American ASTM
The predecessor of ASTM was the International Association for Testing Materials (IATM).
In the 1880s, in order to resolve the opinions and disagreements between buyers and suppliers in the process of purchasing and selling industrial materials, some proposed the establishment of a technical committee system. The technical committee organized representatives from various aspects to participate in technical symposiums to discuss and resolve disputes related to material specifications, testing procedures, and other aspects.
ASTM is one of the oldest and largest non-profit standard academic groups in the United States. After a century of development, ASTM currently has 33669 (individual and group) members, of which 22396 main committee members serve as technical experts in its various committees. There are a total of 2004 technical subcommittees under the ASTM Technical Committee. 105817 units participated in the development of ASTM standards, with the main task of developing characteristic and performance standards, test methods and procedural standards for materials, products, systems, and services, and promoting the development and promotion of relevant knowledge.
1 ASTM Standard Classification
There are six types of ASTM standards.
(1) Standard Test Method is a prescribed procedure used to identify, test, and evaluate the quality, characteristics, and parameters of materials, products, systems, or services.
(2) A Standard Specification sets out technical requirements for materials, products, systems, or projects and provides specific explanations. It also proposes the procedures that should be adopted to meet the technical requirements.
(3) Standard Practice is a program that provides instructions for one or more specific operations or functions, but does not produce test results.
(4) Standard Terminology describes or defines nouns, and explains symbols, abbreviations, and acronyms.
(5) The Standard Guide provides a selection or explanation of usage for a series, but does not introduce specific implementation methods.
(6) Standard classification (Class. classification) It distinguishes and categorizes materials, products, systems, or specific services based on their source, composition, performance, or use
