IEC 61034-1:20 05+A1:2013提供了测试设备的细节，该测试设备用于测量当电缆或光纤电缆在规定条件下燃烧时的烟雾排放，例如，一些电缆水平燃烧。燃烧和闷烧条件下的透光率（lt）可用作比较不同电缆或符合特定要求的手段。注:就本标准而言，术语“电缆” 涵盖用于 能量或信号的传递。相对于前一版本的主要变化如下:a)更精确地定义了通风筛和腔室孔口； b)对被测电缆的支撑的更精确定义； c)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 61034-1:2005+A1:2013 Provides details of the test apparatus to be used for measuring smoke emission when electric or optical fibre cables are burnt under defined conditions, for example, a few cables burnt horizontally. The light transmittance (lt) under flaming combustion and smouldering conditions can be used as a means of comparing different cables or complying with specific requirements. NOTE: For the purposes of this standard, the term "electric cable" covers all insulated metallic conductor cables used for the conveyance of energy or signals. The principal changes with respect to the previous edition are as follows:
a) closer definition of the draught screen and the chamber orifices;
b) closer definition of the support for the cable(s) under test;
c) 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.
