低压电缆耐火试验国标和英标的差异分析

摘要

On the basis of the comparison of difference between the national standards for fire-resistant test of low -voltage cable, GB 19216. 21-2003 / IEC 60331-21： 1999 Tests for Electric Cables under Fire Conditions — Circuit integrity — Part 21： Procedures and Requirements—Cables of Rated Voltage up to and Including 0. 6 / 1. 0 kV, and British standard BS 6387： 1994 Specification for Performance requirements for cables required to maintain circuit integrity under fire conditions, the standpoints, test content and methods are analyzed; after the comparison and analysis of the difference, the test content of BS 6387 ： 1994 is introduced in detail, so as to provide reference for designers to understand the difference between the two standards.%通过对比低压电缆耐火试验国家标准GB 19216.21-2003/IEC60331-21：1999《在火焰条件下电缆或光缆的线路完整性试验第21部分：试验步骤和要求额定电压0.6/1.0kV及以下电缆》和英国标准BS 6387：1994《Specification for Performance requirements for cables required to maintain circuit integrity under fire conditions》的差异,分析两个标准制订的出发点、试验内容和试验方法。对比分析存在的差异性,并详细介绍BS 6387：1994的试验内容,为设计人员了解两个标准的差别提供参考。
