The Differences Between the 6 Types of ASTM Standards?

Test Method Standards define the procedures for generating test results. These include identifying, measuring, and evaluating one or more qualities, characteristics, or properties. A practice Method Standard is a set of instructions for performing one or more operations that do not result in a test result. Application, assessment, cleaning, collection, inspection, preparation, sampling, and training are examples.

Specifications Standards are requirements that a material, product, system, or service must meet. The specification identifies test methods for determining whether each requirement is met. These requirements can include physical, mechanical, or chemical properties, and safety, quality or performance criteria. Terminology Standards define terms and explain symbols, abbreviations, and acronyms.

Classification Standards are systematic arrangements or divisions of materials, products, systems, or services into groups based on similar characteristics such as origin, composition, properties, or use. Guide Standard is a collection of information or a series of options that do not specify a particular course of action. They provide information about knowledge and approaches in specific subject areas.
