Oil and grease in water are not always easy to deal with. A sample may look clean at first glance, yet still contain oil residues from industrial production, equipment maintenance, food processing, or wastewater discharge. If these substances are not measured properly, a laboratory may miss useful information about water quality, process conditions, or the performance of a treatment system.

At Guangzhou Chuangge Automation Equipment Co., Ltd., we understand that reliable testing starts with the right equipment and a clearly defined test method. Our work focuses on customized testing equipment for industrial and laboratory applications. For customers looking for an Oil-Grease Separation Test Apparatus, we discuss the sample type, required analytical method, laboratory workflow, and relevant standards before confirming the equipment configuration.

Oil-grease separation is an important step in many analytical procedures. Depending on the method, oil and grease may need to be separated from a water sample using a suitable extraction process before the extract is measured by weighing or another analytical technique. The separation process must be appropriate for the substances being measured, because different methods do not necessarily measure exactly the same group of compounds.

We do not treat every oil and grease testing project as identical. A laboratory testing industrial wastewater may have different needs from a research institution studying water quality or a manufacturer checking process samples. Our goal is to understand those differences and discuss a practical testing solution that fits the intended procedure.

With our experience in customized testing equipment, knowledge of relevant standards, and manufacturing capabilities, we support customers who need equipment planned around real testing requirements. Our company holds ISO 9001, ISO 14001, and ISO 45001 management system certifications, and our intellectual property portfolio includes more than 20 patents across invention patents, utility model patents, and software patents.

1. What Is an Oil-Grease Separation Test Apparatus?

Understanding the role of oil and grease separation

An Oil-Grease Separation Test Apparatus is equipment intended to support the separation or preparation stage of oil and grease analysis. The exact structure and functions depend on the analytical method selected for the project. In some procedures, the sample is mixed with a suitable extraction solvent so that certain oil-related substances move from the water into the solvent. The two liquid layers can then be separated for further analysis.

In other analytical workflows, separation may involve different laboratory components or sample preparation steps. For this reason, the product name alone does not tell a buyer whether the equipment is intended for solvent extraction, liquid-liquid separation, heating, filtration, concentration, or another process. We recommend confirming the required method before deciding on the final equipment configuration.

The term “oil and grease” is also method-dependent. It can refer to a group of extractable substances measured under a defined procedure rather than one single chemical compound. Depending on the method, the measured material may include certain hydrocarbons, animal fats, vegetable oils, waxes, greases, soaps, and related substances. The result therefore needs to be interpreted according to the method used.

For laboratories working with wastewater, industrial discharge, or environmental samples, this distinction is important. A result obtained through one analytical method may not be directly comparable with a result from another method if the two procedures measure different substances or use different sample preparation steps.

Why separation matters before analysis

Water samples can contain suspended particles, dissolved substances, emulsified oils, and other materials that complicate analysis. If sample preparation is not handled correctly, some of the target material may be lost, while other substances may be carried into the final extract and affect the result.

A suitable separation process helps the operator prepare the sample according to the analytical method. Depending on the procedure, this may involve mixing the sample with a solvent, allowing the phases to separate, collecting the required layer, and preparing it for measurement. Each step needs to follow the method because the choice of solvent, mixing conditions, separation time, and handling procedure can influence the result.

For example, a sample containing a stable emulsion may not separate in the same way as a sample containing a visible layer of free oil. An operator cannot simply assume that every sample will form two clear layers immediately. The method may specify particular handling steps for difficult samples, and those instructions should be followed rather than replaced with an improvised procedure.

We encourage customers to explain their sample characteristics before selecting an Oil-Grease Separation Test Apparatus. Information about sample source, expected oil content, suspended solids, analytical method, and sample throughput can help us understand what the equipment needs to support.

Typical applications of oil and grease analysis

Oil and grease analysis is used in environmental laboratories, wastewater treatment facilities, industrial plants, research institutions, and quality inspection organizations. It can help laboratories investigate the composition of water samples, monitor changes in process water, and evaluate samples collected as part of an environmental monitoring program.

In industrial settings, oil residues may come from lubricants, hydraulic systems, machinery cleaning, metalworking processes, or other production activities. In food-related operations, oils and fats may enter wastewater through processing and cleaning. The substances present in each sample can differ, so the selected analytical method should match the intended measurement.

