatus for Large-Scale Fire Doors is designed around the need to assess smoke-control performance through a controlled testing process. In a typical smoke leakage test, a door assembly is installed in a test opening, a pressure difference is established between the two sides, and the airflow passing through the assembly is measured. Depending on the selected test method, the procedure may also involve specified air-temperature conditions.

The basic idea is easy to understand. If the pressure on one side of a closed door is higher than the pressure on the other, air tends to move through any available leakage paths. By measuring the airflow under controlled conditions, a laboratory can assess how effectively the tested assembly restricts air movement through its gaps. The measured result can then be evaluated according to the applicable standard or project requirements.

It is important to distinguish smoke leakage testing from a Fire Resistance Test. A smoke-control performance test apparatus is used to evaluate leakage under defined test conditions. A fire resistance test, by contrast, evaluates specified performance criteria under a fire exposure. These tests address related but different aspects of fire safety, and one test cannot automatically replace the other.

Why large-scale fire doors require careful equipment planning

Large-scale fire doors can create practical challenges for a testing laboratory. A larger specimen may require a larger test opening, stronger supporting structures, appropriate sealing arrangements, and enough working space for safe installation. The weight and dimensions of the door may also affect how the specimen is handled and secured.

For this reason, we recommend discussing the actual specimen before finalizing the equipment design. A customer who mainly tests one standard door size may need a different arrangement from a laboratory that evaluates several door widths, heights, frame types, or opening configurations. If the system is expected to test sliding doors, rolling shutters, glazed door assemblies, or other special designs, these details should also be reviewed during the technical discussion.

The CG2902 name identifies the product model supplied for this application. The exact test capacity, operating temperature range, pressure range, measurement accuracy, control functions, and supported specimen dimensions must be confirmed against the final technical specification. We do not recommend assuming that every possible function is included in a standard configuration without checking the agreed scope.

Who may need this equipment?

The equipment may be relevant to fire door manufacturers, building-material testing laboratories, independent inspection organizations, research institutions, and companies developing smoke-control door systems. Manufacturers can use test results during product development and quality checks. Laboratories may need a more controlled process for carrying out customer projects. Research teams may use measured leakage data to study how different seals, frames, installation details, and door constructions affect airflow.

For each application, the testing objective should be clear before the machine is ordered. Are you comparing two sealing designs? Evaluating a new door assembly? Establishing a routine laboratory test? Or preparing equipment for a specific certification project? These questions help us determine what the system needs to do and which features are genuinely useful.

2. How Does a Smoke-Control Performance Test Work?

The principle: controlled pressure and measured airflow

The central principle of smoke leakage testing is to create defined conditions on both sides of a closed door assembly and measure the airflow that passes through it. The pressure difference is often called differential pressure. In simple terms, it describes how much the air pressure on one side differs from the pressure on the other side.

When a door is closed, air may still pass through small openings around the door leaf, frame, seals, or other parts of the assembly. A test system establishes the required pressure conditions and measures the resulting airflow. When the test procedure requires different pressure levels, the system must be capable of supporting the relevant test sequence and recording the associated measurements.

Temperature may also be part of the test. Cold-smoke or ambient-temperature testing and medium-temperature testing are not identical procedures. The equipment must be configured to match the required conditions rather than treating all smoke-control tests as the same operation.

For example, ISO 5925:2025 covers ambient-temperature and medium-temperature leakage tests for smoke-control door and shutter assemblies, as well as certain self-closing glazed elements. It describes determining leakage under specified conditions. The standard does not itself establish acceptable leakage limits for every application; those limits depend on the relevant regulations or requirements. Buyers should therefore identify both the test method and the acceptance criteria that apply to their project.

A practical testing workflow

Although the exact sequence depends on the selected standard and the final equipment configuration, a typical project can be understood through the following stages.

1. Review the test requirements. We confirm the applicable standard, specimen type, dimensions, temperature conditions, pressure levels, measurement requirements, and reporting needs with the customer.

2. Prepare the specimen. The door assembly is checked for identification, dimensions, construction details, seals, hardware, and other relevant features. Preparation must follow the selected test method.

3. Install the assembly. The specimen is mounted in the designated supporting or associated construction. The installation and sealing arrangements must reflect the test requirements and the intended scope of evaluation.

4. Check the measuring system. The pressure, temperature, and airflow measurement equipment required for the test is installed and checked. Measurement equipment should be suitable for the expected operating conditions.

5. Establish the test conditions. The system is operated to achieve the specified conditions. This may include a defined differential pressure and, where required, a specified temperature condition.

