IEC 60811-510:2012 specifies the test method for a wrapping test after thermal ageing in air. This test method applies specifically to polyolefin insulation in communication cables. This test is intended for polyolefin insulations of unfilled cables and of dry cores for filled cables, where the insulation has a wall thickness of less than or equal to 0,8 mm. IEC 60811-510:2012 cancels and replaces Clause 10 of IEC 60811-4-2:2004, which is withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012. There are no specific technical changes with respect to the previous edition, but see the Foreword to IEC 60811-100:2012.This publication is to be read in conjunction with a href='http://webstore.iec.ch/webstore/webstore.nsf/ArtNum_PK/46164'IEC 60811-100:2012/a.
