标准摘要
[中文适用范围]: IEC 60684 的这一部分定义了双壁、非阻燃、热收缩聚烯烃套管的要求。该套管适合在高达 110 °C 的温度下使用。套管由半刚性交联材料制成的外层组成。内层是基本上非交联的聚烯烃,其在收缩过程中流动并熔合以提供密封。通常出售的内径最大为 25 毫米,有以下颜色:黑色、白色、红色、黄色、蓝色和半透明。本标准中列出的尺寸或颜色以外的尺寸或颜色可作为定制产品提供。如果这些项目符合表 2、3、4 和 5 中列出的性能要求(不包括尺寸),则视为符合本标准。符合本规范的材料符合既定的性能水平。然而,用户针对特定应用选择材料应基于该应用中足够性能所需的实际要求,而不是仅基于本规范。 [外文原描述]: IEC 60684-3-246:2007 defines requirements for dual wall, non-flame retarded, heat shrinkable, polyolefin sleeving. This sleeving has been found suitable for use up to 110 °C. The sleeving consists of an outer layer made of a semi-rigid cross-linked material. The inner layer is a substantially non-cross-linked polyolefin that flows and fuses during the shrinkage process to provide a seal. The major technical changes with regard to the second edition concern a better alignment with existing national specifications.
