IEC 60811-601:2012 specifies the test procedure for measuring the drop point of filling compounds. IEC 60811-601:2012 cancels and replaces Clause 4 of IEC 60811-5-1:1990, which is withdrawn.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.
