Abstract 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.
