标准摘要
[中文适用范围]： “IEC 61156 的这一部分描述了对称双绞线/四绞线电缆，主要用于 ISO/IEC 11801 和 ISO/IEC 24702 中定义的水平地板布线。注 ISO/IEC 24702 中提出了环境分类，在四个领域分为三个严重级别：机械@入口@气候@和电磁；因此@以表格形式@它们被称为““MICE表””。此空白详细规范包括额外推荐的环境特征和严重性，这些特征和严重性源自指定的环境分类各种环境的布线。空白详细规范确定了描述数字通信对称双绞线/四线电缆的详细规范的布局和风格。详细规范@基于空白详细规范@可以由国家组织@制造商或用户准备”。 [外文原描述]： IEC 61156-5-1:2009(E) describes symmetrical pair/quad cables intended primarily for horizontal floor cabling as defined in ISO/IEC 11801 and ISO/IEC 24702. It includes additional recommended environmental characteristics and severities which are derived from the environmental classifications that are specified for cabling for various environments. This edition constitutes a technical revision and includes the following significant technical changes with respect to the previous edition: - new requirements for new cables Cat6A and Cat7A; - revised requirements and tests for the cables. This publication is to be read in conjunction with IEC 61156-1:2007 and IEC 61156-5:2009 .