6. Record the measurements. Airflow and other required parameters are recorded according to the test procedure. The operator should also note observations that may affect the interpretation of the results.

7. Review and report the results. The recorded values are processed and reported in the format required by the applicable procedure. Acceptance is determined against the relevant limits, not simply by whether the equipment completed the test.

This workflow is a general explanation, not a replacement for the complete test standard. The exact sequence, number of test conditions, stabilization requirements, calculations, and reporting format must be confirmed for the intended application. During customization, we use these requirements to define the appropriate equipment functions and operating procedures.

What does the test result tell the user?

A leakage result provides information about the amount of airflow passing through the tested door assembly under the stated conditions. It can help users compare designs, investigate possible leakage paths, and assess whether a specimen meets a specified requirement.

However, the result must be interpreted carefully. Leakage values obtained at different pressure differences, temperatures, specimen sizes, or installation conditions may not be directly comparable. A report should identify the conditions under which the measurement was taken. Otherwise, a number on its own can be misleading.

We encourage customers to treat the test report as a complete record rather than a single result. Specimen identification, installation details, test conditions, measurement data, and relevant observations all help make the result more useful for engineering decisions and future quality checks.

3. Main Equipment Features and Technical Considerations

Configuration for large specimens

For a large-scale fire door smoke leakage testing system, specimen size is one of the first points we review. The supporting frame and test opening must accommodate the intended door assembly while providing the structural stability needed during testing. The design also needs to allow practical access for specimen installation, inspection, and removal.

When a customer tests several door sizes, we review whether a single configuration can support the required range or whether different fixtures or supporting arrangements are needed. A system designed around one specimen should not be assumed to accommodate every other design. Door height, width, thickness, opening method, frame construction, and mounting details may all affect compatibility.

Differential pressure control and monitoring

Differential pressure is central to a smoke-control performance test. If the pressure condition is incorrect or unstable, the resulting airflow measurement may not represent the intended test condition. For that reason, the pressure-control and monitoring arrangement must be selected according to the applicable procedure and the customer's required operating range.

During the design stage, we discuss the target pressure levels, the way pressure is generated, the monitoring method, and the requirements for recording the measured values. Where a test procedure specifies multiple pressure conditions, the system arrangement must support the required sequence. The final pressure range and control performance should be stated in the approved technical documentation rather than assumed from a general product description.

Airflow measurement and useful data

Airflow measurement helps determine the leakage rate through the tested assembly. The measurement method, instrument range, resolution, installation arrangement, and data processing all influence the usefulness of the results. The appropriate configuration depends on the expected leakage level and the measurement requirements of the selected standard.

We recommend confirming whether the customer needs manual recording, digital data collection, automatic calculations, exported test records, or other software functions. These requirements should be discussed before the order is finalized. If the laboratory already uses a particular reporting format, sharing a sample report can help us understand the expected data structure.

Automatic data recording can reduce repetitive manual work, but it does not remove the need for correct specimen installation, instrument checks, or trained operators. Reliable testing comes from the complete process, including the machine, the measurement system, the test procedure, and the people carrying it out.

Temperature-related requirements

Some smoke leakage methods involve ambient-temperature conditions, while others require medium-temperature testing. These conditions can affect equipment design, temperature measurement, insulation, safety measures, and operating procedures. A system intended for ambient-temperature testing should not automatically be considered suitable for medium-temperature testing.

When a customer needs temperature-related functions, we first identify the relevant test method and its stated requirements. We then review the required temperature range, measurement points, stabilization process, protective arrangements, and operating sequence. Any heating system, temperature-control function, or associated safety feature must be included in the final confirmed configuration if it is required by the project.

Operator access and day-to-day operation

A testing machine should be practical to use, especially in a laboratory where specimens may be tested repeatedly. Access to the mounting area, the position of measuring instruments, the visibility of operating information, and the ability to inspect seals and fixtures can all affect daily work.

We therefore consider how operators will install specimens, check connections, monitor the process, and retrieve test records. Where applicable, the design discussion can cover control interfaces, operating prompts, emergency stopping arrangements, guarding, and maintenance access. The exact features depend on the final design and should be confirmed before production.

Our goal is not to add functions simply to make a specification look longer. We aim to match the system to the actual test task, so the customer receives equipment that supports the required work without unnecessary complexity.

Comparison table: key system functions to confirm

The following table is a project-planning guide based on the measurement topics identified in ISO 5925:2025. It is not a claim that every function is included in every CG2902 configuration. The final scope should be agreed with the customer and checked against the full standard.

