IEC 60811-406:2012 gives the procedure for evaluating the resistance to stress cracking of polyethylene and polypropylene compounds which are typically used for communication and optical fibre cables. IEC 60811-406:2012 cancels and replaces Clause 8 of IEC 60811-4-1:2004, which is withdrawn.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 IEC 60811-100:2012.
