国标、IEC标准与英标电线电缆耐火特性试验差异

Difference in Fire Resistance Property Test of Cables and Wires under Chinese Standard,IEC Standard and British Standard

为了评定电线电缆耐火特性的优劣,我国、IEC和英国都制定了电线电缆耐火特性试验标准。文章概述耐火特性试验标准的发展过程,从标准制定的出发点、标准的适用范围、耐火试验项目和要求等方面简要分析这些标准的差异性;并分析我国电线电缆耐火特性标准存在的不足,为以后标准修订提供参考。

China, IEC and Britain all tormulated fire resistance test standard for cables and wires to evaluate the quality of cable and wire＇s fire resistance property. This article summarizes the development of fire resistance property test Standards, analyzes the differences in their purposes, scope of application, test items and requirements, and explores the deficiency of existing China standards for cables and wires fire resistance property to provide reference for its further revision.
