    Abstract - (Show below) - (Hide below)

    IEC 60331-21:1999 Specifies the test procedure and gives the performance requirement, including a recommended flame application time, for cables of rated voltages up to and including 0,6/1,0 kV required to maintain circuit integrity when subjected to fire under specified conditions. Describes the means of sample preparation, continuity checking arrangements, electrical testing procedure, method of burning cables and gives requirements for evaluating test results. It is intended to cover low voltage power cables and gives requirements for evaluating test results.