Reference: ISO 5925:2025, Smoke-control door, shutter assemblies and self-closing glazed elements — Ambient-temperature and medium-temperature leakage tests. The standard's public contents identify differential pressure, air temperature, airflow, specimen preparation, test procedures, observations, and reporting as relevant topics.

4. Applicable Standards, Test Planning, and Result Interpretation

Why the standard must be selected before the equipment is finalized

When purchasing fire door testing equipment, it is tempting to begin with machine dimensions and a price quotation. In practice, we believe the applicable test method should come first. Different standards may define different specimen arrangements, test conditions, measurement procedures, and reporting requirements. If these points are not identified early, the customer may discover later that the equipment configuration does not match the intended laboratory work.

For smoke-control door assemblies, ISO 5925:2025 is an important international reference. Its scope covers leakage tests at ambient and medium temperatures for door and shutter assemblies, as well as specified self-closing glazed elements. The document describes the determination of leakage under defined conditions. It also makes clear that acceptable leakage rates are established by the regulations or authorities controlling the particular application, rather than by the test method alone.

For projects in Europe or other markets that use regional standards, customers may also need to review the applicable edition of EN 1634-3 or the relevant national adoption. The exact standard and edition should be confirmed with the testing laboratory, certification body, or authority responsible for the project. A draft revision, a published standard, and a locally adopted edition should not be treated as interchangeable.

We do not assume that a reference to one standard automatically proves conformity with every other standard. Before confirming a quotation, we recommend checking the full document, including its specimen requirements, measurement clauses, operating conditions, calculations, and reporting requirements.

Standards comparison table

The table below provides a high-level guide to selecting a standards reference. It is intended to support the initial technical discussion, not to replace a formal standards review.

Sources: The official ISO page for ISO 5925:2025 and the standards information page for the EN 1634-3 revision project. The EN reference must be checked against the exact edition adopted for the intended market before the equipment specification is approved.

Equipment capability is not the same as product certification

This distinction matters for both equipment buyers and fire door manufacturers. A test apparatus creates the conditions needed to carry out a test and measure relevant values. A test report documents the results. Certification, classification, or approval may involve additional requirements, independent review, product documentation, and formal procedures established by the responsible organization.

For example, a laboratory may use a smoke-control performance test apparatus to measure leakage from a particular door assembly. Whether the door meets the required limit depends on the applicable acceptance criteria and the result obtained under the prescribed conditions. Whether a certificate can be issued depends on the applicable certification process. Purchasing the machine alone does not automatically certify a product or a laboratory.

We explain this clearly because we want customers to make purchasing decisions based on the work they need to perform. If your project is linked to a certification scheme, tell us which organization and test method are involved. That allows us to review the requested equipment functions with a clearer understanding of the final objective.

Keeping test results comparable

Comparability is one of the most useful outcomes of a well-planned testing process. If two door designs are tested under different pressure conditions or with different installation arrangements, the results may not provide a fair comparison. Even when the same machine is used, the operator must follow the appropriate procedure and record the conditions consistently.

For internal product development, we recommend maintaining a record of specimen construction, seal type, installation method, pressure conditions, temperature conditions, and the measured leakage values. If a manufacturer changes a seal material or modifies a door frame, these records can help the engineering team understand whether the change has affected the result.

For formal testing, the applicable standard takes priority over any general recommendation. The test report should include the information required by that procedure, and the laboratory should use suitable measuring instruments with appropriate verification or calibration records.

5. Applications Across Manufacturing, Testing, and Research

Fire door manufacturers

For fire door manufacturers, smoke leakage testing can support product development and production quality management. A manufacturer may need to compare different sealing materials, evaluate frame and leaf combinations, investigate leakage around hardware, or review the effect of changes to the assembly design.

With a properly configured smoke-control performance test apparatus, engineers can collect measurements under defined conditions rather than relying only on visual inspection. Visual checks are useful for finding obvious gaps or assembly problems, but they cannot replace a controlled leakage measurement when a formal test method requires one.

The CG2902 Smoke-Control Performance Test Apparatus for Large-Scale Fire Doors can be considered when a manufacturer's testing program involves large specimens or particular door configurations. Before selecting the system, the manufacturer should confirm the specimen size range, required test conditions, expected testing frequency, and whether the work is for development, routine inspection, or formal third-party testing.