For environmental applications, oil and grease results can support broader assessments of wastewater quality and treatment performance. However, one measurement cannot explain every aspect of water quality. Depending on the project, laboratories may also need to measure suspended solids, chemical oxygen demand, specific hydrocarbons, or other parameters.

Our role is to discuss the equipment needed for the intended test procedure and help customers define the requirements before production. We do not assume that a single apparatus can replace every analytical instrument or perform every stage of a complete laboratory method.

2. Working Principle and Typical Testing Workflow

How an oil and grease separation process works

The working principle depends on the analytical method used. In a common solvent-extraction workflow, the operator prepares a water sample and adds a suitable solvent according to the method. After mixing, the sample is allowed to separate into phases. The solvent phase containing the target extractable material is collected and processed for the next analytical step.

For a gravimetric method, the collected extract may be processed so that the solvent is removed under specified conditions. The remaining extractable material is then weighed, and the result is calculated according to the method. In a chromatographic method, the extract is prepared for analysis using the specified instrument and procedure. Other methods may use a different measurement principle.

The apparatus supports the relevant preparation or separation operations, but the equipment alone does not determine the final analytical result. Sample collection, preservation, reagent quality, solvent selection, extraction efficiency, handling losses, measurement technique, and quality control all matter.

For this reason, we recommend that buyers identify the standard or laboratory method they intend to follow before requesting a quotation. If the method requires specific separation vessels, heating arrangements, extraction accessories, or other components, these requirements should be included in the technical discussion.

A typical workflow for solvent-extraction analysis

1. Confirm the analytical method. Identify the required standard, the type of sample, the substances being measured, and the reporting units.

2. Collect and preserve the sample. Follow the method's instructions for sample containers, preservation, storage, and holding time. Improper sampling can lead to the loss of oil or grease before analysis begins.

3. Prepare the sample. Measure the required sample quantity and complete any specified preparation steps before extraction.

4. Carry out extraction or separation. Use the solvent, apparatus, mixing procedure, and separation conditions specified by the method.

5. Collect the required phase. Separate and transfer the relevant extract carefully. Avoid losing material that should be included in the analysis.

6. Complete the measurement step. Depending on the selected method, this may involve gravimetric measurement, chromatography, or another approved analytical technique.

7. Review quality control and calculate the result. Apply the required blanks, calibration or verification steps, calculations, and reporting rules.

This is a general overview of a common analytical workflow, not a complete operating procedure for a particular instrument or standard. Exact sample quantities, solvents, preservation conditions, extraction steps, and calculations must come from the applicable method. Operators should consult the complete procedure before carrying out testing.

What can affect the final result?

Several factors can influence oil and grease analysis. One is sample collection. Oil and grease may adhere to sampling equipment or container surfaces, so the method's requirements for containers and transfer procedures are important. If the sample is not representative, even a well-controlled laboratory procedure cannot fully correct the problem.

Another factor is the extraction process. The selected solvent must be suitable for the method, and the operator must follow the specified mixing and separation procedure. Incomplete extraction can cause some target material to remain in the original sample, while poor phase separation can make it difficult to collect the required extract cleanly.

Sample composition also matters. Suspended solids, emulsions, and substances that are extractable but not part of the intended target group can affect the measured value. Some methods include additional steps to distinguish non-polar petroleum-related material from a broader group of extractable substances.

Finally, the measurement stage must be handled correctly. In a gravimetric procedure, for example, the condition of the collection vessel, solvent removal, weighing practice, and blank correction can all affect the calculated result. In an instrumental method, calibration, instrument condition, and data interpretation introduce their own requirements.

For these reasons, accurate oil and grease content analysis depends on the complete procedure, not only on the separation apparatus. Equipment should support the method, while operators need appropriate training, quality control, and clear records.

3. Key Equipment Considerations and Customization Options

Start with the intended method, not just the product name

When customers contact us about an Oil-Grease Separation Test Apparatus, we first ask how the equipment will be used. The answer affects the required components, operating arrangement, sample handling process, and any supporting equipment needed to complete the analysis.

For example, a laboratory following a solvent-extraction and gravimetric method may need a setup that supports sample extraction and phase separation, together with separate equipment for solvent removal and weighing. A laboratory using a chromatographic method will have different downstream analytical needs. The separation apparatus should be planned as part of the complete workflow rather than treated as a replacement for every instrument involved.

