IEC 60811-607:2012 specifies test methods for carbon black dispersion that are applicable specifically to PE and PP compounds, including cellular compounds and foam skin for insulation. IEC 60811-607:2012 cancels and replaces Clause 13 of IEC 60811-4-1:2004, which is withdrawn.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.
