电线电缆耐火性能检测标准使用梳理与讨论

Combing and Discussion on the Use of Detection Standards of Fire Resisting Performance for Wires and Cables

耐火性能的好坏关系到电缆产品在火灾条件下的安全稳定运行,直接影响人员的逃生疏散及灾后救治工作的开展。梳理了耐火试验相关标准和使用方法,根据工作实践总结了耐火试验中易被忽视的问题,并给出了试验步骤与注意事项,为行业人员提供了参考和借鉴。

The fire resisting performance is related to the safe and stable operation of cable products in fire,which directly affects the per-sonnel evacuation and the post-disaster treatment.This paper combs the standards and methods of fire resistance tests,summarizes the prob-lems that are easy to be ignored in relevant tests according to work practices,and gives out the test procedures and matters needing attention,which provides reference for people in the industry.
