ASTM International (ASTM) is the recognized leader in the development and delivery of international voluntary consensus standards. Today, some 12,000 ASTM testing standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. The standards produced by ASTM International fall into six categories:

• Standard Specifications, that defines the requirements to be satisfied by subject of the standard.
• Standard, Test method that defines the way a test is performed and the precision of the result. The result of the test may be used to assess compliance with a Standard Specification.
• Standard Practice that defines a sequence of operations that, unlike a Standard Test Method, does not produce a result.
• Standard Guide that provides an organized collection of information or series of options that does not recommend a specific course of action
• Standard Classification, that provides an arrangement or division of materials, products, systems, or services into groups based on similar characteristics such as origin, composition, properties, or use.
• Terminology Standard, that provides agreed definitions of terms used in the other standards.

The quality of ASTM testing standards is such that they are frequently used worldwide.
