IEC 60684-3-281 Ed. 2.0 b:2025

Flexible insulating sleeving - Part 3: Specifications for individual types of sleeving - Sheet 281: Heat-shrinkable, polyolefin sleeving, semiconductive

IEC 60684-3-281 Ed. 2.0 b:2025

IEC 60684-3-281:2025 gives the requirements for two types of heat-shrinkable, polyolefin sleeving, semiconductive, with a nominal shrink ratio of 3:1. This sleeving has been found suitable for use up to temperatures of 100 °C.

Type A: Thin wall - Internal diameter up to 195,0 mm typically.

Type B: Medium wall - Internal diameter up to 120,0 mm typically.

This sleeving is normally supplied in the colour black.

Since these types of sleevings cover a significantly large range of sizes and wall thicknesses, Annex A 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 MV cable accessories and as such, electrical performance will be proven as part of the assembly. Examples of this are described in HD 629 and IEC 60502 (all parts).

This second edition cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:

  • change in volume resistivity requirement to a maximum;
  • change in method to measure resistivity.