Independent testing and inspection laboratories

Independent laboratories often handle specimens from different customers and may need to support several door designs. For these users, flexibility and clear documentation can be just as important as the basic measurement function. The laboratory needs to know what the equipment can test, which configurations require additional fixtures, and what operating conditions are supported.

We suggest preparing a list of typical and maximum specimen dimensions, together with the relevant standards and anticipated test volume. If the laboratory expects to test hinged doors, sliding doors, rolling shutters, or glazed assemblies, those requirements should be identified separately. Not every assembly type can be accommodated by the same mounting arrangement without modification.

A clear scope of supply also helps the laboratory plan installation space, supporting structures, utility connections, operator training, and maintenance. These details should be reviewed before the equipment is shipped, particularly when the system is being installed in a new laboratory or an existing room with limited access.

Construction materials and component research

Research institutions and engineering departments may use smoke leakage measurements to investigate the relationship between door construction and airflow. For example, researchers may compare sealing layouts, study leakage around the frame, or examine how a design modification affects measured airflow under a specified pressure difference.

In these applications, the test apparatus should support the required measurements while allowing researchers to document the specimen and test conditions. Where a project involves repeated experiments, a consistent mounting method and a clearly defined operating procedure can make the resulting data easier to interpret.

Research requirements may differ from routine product inspection. A research team might need additional data channels or a customized fixture, while a manufacturer may prioritize repeatability and efficient daily operation. We discuss these differences during the design stage rather than assuming that all customers need the same configuration.

Building safety and quality management

Smoke-control testing is also relevant to organizations involved in building safety, construction product evaluation, and quality management. The purpose may be to verify that a tested assembly meets a defined requirement, investigate a suspected problem, or build a documented basis for a design decision.

In every case, the equipment must be matched to the actual test method. A general smoke leakage measurement does not automatically cover fire resistance, structural strength, durability, or every other property associated with a fire door. If a project requires several types of evaluation, the test plan should identify each one separately.

Application planning table

Source note: The application categories above are practical examples based on the stated purpose of smoke-control testing. They are not market-share figures or claims that one equipment configuration automatically supports every listed application. The relevant method and final configuration must be verified for each project.

6. How We Customize, Manufacture, and Deliver the Equipment

We begin with the testing requirement, not just the product name

At Guangzhou Chuangge Automation Equipment Co., Ltd., we specialize in customized testing equipment. We know that customers may use the same general product name while expecting quite different functions. One laboratory may need a system for a defined door size and one test method. Another may require a larger opening, additional measurement functions, or a different data-recording arrangement.

For the CG2902 Smoke-Control Performance Test Apparatus, our first step is to understand the intended application. We ask about the door assembly, specimen dimensions, target standard, test conditions, measurement requirements, and installation environment. We also discuss how the customer expects to operate the system and what information needs to appear in the final test record.

Where the customer has a technical specification, test procedure, laboratory layout, or sample report, these documents help us prepare a more accurate proposal. If some requirements are not yet finalized, we can identify the open questions that need to be resolved before the design is approved.

Design review and component selection

Once the requirements are clear, the equipment design can be developed around the intended specimen and test process. Important considerations may include the supporting structure, specimen mounting, pressure-generation arrangement, measuring instruments, temperature-related functions where required, electrical controls, data recording, and operator access.

The selected components must be suitable for the intended operating conditions. For example, the measuring instruments need appropriate ranges, while the mounting structure needs to support the specimen safely. The control system should provide the functions included in the agreed scope and present relevant operating information in a usable way.

We also consider maintenance and service access. Measuring instruments may require periodic verification or calibration, and some components may need routine inspection. A practical layout makes these tasks easier to plan. The final design should document the agreed equipment functions, technical limits, customer responsibilities, and any site requirements.

Manufacturing and assembly

After the technical specification is confirmed, we arrange manufacturing and assembly according to the approved design. The work may involve structural fabrication, machining, electrical assembly, control-system integration, and installation of the selected measurement components, depending on the final configuration.

Because customized equipment is built around a particular application, changes made after design approval can affect components, assembly, software, or the production schedule. We encourage customers to review the technical proposal carefully before production begins. Confirming specimen dimensions, standards, control functions, and documentation needs at this stage helps reduce avoidable changes later.

We follow the company philosophy of ensuring survival through high technology and driving development through high quality. Our work covers a broad range of testing equipment, and we understand the importance of connecting the design with the practical needs of the laboratory. The specific inspection steps and acceptance criteria for each order are agreed according to the equipment specification.

