+AMD1:2013+AMD2:2019 CSV 在规定条件下燃烧电缆的烟密度测量.第2部分:试验程序和要求

[中文适用范围]： This part of IEC 61034 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. La présente partie de l'IEC 61034 fournit des détails de la procédure d'essai à employer pour la mesure de la densité des fumées émises par des câbles brûlant dans des conditions définies. Elle décrit les méthodes de préparation et d'assemblage des câbles en essais, la méthode d'inflammation des câbles, et donne des recommandations pour les exigences relatives à l'évaluation des résultats d'essais. [外文原描述]： IEC 61034-2:2005+A1:2013+A2:2019 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. 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.
