This part of IEC 60331 specifies the test method for cables which are required to maintain circuit integrity when subject to fire and mechanical shock under specified conditions.<\/p>\n

This document is applicable to cables of rated voltage not exceeding 600 V\/1 000 V, including those of rated voltage below 80 V, metallic data and telecom cables and optical fibre cables.<\/p>\n

It is intended for use when testing cables of greater than 20 mm overall diameter.<\/p>\n

Cables of smaller diameter are intended to be tested using the apparatus, procedure and requirements of IEC 60331-2.<\/p>\n

This document includes details for the specific point of failure, continuity checking arrangement, test sample, test procedure and test report relevant to electric power and control cables with rated voltage up to and including 600 V\/1 000 V. Details for the specific point of failure, continuity checking arrangement, test sample, test procedure and test report relevant to metallic data and telecom cables and optical fibre cables are not given by IEC 60331-1.<\/p>\n

Although the scope is restricted to cables with rated voltage up to and including 0,6\/1,0 kV, the procedure can be used, with the agreement of the manufacturer and the purchaser, for cables with rated voltage up to and including 1,8\/3 (3,3) kV, provided that suitable fuses are used.<\/p>\n

Annex A provides the method of verification of the burner and control system used for the test.<\/p>\n

Requirements are stated for an identification that may optionally be marked on the cable to signify compliance with this document.<\/p>\n

CAUTION \u2013 The test given in this standard may involve the use of dangerous voltages and temperatures. Suitable precautions should be taken against the risk of shock, burning, fire and explosion that may be involved, and against any noxious fumes that may be produced.<\/b><\/p>\n
