This standard is mainly based on the American Society for Testing and Materials standard AM1765-1, which is used for the classification of the standard and is revised by the national standard (/T11853.7-1%31) for the conditions of film pelletization. The main technical differences between this standard and ASTM) 1765-1900 are: One standard adds the relevant gas half-compensation effect and one standard according to the actual situation of the country, and this standard specifies the overall range of the density. One standard stipulates that the overall content of the black content is not more than 10. The main technical differences between this standard and 1453.1391 are as follows: Six types of changes in the formulation of the standard: 5 new types, 1 product cancelled: The technical requirements specified in this standard apply to all types and grades of rubber, used for making carbon black. This standard will replace G1353.7-101 on the date of implementation. This standard is undertaken by the National Petroleum and Chemical Industry Bureau: This standard is drafted by the National Technical Committee for Standardization of Rubber Products and the Technical Committee for Export of Rubber Black. The main drafters of the standard are Xue and Deng Yi. This standard was first issued in May 2011.
