IEC 60684-3-282:2025 gives the requirements for two types of heat-shrinkable, polyolefin sleeving, stress control, not flame retarded, with a nominal shrink ratio up to 3:1.
This sleeving has been found suitable for use up to temperatures of 100 °C.
Type A: Medium wall Internal diameter up to 65,0 mm typically
Type B: Thick wall Internal diameter up to 95,0 mm typically
Since these types of sleevings cover a significantly large range of sizes and wall thicknesses, Annex A provides guidance to the range of sizes available. The actual size will be agreed between the user and the supplier.