We discuss these requirements with customers before confirming a configuration. Where the application calls for customization, the proposal can be developed around the agreed test procedure and practical laboratory needs. Any functions, accessories, and performance requirements should be listed in the technical specification so that both sides have a clear reference.

Important points to review before purchasing

Sample type and volume: The nature and quantity of the sample affect the choice of vessels, handling arrangements, and workflow. Buyers should provide the expected sample volume and describe whether samples are typically clean water, industrial wastewater, or another matrix.

Analytical method: Different methods can measure different groups of substances. The equipment configuration must be compatible with the method the laboratory intends to use. If a customer has a required standard or internal procedure, it should be provided during the inquiry stage.

Number of samples: A laboratory processing a few samples per day may have different workflow priorities from a laboratory handling a large routine testing workload. Expected throughput can influence the number of processing positions, arrangement of work areas, and the need for accessories.

Material compatibility: Equipment components that contact samples or solvents must be suitable for the intended chemicals and operating conditions. The required materials should be reviewed during technical confirmation rather than assumed from general product descriptions.

Operator safety: Solvents may be flammable, harmful, or require specific handling controls. The laboratory must use appropriate ventilation, personal protective equipment, storage arrangements, and waste-handling procedures. Equipment selection should be considered together with the laboratory's chemical safety requirements.

Cleaning and maintenance: Residue carried over from one sample to another can affect subsequent measurements. Buyers should consider how vessels and relevant components will be cleaned, inspected, and maintained under the selected procedure.

Documentation and inspection: Confirm which operating instructions, technical documents, functional checks, and acceptance records are required. Defining these details before manufacturing helps avoid misunderstandings at delivery.

Reference comparison: common analytical approaches

The following table compares several established approaches used in oil-related water analysis. It is a general method-selection guide rather than a claim that every Oil-Grease Separation Test Apparatus can perform all the listed methods.

See the references below for method scope and status.

• U.S. EPA Method 1664 Revision B

Why a customized configuration can help

Laboratories rarely work under exactly the same conditions. They may use different sample containers, process different sample quantities, follow different standards, or have different requirements for bench space and operator access. A customized arrangement can help the equipment fit the laboratory's established procedure.

However, customization should not mean making uncontrolled changes to the analytical method. If the method specifies particular vessels, solvents, mixing conditions, separation steps, or sample volumes, those requirements need to be preserved. Any proposed change should be reviewed to determine whether it remains suitable for the intended method.

We encourage customers to share their test procedure, sample information, equipment requirements, and available laboratory space. Drawings, photographs, or a list of current equipment can also help us understand the intended workflow. With this information, we can discuss which functions should be included and which items may need to be supplied separately.

4. Technical Advantages and Factors Behind Reliable Analysis

Support a controlled sample preparation process

A useful oil-grease separation setup should support the required sample preparation steps in a clear and repeatable way. Operators need to understand where the sample is placed, how the relevant separation operation is performed, how the extract is collected, and how the prepared sample moves to the next analytical stage.

We approach customized equipment projects by reviewing the intended operation and clarifying the required functions. Rather than relying on vague claims such as “high precision” without a defined test basis, we prefer to discuss the actual requirements: the method to be followed, the expected sample range, the relevant accessories, and the checks needed before delivery.

This approach is especially useful for laboratories that need to integrate new equipment into an existing testing process. By confirming the workflow and the equipment's role early, the customer can better understand what the apparatus will do and which additional instruments or laboratory facilities remain necessary.

Improve consistency through defined operating procedures

Repeatability does not come from equipment alone. Operators need a written procedure that defines sample preparation, solvent use, extraction conditions, separation, transfer, measurement, and reporting. The same procedure should be followed consistently so that changes in results are more likely to reflect differences in samples rather than differences in handling.

Routine checks can also help identify problems. Depending on the method, laboratories may use reagent blanks, method blanks, recovery checks, duplicate samples, reference materials, or other quality-control measures. The exact requirements should come from the analytical method and the laboratory's quality system.

Cleaning is another practical consideration. Oil and grease residues can remain on glassware, fittings, or sample-contact surfaces. If these residues enter a later sample, the measured result may be higher than expected. The cleaning procedure should therefore be suitable for the materials being measured and should follow the laboratory's approved method.

