Tests on electric and optical fibre cables under fire conditions - Test for vertical flame spread of vertically-mounted bunched wires or cables. Category B1 Scope The series of International standards covered by Parts 3 10, 3 21, 3 22, 3 23, 3 24 and 3 25 of IEC 60332 specifies methods of test for the assessment of vertical flame spread of vertically mounted 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
