What is ASTM certification? Mainly to study and solve the test method problems of steel and other materials. The English name is American Society of Testing, and the initials are abbreviated as ASTM. Chinese means American Society for Testing and Materials. ASTM certification includes the research and development of material specifications and test method standards, as well as the characteristics and performance standards of various materials, products, systems, and service items, as well as test methods, procedures and other standards. In addition to child safety seats, its main testing items include ASTM certification for baby products, ASTM certification for textile materials, ASTM certification for doll clothing, and ASTM certification for plastic toys.
ASTM safety standards are compulsory certification standards in the United States. In the past few years, the global industry has undergone rapid development and tremendous changes. Countries and regions around the world, led by the European Union and the United States, have begun to amend relevant laws and standards. Among them, the European Union EN71 The new directive 2009/48/EC has officially entered into force, and the relevant laws and standards are also undergoing changes.
ASTM certification standard numbering method
The ASTM standard number format is: standard code + letter classification code + standard serial number + year of establishment + standard English name.
For example: ASTM A 221M 95 (1997) Standard Specification for Cold Alloy Steel
ASTM stands for standard code;
A stands for letter classification code;
221M represents the standard serial number;
95 (1997) year of formulation;
The name of the representative standard of the cold alloy rigid material standard specification
