GB 17428-1998 stipulates the fire resistance test method of ventilated pipelines. The ventilated pipeline specimens are placed in a simulated fire environment and heated by Linear dispersion according to a specific temperature rise to monitor the integrity, thermal insulation and anti-deformation ability of the pipeline. Clarify the requirements for the construction of test equipment, temperature rise system, Measuring location and accuracy, covering the details of specimen preparation and installation. Through this standard, the performance of ventilated pipelines in fires can be evaluated uniformly, providing a basis for production, testing and building fire protection design, ensuring the safety of the ventilated system in the event of a fire, avoiding the spread of fire, and ensuring the safety of personnel and property.
