提供了用于测量电缆在规定条件下燃烧时排放的烟雾密度的测试程序的详细信息。它描述了准备和组装测试用电缆的方法、燃烧电缆的方法，并给出了评估测试结果的建议要求。 与上一版相比，主要变化如下: a） 包括直径小于等于1mm的电缆； b） 包括非圆形电缆； c） 增加了直径大于80 mm的电缆测试指南； d） 测试报告要素的描述； e） 增加消防安全工程其他参数的计算指南； f） 通过等效的CENELEC工作消除细微差异，以允许与该机构进行平行投票。 具有符合IEC指南104的集团安全出版物状态。 本副本包含2006年9月勘误表的内容。

Provides details of the test procedure to be employed for the measurement of the density of smoke emitted from cables burning under defined conditions. It describes the means of preparing and assembling cables for test, the method of burning the cables, and gives recommended requirements for evaluating test results. The principal changes with respect to the previous edition are as follows: a) inclusion of cables down to 1 mm diameter; b) inclusion of non-circular cables; c) addition of guidance on testing cables above 80 mm diameter; d) delineation of elements of the test report; e) addition of guidance on the calculation for other parameters for fire safety engineering purposes; f) removal of minor differences with equivalent CENELEC work to allow parallel voting with that body. Has the status of a group safety publication in accordance with IEC Guide 104. The contents of the corrigendum of September 2006 have been included in this copy.
