标准摘要
[中文适用范围]： 本部分 IEC 61034 详细说明了用于测量在特定条件下燃烧的电力或光纤电缆烟雾排放的测试设备，例如水平燃烧的少量电缆。在火焰燃烧和阴燃条件下的光透射率（i1）可用于比较不同电缆或符合特定要求。 注：就本标准而言，“电力电缆”一词涵盖所有用于传输能量或信号的绝缘金属导体电缆。 [外文原描述]： IEC 61034-1:2005+A1:2013+A2:2019 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), its amendment 1 (2013) and its amendment 2 (2019). Therefore, no need to order amendment in addition to this publication.
