本文件规定了热收缩半柔性聚偏二乙烯所需的特性 工作温度在-55°C和150°C之间的飞机电气系统中使用的套管。该套管基本上是透明的，但可能是有色的。它具有半柔性、韧性和耐磨性，适用于需要应变消除和机械保护的地方，或需要透明性能的地方。 它不适用于可能受到磷酸酯基液压油污染的地方。 这些套管的内径通常为25.4 mm，收缩比为2:1。 除本标准中特别列出的尺寸外，还可以提供其他尺寸。这些项目应: 如果符合表2所列的性能要求，则视为符合本标准， 3和4，尺寸和质量除外。交叉引用:IEC 60684-1EN 4708-001IEC 60757ISO 846IEC 60684- 2ISO 1817EN 3909购买本文件时提供的所有当前修订版均包含在购买本文件中。

This document specifies the required characteristics for a heat-shrinkable, semi-flexible polyvinylidene sleeving for use in aircraft electrical systems at operating temperatures between – 55 °C and 150 °C. This sleeving is basically transparent, but may be tinted. It is semi-flexible tough and abrasion resistant, and is suitable for use where strain relief and mechanical protection are required, or where their transparent properties are desirable. It is not suitable for use where contamination from phosphate ester based hydraulic fluid is possible. These sleevings are normally supplied with internal diameters up to 25,4 mm for shrink ratios of 2:1. Sizes other than those specifically listed in this standard may be available. These items shall be considered to comply with this standard if they comply with the property requirements listed in Tables 2, 3 and 4 except for dimensions and mass.Cross References:IEC 60684-1EN 4708-001IEC 60757ISO 846IEC 60684-2ISO 1817EN 3909All current amendments available at time of purchase are included with the purchase of this document.
