Organization: IEC
Publication Date: 1 July 2018
Status: active
Page Count: 32
ICS Code (Cables): 29.060.20
ICS Code (Ignitability and burning behaviour of materials and products): 13.220.40
ICS Code (Electrical engineering in general): 29.020
scope:

This part of IEC 60332 covers category C for methods of test for the assessment of vertical flame spread of vertically mounted bunched wires or cables, electrical or optical, under defined conditions.

This document relates to cables installed on the test ladder to achieve a nominal total volume of non-metallic material of 1,5 l/m of test sample. The flame application time is 20 min. The method of mounting uses the front of the standard ladder. The category is intended for general use where low volumes of non-metallic material are required to be evaluated.

The test is intended for type approval testing. The requirements for the selection of cables for testing are given in Annex A. The flame spread is measured as the extent of damage of the cable sample. This procedure can be used to demonstrate the cable's ability to limit flame spread.

A recommended performance requirement is given in Annex B.

NOTE For the purposes of this document the term "electric wire or cable" covers all insulated metallic conductor cables used for the conveyance of energy or signals.
