IEC 60331-23：Tests for Electric Cables under Fire Conditions - Circuit Integrity - Part 23: Procedures and Requirements - Electric Data Cables
Abstract摘要
This part of IEC 60331 specifies the test procedure and gives the performance requirement, including a recommended flame application time, for electric data cables required to maintain circuit integrity when subjected to fire under specified conditions.
It describes the means of sample preparation, continuity checking arrangements, electrical testing procedure, method of burning the cables and gives requirements for evaluating test results.
It covers electric data cables which have no rated voltage and are used for extra low voltage circuits.
