Customized 5 × 5 m Smoke Leakage Testing System for Fire Doors

Project Background

Fire doors play an important role in limiting the spread of smoke and fire within buildings. In the event of a fire, smoke leakage through gaps around a closed fire door can affect evacuation routes, reduce visibility, and compromise the effectiveness of smoke control measures. Testing the smoke leakage performance of fire doors is therefore an important part of evaluating their suitability for fire safety applications.

Guangzhou Chuangge Automation Equipment Co., Ltd. provided a customized smoke leakage testing system for the Sichuan Fire Research Institute of the Ministry of Emergency Management and the National Quality Inspection and Testing Center for Fireproof Building Materials. The project included one large-scale testing unit with dimensions of 5 × 5 m, designed around the customer's specific testing requirements.

Customized Equipment Design

The 5 × 5 m configuration provides a large testing space for accommodating the specified test assembly and associated equipment. For specialized fire door testing, the overall chamber dimensions and installation arrangement must be considered alongside the size of the test specimen, sealing structure, airflow conditions, pressure measurement requirements, and testing procedures.

A customized design allows these factors to be considered during project planning. The equipment configuration can be coordinated with the customer's laboratory layout and intended test applications, helping establish a suitable arrangement for testing smoke leakage performance.

Smoke Leakage Testing Considerations

Smoke leakage testing generally evaluates the amount of air or smoke passing through gaps around a closed door assembly under defined pressure conditions. The measured leakage performance can be affected by door dimensions, frame installation, seals, hardware, pressure differences, and the condition of the test specimen.

For reliable testing, the equipment must be configured to support the required pressure conditions and measurement method. The applicable testing standard determines the test procedure, measurement points, acceptance criteria, and reporting requirements. Specific operating ranges and measurement accuracy should be confirmed against the project's agreed technical specifications.

Value of the Customized Solution

The 5 × 5 m smoke leakage testing system demonstrates Chuangge's ability to develop specialized testing equipment for professional inspection and research organizations. Rather than relying solely on standard equipment dimensions, the project configuration can be planned around the customer's intended test assemblies and laboratory requirements.

For inspection institutions, a clearly defined equipment configuration helps coordinate specimen installation, testing procedures, equipment operation, and laboratory space planning. The final equipment acceptance process should follow the agreed technical specifications and relevant testing requirements.