Inspection, functional checks, and documentation

Before delivery, our standard project process includes equipment inspection, functional testing, and preparation of relevant technical documents. The purpose is to check the supplied equipment against the agreed scope and identify issues that need attention before shipment.

For a smoke-control test system, the acceptance plan should clearly identify which functions will be checked and how they will be verified. Depending on the contract, this may include checks of the assembled structure, controls, instrument connections, operating functions, and data-recording features. Any performance values or formal acceptance tests must be stated in the technical agreement rather than left open to interpretation.

Customers should also confirm which documents are required, such as an operating manual, equipment specification, electrical information, maintenance guidance, or other agreed records. If the equipment will be used in a regulated testing environment, the laboratory should separately confirm any instrument calibration, verification, or traceability requirements applicable to its work.

Production lead time and delivery planning

Our typical production period for customized testing equipment is approximately 30–60 days. The actual schedule depends on equipment specifications, the level of customization, component availability, design confirmation, and other order requirements. A straightforward configuration may follow a different schedule from a project involving a large supporting structure or special measurement functions.

We discuss the expected schedule during quotation and order confirmation. If the customer has a fixed laboratory opening date, installation deadline, or project milestone, we recommend sharing it early. This allows us to review the production plan and identify any details that could affect delivery.

Payment terms can be negotiated according to the order requirements and the agreed contract. We also confirm the delivery scope, inspection arrangements, documentation, packaging, and shipping responsibilities before the equipment is dispatched.

Packaging and transportation

Testing equipment can include structural parts, instruments, control components, and accessories that need protection during transport. We use suitable protective materials and sturdy wooden cases where appropriate to help reduce the risk of impact or movement during handling and shipping. The final packaging method depends on the equipment's size, weight, structure, and transport route.

Products can generally be shipped by sea, air, or land, depending on the destination, urgency, and logistics arrangements. Sea freight may be appropriate for larger equipment and planned international shipments, while air transport may be considered when delivery speed is a priority and the shipment is suitable. Land transport can be used where the route and delivery arrangements allow.

Before dispatch, customers should confirm the delivery address, unloading arrangements, access dimensions, and any lifting equipment required at the destination. Large test systems may need adequate door clearance and floor space for installation. Reviewing these points in advance can make receiving and commissioning much smoother.

7. Why Work With Guangzhou Chuangge Automation Equipment Co., Ltd.?

Experience with customized testing equipment

We focus on designing and supplying testing equipment for practical industrial and laboratory applications. Our product fields include construction materials and components, wires and cables, plastics and textiles, electrical plugs, sockets and switches, electronic products, and home appliances. This range of work means that we regularly deal with projects where the test objective, relevant standard, specimen design, and measurement method must be considered together.

For customers seeking a CG2902 Smoke-Control Performance Test Apparatus for Large-Scale Fire Doors, this customization approach is important. We do not believe that a product name alone provides enough information to define a complete testing system. We prefer to review the customer's actual needs and prepare a configuration that can be evaluated against those requirements.

Quality and management systems

Our company has obtained ISO 9001 quality management system, ISO 14001 environmental management system, and ISO 45001 occupational health and safety management system certifications. These management-system certifications relate to how an organization manages quality, environmental responsibilities, and occupational health and safety. They should not be confused with product-specific approval or certification of a particular testing machine.

We also have a portfolio of more than 20 patents, including invention patents, utility model patents, and software patents. This intellectual property portfolio reflects our work in equipment development and related technical areas. The relevance of any particular patent depends on the design and application involved, so we do not treat the total number of patents as proof of a specific performance result.

Communication before and after the order

Customized equipment projects involve decisions that are easier to resolve before production than after delivery. We encourage customers to share their test standard, specimen drawings, target dimensions, required operating conditions, and reporting expectations early. If a requirement is unclear, it is better to identify it during the technical discussion than to discover the issue during installation.

We also encourage buyers to ask for a clear scope of supply. The quotation and technical agreement should identify the main equipment, included instruments, control functions, documentation, inspection arrangements, packaging, delivery terms, and any items supplied by the customer. If installation, training, or commissioning is needed, these services should be discussed and confirmed separately.

For international customers, we understand that shipping and site preparation are part of the purchasing decision. We can discuss the available transportation methods and packaging requirements according to the equipment and destination. The customer should provide the delivery location and relevant site information so that both sides can plan the shipment and receiving process properly.

What we need to prepare a useful quotation

To help us assess a CG2902 project efficiently, please provide as much of the following information as possible:

• The required test standard and edition, including any local adoption or certification requirement.

