Many users, especially the big three automakers—Chrysler, Ford, and General Motors, want to select materials for a certain purpose, and want to have data that are comparable and comparable. These users have realized that it is necessary to reduce the consumption of raw materials. As well as carrying out dual tests (using ISO and ASTM standard tests, respectively) on the consumption of energy and financial resources, only the pace of conversion to ISO/IEC standards was accelerated. Therefore, a few years ago, ASTM had already begun the work of converting to ISO/IEC.
1. In December 1994, the ASTM D20 Plastics Committee appointed a dedicated agency responsible for the development of coherent policies to increase the coordination of transformation work among the subcommittees, and that the conversion work was not limited to the ASTM standard. Attach the corresponding description of ISO.
2. Since 1995, ASTM has developed and revised a number of ASTM standards that use ISO standards. For example, in 1996, ASTM D1999 “Guide to selection of test specimens and test parameters for international trade” was released, which is dedicated to international trade. The specimens and test parameters based on the ISO test method.
3. In 1996, ASTM D 20 Plastics Committee put forward its "unification" process, namely: (1) Voting ISO documents as equivalent ASTM documents; (2) Adding ISO documents as a separate step within ASTM documents; (3) When necessary, divide the ASTM standards into two standards to make the standards as close as possible to the ISO standards
