着火条件下电缆和光缆的试验第3-10部分:垂直安装的成束电线或电缆的垂直火焰蔓延试验仪器

[中文适用范围]： 本部分 IEC 60332 详细说明了用于评估在特定条件下垂直安装的成束电线或电缆（电气或光学）垂直火焰蔓延的测试方法的设备及其布置和校准。 注：为了本文件的目的，术语“电线或电缆”包括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 60332-3-10:2018 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60332-3-10:2018 details the apparatus and its arrangement and calibration for methods of test for the assessment of vertical flame spread of vertically mounted bunched wires or cables, electrical or optical, under defined conditions. This second edition cancels and replaces the first edition published in 2000 and Amendment 1:2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) adjustments have been made to the title, and elsewhere, to emphasise the standard is applicable to optical fibre cables as well as metallic conductor types; b) details of the way in which cables are mounted on the ladder have been better defined in order to improve repeatability and reproducibility; c) the connection of the venturi mixer to the burner is better defined. It has the status of a group safety publication in accordance with IEC Guide 104. The contents of the corrigendum of October 2018 have been included in this copy.
