着火条件下电缆和光缆的试验第1-2部分:单根绝缘电线或电缆的垂直火焰传播试验1kW预混合火焰的程序

[中文适用范围]： 本部分IEC 60332规定了在火灾条件下使用1 kW预混火焰测试单个垂直绝缘导体或电缆或光缆垂直火焰蔓延抗性的程序。设备描述见IEC 60332-1-1。 注1：如果需要，可以同时进行IEC 60332-1-2和IEC 60332-1-3的测试。 本组安全出版物主要用作产品安全标准，用于范围中提到的产品，但也适用于技术委员会根据IEC指南104和ISO/IEC指南51的原则，为与范围中提到的产品相似的产品制定标准。 注2：对单个绝缘导体或电缆或光缆进行此测试方法，当该导体或电缆或光缆与其他电缆一起安装时，不能提供符合相关标准中火灾传播要求的情况。（参见IEC 60332-3系列）。 技术委员会的职责之一是在适用的情况下，在制定其出版物时使用基本安全出版物和/或组安全出版物。 [外文原描述]： IEC 60332‑1‑2:2025 specifies the procedure for testing the resistance to vertical flame propagation for a single vertical electrical insulated conductor or cable, or optical fibre cable, under fire conditions using a 1 kW pre-mixed flame. The apparatus is described in IEC 60332‑1‑1. NOTE 1 Testing to IEC 60332‑1‑2 can be performed simultaneously with that to IEC 60332‑1‑3, if required. This group safety publication focusing on test method(s) is primarily intended to be used as a product safety standard for the products mentioned in the scope, but is also intended to be used by technical committees in the preparation of standards for products similar to those mentioned in the scope of this group safety publication, in accordance with the principles laid down in IEC Guide 104 and lSO/lEC Guide 51. NOTE 2 The performing of this test method on a single insulated conductor or cable or optical fibre cable does not provide compliance with fire propagation requirements in relevant standards in the case that the single insulated conductor or cable or optical fibre cable is installed with or amongst other cables as a group. (See the IEC 60332‑3 series). One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications and/or group safety publications in the preparation of its publications.