Reference comparison: factors that influence test quality

The table below summarizes common sources of variation in oil and grease analysis and the practical checks laboratories can consider. These are general quality considerations, not performance specifications for a particular apparatus.

Source: The U.S. EPA's Method 1664 Revision B provides procedural requirements for extraction and gravimetric determination of n-hexane extractable material. ISO 9377-2:2000 specifies a method for determining hydrocarbon oil index in water by solvent extraction and gas chromatography. These references demonstrate why sample preparation and method-specific controls matter; the exact quality-control requirements must be taken from the method used by the laboratory.

Reference links: EPA Method 1664 Revision B and ISO 9377-2:2000.

Plan the equipment around laboratory safety

Some oil and grease methods use organic solvents. Depending on the selected solvent, the work may involve flammable vapors, harmful exposure, or special waste-handling requirements. Laboratory personnel should review the solvent safety data sheet and follow the applicable rules for ventilation, personal protective equipment, storage, spill response, and disposal.

Equipment selection should take these conditions into account. Buyers should explain the chemicals used, the expected working environment, and any relevant laboratory safety requirements before the configuration is finalized. A separation apparatus does not replace a suitable fume hood or other required engineering controls unless the supplied design and its documented use specifically provide for those functions.

We recommend confirming the intended solvents and workflow early in the project. This allows the technical proposal to be reviewed against the actual application and helps avoid assumptions about chemical compatibility or safety features that have not been specified.

5. Applications in Environmental Monitoring and Industrial Quality Control

Wastewater treatment and environmental laboratories

Wastewater can contain oil and grease from industrial processes, vehicle maintenance, food production, equipment cleaning, and other activities. Environmental laboratories may analyze samples to investigate discharge quality, monitor treatment processes, or support compliance assessments where the relevant rules require this parameter.

An Oil-Grease Separation Test Apparatus may support the sample preparation stage of these analyses, depending on the chosen method. The laboratory must first determine which parameter is required, because a broad oil-and-grease measurement is not necessarily the same as a measurement of a specific petroleum hydrocarbon group.

For treatment facilities, results may be compared over time to identify changes in the incoming wastewater or the performance of a process. Reliable comparison requires consistent sampling, the same applicable method, and appropriate quality-control procedures. A single result should be interpreted in context rather than used as the only basis for judging an entire treatment system.

Petrochemical and machinery-related industries

Industrial facilities may generate wastewater containing lubricating oils, hydraulic fluids, fuels, or other oil-related substances. These samples can differ significantly in composition. Some may contain free oil, while others may contain dispersed droplets, emulsions, or a mixture of substances that require careful sample preparation.

Laboratories supporting these industries should select a method suited to the intended measurement. If the goal is to determine a defined hydrocarbon oil index, a method based on solvent extraction and gas chromatography may be appropriate where specified. If the requirement concerns method-defined extractable material measured gravimetrically, a different procedure may apply.

We discuss the intended measurement with customers before proposing an equipment configuration. Understanding the source of the sample, the expected substances, and the reporting requirement helps determine whether the requested apparatus is suitable for the planned workflow.

Food processing and commercial operations

Food processing and commercial cleaning operations may generate wastewater containing animal fats, vegetable oils, and other organic residues. The composition can change according to the product being processed, the cleaning method, and the stage of production.

For these samples, it is important to confirm that the selected analytical method covers the substances of interest. A method designed for a particular group of hydrocarbons may not provide the same information as a broader oil-and-grease method. The laboratory should choose the procedure according to its monitoring objective and applicable requirements.

Where samples are emulsified or contain significant suspended matter, operators should follow the method's instructions for handling those conditions. Improvised changes may affect recovery or make the results difficult to compare with the required limits.

Research institutions and third-party inspection laboratories

Research institutions and independent laboratories may handle samples from different industries, environmental studies, or customer investigations. Their equipment needs often depend on the range of analytical methods, sample volume, and number of tests performed each day.

For these organizations, clear documentation and a defined operating workflow are particularly useful. A well-planned setup should allow operators to understand the sample preparation steps, maintain traceable records, and clean the equipment appropriately between samples. Where multiple analytical methods are used, the laboratory should clearly identify which configuration and procedure apply to each test.

We work with customers to review their laboratory requirements and discuss a suitable customized solution. If the project includes particular sample holders, separation vessels, accessories, or documentation needs, these should be included in the technical inquiry so that the proposed scope can be evaluated properly.

