IEC 60331-31 Ed. 1.0 b:2002

Tests for electric cables under fire conditions - Circuit integrity - Part 31: Procedures and requirements for fire with shock - Cables of rated voltage up to and including 0,6/1 kV

Specifies the test procedure and gives the performance requirement, including a recommended flame application time, for cables of rated voltage up to and including 0,6/1,0 kV required to maintain circuit integrity when subjected to fire and mechanical shock under specified conditions. It is intended for use when testing cables of greater than 20 mm overall diameter. It describes the means of sample preparation, the continuity checking arrangements, the electrical testing procedure, the method of burning the cables and the method of shock production, and gives requirements for evaluating test results. Applicable to low-voltage power cables, and control cables with a rated voltage. Has the status of a group safety publication in accordance with IEC Guide 104.
