IEC 60811-402:2012 describes water absorption tests which typically apply to cross-linked and thermoplastic compounds used for insulating and sheathing materials. IEC 60811-402:2012 cancels and replaces Clause 9 of IEC 60811-1-3:1993, which is withdrawn.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.
