IEC 60684-3-280:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 69684-3-280:2019 gives the requirements for heat-shrinkable, polyolefin sleeving, anti-tracking with a nominal shrink ratio of 3:1. This sleeving has been found suitable for use at temperatures up to 100 °C. Typically: medium wall, internal diameter up to 110 mm. This sleeving is normally supplied in the colours red or brown. Since these types of sleeving cover a significantly large range of sizes and wall thicknesses, Annex A (Table A.1) provides guidance on the range of sizes available. The actual size will 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 will 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 medium voltage cable accessories and as such electrical performance willbe proven as part of the assembly. Examples of this are described in HD 629.1 and IEC 60502 (all parts). This second edition cancels and replaces the first edition published in 2010 and Amendment 1:2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - change of moulded plaque thickness for resistance to tracking and weathering tests to (6 ± 0,5) mm.
