IEC 60811-511:2012 describes the procedure for the measurement of the melt flow index for polyethylene compounds. IEC 60811-511:2012 cancels and replaces Clause 10 of IEC 60811-4-1:2004, which is withdrawn.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 /2.
