What is ASTM organization?

ASTM is an acronym for the American Society for Testing and Materials, formerly known as the International Association for Testing Materials (IATM). In the 1880s, some people proposed the establishment of a technical committee system, the technical committee to organize representatives of all aspects of the technical symposium, to discuss and resolve the material specifications, test procedures and other aspects of the dispute. IATM first meeting was held in Europe in 1882, the meeting formed a working committee. At that time, the main research to solve the problem of steel and other materials testing methods. 1902 in the International Association for Testing of Materials chapter of the fifth annual meeting, declared the U.S. chapter formally independent, named the American Society for Testing Materials (American Society for Testing Materials). With the continuous expansion and development of its business scope, the Society's work is not only the center of the research and development of material specifications and test method standards, but also includes a variety of materials, products, systems, services, characteristics and performance standards, as well as test methods, procedures and other standards. 1961, the organization will be changed to the name of the extension of the United States Materials and Testing Association (American Society for Testing and Materials, ASTM) American Society for Testing and Materials, ASTM).

ASTM is one of the oldest and largest non-profit standards organizations in the United States. After a century of development, ASTM now has 33,669 (individual and group) members, of which 22,396 members of the main committees in its various committees to serve as a technical expert work. ASTM's technical committees under the *** have 2004 technical subcommittees. There are 105,817 organizations that participate in the development of ASTM standards, with the primary mission of developing standards for properties and performance of materials, products, systems, and services, standards for test methods and procedures, and promoting the development and dissemination of related knowledge.

Types of ASTM standards

1. test method (Test Method): a defined process of identifying, measuring, and evaluating one or more properties, characteristics, or performance of a material, product, system, or service that produces test results.

2. Standard Specification (Standard Specification): materials, products, systems or services to meet a set of requirements for the precise description, but also how to meet each requirement to determine the process.

3. Standard procedures (Practice): the implementation of one or more specific operations or functions that do not produce test results to determine the process.

4. standard terminology (Terminology): a document consisting of terms, definitions of terms, descriptions of terms, symbols, abbreviations and so on.

5. Standard Guidance (Guidance): a series of options or instructions that do not recommend a particular course of action.

6. Standard Classification (Standard Classification): according to the same characteristics of the material, product, system or service system grouping.
