适用范围：The series of International Standards covered by Parts 3-10, 3-21, 3-22, 3-23, 3-24 and 3-25 ofIEC 60332 specifies methods of test for the assessment of vertical flame spread of verticallymounted bunched wires or cables, electrical or optical, under defined conditions.NOTE For the purpose of this standard, the term ‘electric wire or cable’ covers all insulated metallic conductor cables used for the conveyance of energy or signals.The test is intended for type approval testing. The requirements for the selection of cables fortesting are given in annex A. The flame spread is measured as the extent of damage of thecable sample. This procedure may be used to demonstrate the cable’s ability to limit flamespread.This part of IEC 60332 covers category C and relates to cables installed on the test ladder toachieve a nominal total volume of non-metallic material of 1,5 l per metre of test sample. Theflame 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.A recommended performance requirement is given in annex B.
