30、lyolefin sleeving, dual wall, not flame retarded, thick and medium wall 1 Scope 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 temp

31、eratures of up to 100 C. 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 thicknes

32、ses, 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 shou

33、ld be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. 2 Normative references The following referenced documents are indispensable for the application of this document.
