This part of IEC 60684 gives the requirements for two types of heat-shrinkable@ polyolefin sleeving@ dual wall@ not flame retarded with a nominal shrink ratio of 3:1. This sleeving has been found suitable for use at temperatures of up to 100 ?? Type A : Medium wall@ internal diameter up to 200@0 mm typically Type B : Thick wall@ internal diameter up to 200@0 mm typically These sleevings are normally supplied in colour black. Since these types of sleevings cover a significantly large range of sizes and wall thicknesses@ Tables A.1 and A.2 provide a guide to the range of sizes available. The actual size shall be agreed between the user and 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 should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone.
