IEC 60811-505:2012给出了在低温下对挤压绝缘材料和护套进行伸长率测试的程序。IEC 60811-505:2012取消并取代已撤回的IEC 60811-1-4:19 85的8.3和8.4。IEC 60811-100:2012附录A中显示了替换件的全部详细信息。与上一版本相比没有具体的技术变化，但请参见IEC 60811-100:2012的前言。 本出版物应与IEC 60811-100:2012一起阅读。

IEC 60811-505:2012 gives the procedure for performing elongation tests at low temperature on extruded insulations and sheaths. IEC 60811-505:2012 cancels and replaces 8.3 and 8.4 of IEC 60811-1-4:1985, which is withdrawn.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 IEC 60811-100:2012.