• The type of door assembly to be tested, such as a hinged door, sliding door, rolling shutter, or glazed assembly.

• The expected specimen dimensions, frame details, and installation arrangement.

• The required test conditions, including pressure and temperature requirements where applicable.

• The required airflow measurement range, recording method, calculations, and test-report format.

• The intended use, such as research, product development, routine quality checks, or formal laboratory testing.

• The installation location, available space, delivery destination, and expected project schedule.

These details help us distinguish essential functions from optional features. They also make it easier to prepare a technical proposal that both parties can review before production. If you are still developing your test plan, we can begin by reviewing the information already available and identifying which requirements need further confirmation.

8. Frequently Asked Questions About the CG2902 Smoke-Control Performance Test Apparatus

Q1. What is the main purpose of the CG2902 Smoke-Control Performance Test Apparatus?

The equipment is intended for smoke-control performance testing of large-scale fire door assemblies. A typical test evaluates airflow leakage through a closed assembly under defined conditions. The exact functions, supported specimen dimensions, operating conditions, and measurement capabilities depend on the confirmed equipment configuration.

Q2. Can the equipment test different sizes of fire doors?

That depends on the final mounting structure and the dimensions specified for the project. Before ordering, please provide the minimum and maximum specimen dimensions, together with the door frame and opening details. We can then review the required test opening and determine the appropriate configuration. Compatibility with multiple sizes should be confirmed in the technical agreement.

Q3. Does the apparatus support both ambient-temperature and medium-temperature testing?

These are different test conditions and may require different equipment functions. ISO 5925:2025 covers both ambient-temperature and medium-temperature leakage tests, but that does not mean every smoke-control test apparatus automatically supports both. Please identify the required method and temperature conditions so that the necessary functions can be included in the final specification.

Q4. Which standards should we consider when purchasing this equipment?

ISO 5925:2025 is a key reference for ambient-temperature and medium-temperature leakage tests of smoke-control door and shutter assemblies and specified self-closing glazed elements. Depending on the target market, EN 1634-3 or a relevant national adoption may also need to be reviewed. The correct standard and edition should be confirmed with the responsible laboratory, certification body, or authority.

Q5. Does a low leakage result automatically mean that a fire door is certified?

No. A leakage measurement is a test result obtained under specified conditions. Whether the door meets the required acceptance limit depends on the applicable criteria, and certification may involve additional procedures and documentation. The testing equipment itself does not automatically certify the door or the laboratory.

Q6. Can you customize the measurement and data-recording functions?

Customization can be discussed according to the test method and the customer's needs. Relevant topics may include pressure monitoring, airflow measurement, temperature measurement where required, digital recording, calculations, and report formats. The available functions and technical limits must be reviewed and confirmed before production.

Q7. How long does production usually take?

Our typical production period for customized testing equipment is around 30–60 days. The actual lead time depends on the approved specification, customization requirements, component availability, and production arrangements. We confirm the expected schedule during the quotation and order process.

Q8. What is included before delivery?

Our delivery process includes equipment inspection, functional testing, and relevant technical documentation according to the agreed scope. The contract should identify the specific inspection items, acceptance criteria, documents, and any additional verification or calibration requirements that apply to the project.

Q9. How is the equipment packaged and shipped?

We select protective packaging according to the equipment structure, size, and shipping conditions. Protective materials and sturdy wooden cases may be used to help reduce transport damage. Shipping options generally include sea, air, and land transport, subject to destination, urgency, and logistics arrangements.

Q10. What information should we send to request a quotation?

Please send the applicable test standard, door dimensions, assembly type, required pressure and temperature conditions, measurement requirements, data-reporting needs, delivery location, and target schedule. Drawings, a sample test report, or a laboratory specification are also helpful. The more clearly the test objective is defined, the easier it is for us to propose a suitable configuration.

Q11. Can this equipment replace a fire resistance Test Furnace?

Not automatically. Smoke leakage testing and Fire Resistance Testing evaluate different performance characteristics. A smoke-control test focuses on leakage under defined conditions, while a fire resistance test evaluates specified criteria during fire exposure. If a project requires both, the testing plan should identify the separate equipment and procedures needed for each test.

Q12. How can we confirm that the final configuration meets our laboratory needs?

Start by comparing the proposed equipment specification with the full applicable standard and the laboratory's testing procedure. Confirm the specimen range, mounting method, pressure and temperature conditions, measurement functions, reporting requirements, and acceptance criteria. Where formal accreditation or certification is involved, consult the relevant body about any additional requirements before placing the order.
