BS EN 4708-104:2017规定了热收缩半刚性材料所需的特性 工作温度在-55°C之间的飞机电气系统用聚偏二乙烯套管 和175°C。这种袖子基本上是透明的，但可能是有色的。它具有半刚性、韧性和耐磨性， 适用于需要应变消除和机械保护的地方，或 透明性能是理想的。这些套管的内径通常为25.4 mm，收缩率为2: 1.除本欧洲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: 如果符合所列的性能要求，则视为符合本欧洲标准 在表2、3和4中，尺寸和质量除外。交叉引用:EN 60684-2（IEC 60684-2:2011）ASIEC 60684-1:2003EN 60684-1（IEC 60684-1:2003）ASIEC 60757:1983ISO 846:1997IEC 60684-2:2011ISO 1817:2005MIL-PRF-87937EN ISO 846:1997EN 4708-001EN 3909HD 457 S1:1985AMS 1476B:2004购买本文件时可提供的所有当前修改件均包含在购买本文件中。

BS EN 4708-104:2017 specifies the required characteristics for a heat-shrinkable, semi-rigid polyvinylidene sleeving for use in aircraft electrical systems at operating temperatures between - 55 °C and 175 °C.This sleeving is basically transparent, but may be tinted. It is semi-rigid, tough and abrasion resistant, and is suitable for use where strain relief and mechanical protection are required, or where their transparent properties are desirable.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 European Standard may be available. These items shall be considered to comply with this European Standard if they comply with the property requirements listed in Tables 2, 3 and 4 except for dimensions and mass.Cross References:EN 60684-2 (IEC 60684-2:2011) ASIEC 60684-1:2003EN 60684-1 (IEC 60684-1:2003) ASIEC 60757:1983ISO 846:1997IEC 60684-2:2011ISO 1817:2005MIL-PRF-87937EN ISO 846:1997EN 4708-001EN 3909HD 457 S1:1985AMS 1476B:2004All current amendments available at time of purchase are included with the purchase of this document.
