[中文适用范围]： This Part 508 of IEC 60811 gives the procedure for a pressure test at high temperature, which typically applies to thermoplastic compounds used for insulating and sheathing materials. NOTE 1 The method is principally intended for thermoplastic materials, but may be used for cross-linked materials when specifically required by the relevant cable standard. NOTE 2 The test method is not recommended for thicknesses below 0.7 mm. [外文原描述]： IEC 60811-508:2012+A1:2017 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 IEC 60811-508:2012 cancels and replaces Clause 8 of IEC 60811-3-1:1985, which is withdrawn.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 IEC 60811-100:2012. This consolidated version consists of the first edition (2012) and its amendment 1 (2017). Therefore, no need to order amendment in addition to this publication.
