IEC 60332-3-22 Ed. 2.0 b:2018

Tests on electric cables under fire conditions - Part 3-22: Test for vertical flame spread of vertically-mounted bunched wires or cables - Category A

IEC 60332-3-22:2018 covers category A 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 7 l/m of test sample. The flame application time is 40 min.

The method of mounting uses the front of the ladder, a standard or wide ladder being used for cables having a conductor cross-section greater than 35 mm2 according to the number of test pieces required, and a standard ladder for conductor cross-sections 35 mm2 and smaller.

The category is intended for general use where high 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.

This second edition cancels and replaces the first edition published in 2000 and Amendment 1:2008. This edition constitutes a technical revision and includes the following significant technical changes with respect to the previous edition:

  • a) adjustments have been made to the title, and elsewhere, to emphasise the standard is applicable to optical fibre cables as well as metallic conductor types;
  • b) details of the way in which cables are mounted on the ladder have been better defined in order to improve repeatability and reproducibility.

It has the status of a group safety publication in accordance with IEC Guide 104.
