22、hods of test (IEC 60684-2) Part 3: Specifications for individual types of sleeving (IEC 60684-3) This standard comprises one of the sheets of Part 3 as follows: Sheet 282: Heat-shrinkable, polyolefin sleeving Stress control BS EN 60684-3-282:2010 6 60684-3-282 IEC:2010 FLEXIBLE INSULATING SLEEVING P
23、art 3: Specifications for individual types of sleeving Sheet 282: Heat-shrinkable, polyolefin sleeving Stress control 1 Scope This part of IEC 60684 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
24、. 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 These sleevings are normally supplied in colour black. Since these types of sleevings cover a sign
25、ificantly large range of sizes and wall thicknesses, Tables A.1 and A.2 in this standard provides guidance to the range of sizes available. The actual size shall be agreed between the user and the supplier. Materials which conform to this specification meet established levels of performance. However
26、, 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. This sleeving is designed to be used in MV cable accessories and as such electrical performa
27、nce must be proven as part of the assembly. Examples of this are described in HD 629 and the IEC 60502 series. 2 Normative references The following referenced documents are indispensable for the application of this document.
