28、or individual types of sleeving (IEC 60684-3) This standard comprises one of the sheets of Part 3 as follows: Sheet 280: Heat-shrinkable, polyolefin sleeving, anti-tracking BS EN 60684-3-280:2010 BS EN 60684-3-280:2010+A1:201460684-3-280 IEC:2010+A1:2014 6 60684-3-280 IEC:2010 FLEXIBLE INSULATING SL
29、EEVING Part 3: Specifications for individual types of sleeving Sheet 280: Heat-shrinkable, polyolefin sleeving, anti-tracking 1 Scope This part of IEC 60684 gives the requirements for heat-shrinkable, polyolefin sleeving, anti-tracking with a nominal shrink ratio of 3:1. This sleeving has been found
30、 suitable for use at temperatures up to 100 C. Typically: medium wall, internal diameter up to 110 mm. These sleevings are normally supplied in the colours red or brown. Since these types of sleevings cover a significantly large range of sizes and wall thicknesses, Table A.1 in this standard provide
31、s guidance on 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, the selection of a material by a user for a specific application should be based on the actual
32、 requirements necessary for adequate performance in that application and not based on this specification alone. This sleeving is designed to be used in medium voltage cable accessories and as such electrical performance must be proven as part of the assembly. Examples of this are described in HD 629
33、 and IEC 60502 series. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

NOTE This information is for labelling only, in accordance with IEC 60684-1. 4 Conditions of test Unless otherwise specified, the sleeving shall be shrunk in a forced air circulation oven for (10 1) min at 200 C 3 K prior to testing. 5 Requirements In addition to the general requirements give
40、n in IEC 60684-1, the sleeving shall comply with the requirements of Tables 1, 2, 3, and 4 where applicable. 6 Sleeving conformance Conformance to the requirements of this specification shall normally be based on the results from typical sizes Recovered ID 20 mm - 30 mm BS EN 60684-3-280:2010 BS EN
