The main differences between this standard and H/12471-1993 are: the standard name has been connected, and the applicable scope of the standard has been expanded from one product to several products of the same category. The "materials and machine tools" part has been revised to "materials", and the coating has been retained as the main material part. The technical indicators of the coating have been adjusted: (1) The material part is required to meet the actual needs of the product, and the technical indicators are divided into three types to meet the actual needs of the product. The sample part has been added with detailed information on the sample preparation. The control equipment and test recording equipment have been further clarified. The degree of discharge rate and test conditions of the graded electric discharge have been clarified. The test endpoint of extended chemical life has been redefined. The average width or sample point has been redefined. The enterprise has adjusted the inspection rules and added the judgment rules of the test results. The safety requirements of the document have been clarified. This standard will be implemented from the date of IG/271-19.
