Zoom  Zoom Issue Date:2020-05-07   Browse:546
 
IEC 60331-3 For fire with shock at a temperature and rated voltage – Standard
IEC 60331-3 Tests for electric cables under fire conditions – Circuit integrity – Part 3:Test method for fire with shock at a temperature of at least 830℃ for cables of rated voltage up to and including 0.6/1.0kV tested in a metal enclosure

IEC 60331-3 For fire with shock at a temperature and rated voltage – Scope
This part of IEC 60331 specifies the test method for cables which are required to maintain circuit integrity when tested in a metal enclosure and when subject to fire and mechanical shock under specified conditions.

This document is applicable to cables of rated voltage not exceeding 600 V/1 000 V, including those of rated voltage up to and including 80V, metallic data and telecom cables and optical fibre cables.

It is intended for use when testing cables not greater than 20 mm overall diameter.

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 600V/1000V. 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 60331-3.

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.

IEC 60331-3 For fire with shock at a temperature and rated voltage – Reference standards
IEC 60269-3 Low-voltage fuses - Part 3: Supplementary requirements for fuses for use by unskilled persons (fuses mainly for household or similar application) - Examples of standardized systems of fuses A to F

IEC 60331-1 Tests for electric cables under fire conditions – Circuit integrity – Part 1:Test method for fire with shock at a temperature of at least 830℃ for cables of rated voltage up to and including 0.6/1.0kV and with an overall diameter exceeding 20 mm

IEC 60331-2 Tests for electric cables under fire conditions – Circuit integrity – Part 2:Test method for fire with shock at a temperature of at least 830℃ for cables of rated voltage up to and including 0.6/1.0kV and with an overall diameter not exceeding 20 mm
