Abstract

What is IEC 60332‑3‑25 - Best guidelines for testing electric cables and optical fibres about?

IEC 60332‑3‑25 covers category D for methods of test for the assessment of vertical flame spread of vertically mounted bunched wires or cables, electrical or optical, under defined conditions IEC 60332‑3‑25 relates only to small cables of overall diameter 12 mm or smaller and cross-section of 35 mm2 or smaller installed on the test ladder to achieve a nominal total volume of non-metallic material of 0,5 l/m of the test sample. The flame application time is 20 min. The method of mounting uses the front of the standard ladder in touching formation only. The category is intended for use with small cables where very low volumes of non-metallic material are required to be evaluated. Note: For IEC 60332‑3‑25 the term "electric wire or cable" covers all insulated metallic conductor cables used for the conveyance of energy or signals.
