IEC 60684-3-280:2019作为IEC 60684-3-280:2019 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 69684-3-280:2019给出了标称收缩比为3:1的热收缩聚烯烃套管、防跟踪的要求。已经发现这种套管适合在高达100℃的温度下使用。通常:中等壁，内径高达110毫米。这种套管通常有红色或棕色。由于这些类型的套管涵盖了非常大的尺寸和壁厚范围，附录A（表A.1）提供了有关可用尺寸范围的指导。实际尺寸将由用户和供应商商定。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。该套管设计用于中压电缆附件，因此电气性能将作为组件的一部分得到验证。HD 629.1和IEC 60502（所有部分）中描述了这方面的示例。本第二版取消并取代了2010年出版的第一版和修正案1:20 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: -将耐跟踪和耐风化试验的模制饰板厚度变更为（6±0.5）mm。 关键词:热收缩聚烯烃套管防跟踪

IEC 60684-3-280:2019 is available as IEC 60684-3-280:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 69684-3-280:2019 gives the requirements for heat-shrinkable, polyolefin sleeving, anti-tracking with a nominal shrink ratio of 3:1. This sleeving has been found suitable for use at temperatures up to 100 °C. Typically: medium wall, internal diameter up to 110 mm. This sleeving is normally supplied in the colours red or brown. Since these types of sleeving cover a significantly large range of sizes and wall thicknesses, Annex A (Table A.1) provides guidance on the range of sizes available. The actual size will be agreed between the user and the supplier. 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 sleeving is designed to be used in medium voltage cable accessories and as such electrical performance willbe proven as part of the assembly. Examples of this are described in HD 629.1 and IEC 60502 (all parts). This second edition cancels and replaces the first edition published in 2010 and Amendment 1:2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- change of moulded plaque thickness for resistance to tracking and weathering tests to (6 ± 0,5) mm.
