IEC 60811-508:2012 gives the procedure for a pressure test at high temperature, which typically applies to thermoplastic compounds used for insulating and sheathing materials. IEC 60811-508:2012 cancels and replaces Clause 8 of IEC 60811-3-1:1985, which is withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012. Significant technical changes with respect to the previous edition are as follows: – re-statement of oven characteristics, especially relating to anti-vibration and to temperature control; – enhanced detail as to the preparations and testing of flat cables; – enhanced detail as to thickness and dimensional measurements. See also the Foreword to IEC 60811-100:2012. This publication is to be read in conjunction with /2.
