标准摘要
[中文适用范围]: IEC 60684-3 本表给出了四种耐热等级为 105 ℃ 的热收缩、阻燃、有限火灾危险套管的要求,如下所示: A 级:薄壁收缩比 2:1内径最大 102.0 mm B 级:中等壁收缩比 2:1 内径最大 60.0 mm C 级:厚壁收缩比 2:1 内径最大 51.0 mm D 级:中等壁收缩内径比例 3:1,最大 40.0 mm 这些套管通常有以下颜色:黑色、红色、绿色、蓝色、白色、黄色和绿/黄色。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 5、6、7 和 8 中列出的性能要求(不包括尺寸和质量),则应视为符合本标准。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]: Gives the requirements for four types of heat-shrinkable, flame- retarded, limited-fire-hazard sleeving with a thermal endurance rating of 105 °C as shown below: Class A: thin wall, shrink ratio 2:1, internal diameter up to 102,0 mm Class B: medium wall, shrink ratio 2:1, internal diameter up to 60,0 mm Class C: thick wall, shrink ratio 2:1, internal diameter up to 51,0 mm Class D: medium wall, shrink ratio 3:1, internal diameter up to 40,0 mm 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.
