绝缘软套管规范.第3部分:各种型号套管的规范.第209篇:通用阻燃聚烯烃收缩比2:1的热收缩套管

[中文适用范围]： 给出了一种通用、柔性、阻燃、热收缩聚烯烃套管的要求，其标称最小收缩率为 2:1。该套管已被发现适合在高达 125 ℃ 的温度下使用。它通常是一个 [外文原描述]： Gives the requirements for one type of general purpose, flexible, flame retarded, heat-shrinkable polyolefin sleeving with a nominal minimum shrink ratio of 2:1. This sleeving has been found suitable for use at temperatures up to 125 °C. It is normally available in internal diameters up to 102 mm as supplied and in the following colours: black, brown, white, red, yellow, green, blue, orange, violet, grey and yellow/green. Sizes, shrink ratios or colours other than those specifically listed in this standard may be available as custom items. These items are considered to comply with this standard if they comply with the property requirements listed in Tables 2 and 3, excluding dimensions. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. This edition includes the following significant technical changes from the previous edition: it reverts to the metric equivalent of the established imperial size range and aligns the requirements with the 2nd edition of IEC 60684-2.
