IEC 61034-2:20 05+A1:2013提供了用于测量在规定条件下燃烧的电缆发出的烟雾密度的测试程序的细节。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推荐要求。与上一版相比的主要变化如下: a)包括直径低至1mm的电缆； b)包括非圆形电缆； c)增加了关于测试直径超过80毫米的电缆的指南； d)描述测试报告的要素； e)增加其他参数计算指南 消防安全工程目的； f)消除与等效CENELEC工作的微小差异 允许与该机构平行投票。根据IEC指南104，具有团体安全出版物的状态。 本合并版本由第三版（2005年）组成 及其修正案1（2013年）。因此，无须在 本出版物的补充。

IEC 61034-2:2005+A1:2013 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. This consolidated version consists of the third edition (2005) and its amendment 1 (2013). Therefore, no need to order amendment in addition to this publication.
