24、84-2) Part 3: Specifications for individual types of sleeving (IEC 60684-3) This standard gives one of the sheets comprising Part 3 as follows: Sheet 214: Heat-shrinkable, polyolefin sleeving, not flame retarded, thick and medium wall.

25、G SLEEVING Part 3: Specifications for individual types of sleeving Sheet 214: Heat-shrinkable, polyolefin sleeving, not flame retarded, thick and medium wall 1 Scope This standard gives the requirements for two types of heat-shrinkable, polyolefin sleeving, not flame retarded, thick and medium wall
26、with a nominal shrink ratio of 3:1. This sleeving has been found suitable for use at temperatures of up to 100 C. Type A: Medium wall internal diameter up to 200 mm typically. Type B: Thick wall internal diameter up to 200 mm typically. These sleevings are normally supplied in colour black. Since th
27、ese types of sleevings cover a significantly large range of sizes and wall thicknesses, Tables A.1 and A.2 of this document provides a guide to the range of sizes available. The actual size will be agreed between the user and supplier. Materials which conform to this specification meet established l
28、evels 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. 2 Normative references The following documents, in whole or in