Manufacturing quality control

Manufacturing facilities may use oil and grease analysis to investigate process water, cleaning systems, or wastewater streams. The results can help teams identify changes in operating conditions and decide whether further investigation is needed.

For routine quality control, the testing workflow should be practical and consistent. Operators need a clear procedure for sample identification, preparation, separation, measurement, and recordkeeping. Equipment should be selected to support that process without adding unnecessary steps or features that the method does not require.

Before purchasing, manufacturers should consider the number of samples, the expected sample composition, the analytical method, and the available laboratory space. These details are often more useful for equipment selection than a generic request for an apparatus described as accurate or efficient.

6. Manufacturing, Quality Inspection, and Delivery at Guangzhou Chuangge

Understanding the project before manufacturing

At Guangzhou Chuangge Automation Equipment Co., Ltd., we treat customized testing equipment as a project that begins with technical clarification. We first review what the customer needs to test, which procedure will be followed, and what functions the equipment must provide. This helps establish a clear basis for the configuration and reduces the risk of misunderstanding the requested scope.

For an Oil-Grease Separation Test Apparatus, the discussion may cover sample types, the intended analytical method, required vessels or accessories, expected workflow, and any special requirements for laboratory integration. We also clarify whether the requested equipment is intended only for separation or whether the project requires additional sample preparation functions.

After the main requirements are understood, we can discuss the technical configuration, production schedule, inspection arrangements, documentation, and shipping plan. If a customer has an established laboratory procedure, providing it early is especially helpful because it allows the proposed equipment to be evaluated against the actual work to be performed.

Production cycle and project planning

Our typical production cycle for testing equipment is approximately 30 to 60 days, depending on the equipment specification and customization requirements. The actual lead time should be confirmed for each order after reviewing the configuration, manufacturing requirements, and agreed commercial terms.

Customized projects can differ in their component requirements, mechanical arrangement, controls, accessories, and documentation. For this reason, we do not assume that every equipment order can be completed on the same schedule. The confirmed production plan should reflect the final technical agreement and the scope of supply.

We encourage customers to raise any special delivery or acceptance requirements before production begins. If the equipment needs to fit a particular laboratory bench, connect with an existing process, or be supplied with specified accessories, these points should be documented and reviewed in advance.

Functional inspection and performance verification

Before delivery, each unit undergoes functional inspection and performance verification. These checks are intended to confirm the operation of the supplied equipment against the agreed configuration. The inspection items depend on the equipment design, functions included in the order, and technical requirements established for the project.

For an oil-grease separation system, buyers should identify any special acceptance checks that are important to their intended application. The exact items need to be agreed before manufacturing so that the inspection process has a clear reference. If the customer requires specific records or additional technical documentation, these requirements should also be discussed during the quotation stage.

Equipment inspection and analytical-method validation are not the same thing. A functional inspection checks the equipment against its agreed scope, while a laboratory's analytical method may require separate validation, verification, calibration, quality-control samples, or other procedures. The laboratory remains responsible for confirming that its overall testing method is appropriate for the intended measurement.

Operating instructions and technical documents

We provide operating instructions and technical documentation as agreed for the project. These documents help customers understand the supplied configuration and establish a reference for setup, routine operation, and maintenance.

If the customer needs a particular document format, additional technical details, or supporting information for internal records, we recommend specifying those requirements before the order is finalized. Clear documentation requirements help both sides understand what will be supplied with the equipment.

Packaging and transportation

Testing equipment may include components that need protection against impact, vibration, moisture, or movement during transport. We use protective materials and sturdy wooden cases as appropriate to the equipment and shipping arrangement. The packaging plan depends on the size, structure, and handling requirements of the shipment.

We can discuss sea, air, or land transportation according to the destination, schedule, and delivery requirements. The best option depends on factors such as shipment dimensions, cost, urgency, and local import arrangements. International buyers should confirm the delivery address, consignee information, customs documentation, and any special handling instructions before dispatch.

Payment and commercial coordination

Payment terms are negotiable and should be confirmed in the quotation or sales agreement. For customized equipment, we encourage customers to review the technical scope, lead time, payment arrangement, inspection requirements, packaging, and shipping responsibilities together before confirming the order.

