IEC 60684-3-216:2019 RLV包含官方IEC国际标准及其红线版本。Redline版本不是官方文档，它只有英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC 60684-3-216:2019给出了四种热收缩、阻燃、有限火灾危险套管的要求，其耐热等级为105°C，如下所示。 A级:薄壁收缩比2:1内径可达102.0 mm B级:中等壁收缩率2:1内径至60.0 mm C级:厚壁收缩比2:1内径达51.0 mm D类:中等壁收缩率3:1内径至40.0 mm 这些套管通常有以下颜色:黑色、红色、绿色、蓝色、白色、黄色和绿色/黄色。本文档中列出的尺寸或颜色以外的尺寸或颜色可作为定制项目。如果这些项目符合表5、表6、表7和表8中列出的性能要求，不包括尺寸和质量，则视为符合本文件。符合本规范的材料符合既定的性能水平。然而，用户对特定应用的材料的选择将基于该应用中足够性能所必需的实际要求，而不是仅基于本说明书。本第二版取消并取代了2001年出版的第一版、修正案1:20 05和修正案2:20 13。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:1.套管在强制空气循环烘箱中收缩(5±1)min的温度已从(150±5)℃提高到(200±5)℃。 关键词:电气用柔性绝缘套管

IEC 60684-3-216:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is not an official document, it is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

IEC 60684-3-216: 2019 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
These sleevings are normally supplied in the following colours: black, red, green, blue, white, yellow and green/yellow. Sizes or colours other than those listed in this document are available as custom items. These items are considered to comply with this document if they comply with the property requirements listed in Tables 5, 6, 7 and 8, excluding dimensions and mass. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application will be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. This second edition cancels and replaces the first edition published in 2001, Amendment 1:2005 and Amendment 2:2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
1. the temperature at which the sleeving is shrunk in a forced-air circulation oven for (5 ± 1) min has been increased from (150 ± 5) °C to (200 ± 5) °C.