This helps ensure that both parties understand the equipment being supplied and the conditions under which it will be delivered. A clear agreement is especially important when the project includes customization, optional accessories, special documentation, or specific acceptance requirements.

7. Why Choose Guangzhou Chuangge Automation Equipment Co., Ltd.?

Customization based on real testing requirements

We specialize in customized testing equipment for industrial and laboratory applications. We understand that customers need more than a general product description: they need to know whether the equipment is suitable for their test method, sample type, and working environment.

Our approach begins with the application. We review the intended procedure, clarify the required functions, and discuss the configuration before manufacturing. This is particularly useful for laboratories with specific sample-handling requirements or existing workflows that the new equipment must support.

For oil and grease analysis, we pay attention to the distinction between sample separation and the complete analytical process. If the laboratory also needs a measurement instrument, solvent-removal equipment, or other accessories, those requirements should be identified so that the project scope can be discussed clearly.

Knowledge of relevant standards

Testing equipment should be selected in relation to the method it is intended to support. Standards and analytical procedures define important details such as sample preparation, reagents, extraction conditions, measurement, quality control, and reporting. We encourage customers to provide the exact standard or method reference so that the proposed configuration can be reviewed against their needs.

For example, U.S. EPA Method 1664 Revision B uses extraction and gravimetry to determine n-hexane extractable material and silica-gel-treated n-hexane extractable material in specified water and wastewater matrices. ISO 9377-2:2000 describes a solvent-extraction and gas-chromatography method for determining hydrocarbon oil index in water. These methods have different scopes and measurement principles, so they should not be treated as interchangeable.

We do not assume that every oil and grease testing project follows the same standard. The appropriate method depends on the customer's sample, measurement objective, regulatory requirements, and intended reporting use. Confirming these details early helps avoid choosing equipment based only on a broad product name.

Management systems and intellectual property

Our company holds ISO 9001 quality management system certification, ISO 14001 environmental management system certification, and ISO 45001 occupational health and safety management system certification. These certifications relate to our management systems in their respective areas. They should not be interpreted as automatic certification of every individual testing apparatus or as a replacement for equipment-specific verification.

Our intellectual property portfolio contains more than 20 patents, including invention patents, utility model patents, and software patents. This portfolio supports our ongoing work in testing equipment development and customization. For each project, we focus on understanding the technical need and agreeing on a practical configuration that can be manufactured and inspected against defined requirements.

Clear communication from inquiry to delivery

We believe that a successful equipment project depends on clear communication. Buyers should understand which functions are included, what information is needed before production, how the equipment will be inspected, and which documents will be provided. We aim to clarify these points before manufacturing begins.

For international customers, project planning also includes production timing, packaging, transportation, and commercial terms. We discuss sea, air, or land shipping according to the order and destination, and we use protective materials and sturdy wooden cases as appropriate to help protect the equipment in transit.

8. Frequently Asked Questions About Oil-Grease Separation Test Apparatus

Q1. What is an Oil-Grease Separation Test Apparatus used for?

It is used to support the separation or sample preparation steps involved in oil and grease analysis. Depending on the selected method and equipment configuration, it may support solvent extraction, liquid-phase separation, or related preparation operations. The final measurement may require separate equipment, such as a balance or chromatographic instrument.

Q2. Can this apparatus measure oil and grease content directly?

That depends on the equipment configuration. A separation apparatus may prepare an extract for later measurement rather than directly determine the final concentration. The measurement step may involve gravimetry, chromatography, or another method-specific technique. Buyers should confirm whether they need separation equipment only or a more complete analytical setup.

Q3. Which standards are relevant to oil and grease analysis?

The relevant method depends on the sample and the parameter being measured. Examples include U.S. EPA Method 1664 Revision B for n-hexane extractable material using extraction and gravimetry, and ISO 9377-2:2000 for hydrocarbon oil index using solvent extraction and gas chromatography. The laboratory should confirm the applicable edition, regulatory acceptance, and product-specific requirements before selecting equipment.

Q4. Are oil and grease content and hydrocarbon oil index the same measurement?

Not necessarily. These terms can refer to different method-defined parameters. A broad oil-and-grease method may include several types of extractable substances, while a hydrocarbon oil index method has its own defined scope and measurement procedure. Results from different methods should not be assumed to be directly comparable without checking their scope and definitions.
