How many types of ASTM are there?


ASTM International, formerly known as the American Society for Testing and Materials (ASTM), is a globally renowned organization that develops and publishes voluntary technical standards for a wide range of products, materials, systems, and services. These standards ensure product quality, safety, and performance consistency across industries.

ASTM Standards Classification

ASTM standards cover various disciplines such as construction, metals, textiles, plastics, petroleum, and more. They are classified into different types based on their purpose and content. Let's dive into the main types of ASTM standards:

Type 1: Specification Standards

Specification standards are the most common type of ASTM standards. They define specific requirements for materials, products, or systems. These standards establish criteria such as chemical composition, physical properties, performance characteristics, and manufacturing processes. For example, ASTM A36 specifies the requirements for structural steel used in buildings and bridges. Specification standards enable manufacturers, suppliers, and consumers to ensure consistent quality and compatibility.

Type 2: Test Method Standards

Test method standards describe procedures and techniques to measure and evaluate certain properties or characteristics of materials or products. They provide standardized testing methods, instrumentation, and statistical analysis guidelines. Test method standards facilitate accurate and comparable test results across different laboratories and organizations. ASTM D4236 outlines the testing methods for art materials such as paints and markers, ensuring their safety for use by artists and children.

Type 3: Practice Standards

Practice standards offer guidance on the general procedures and practices associated with a particular industry or field. Unlike specification or test method standards, they do not establish specific requirements. Practice standards assist industry professionals in making informed decisions and conducting activities effectively. For instance, ASTM E2018 provides guidelines for property condition assessments of real estate properties. These standards promote consistency and best practices to enhance efficiency and professionalism.


ASTM standards play a vital role in ensuring product quality, safety, and performance across industries. From specification standards that establish criteria for materials and products to test method and practice standards that provide standardized procedures and guidance, ASTM fosters innovation, reliability, and trustworthiness. By following these internationally recognized standards, manufacturers, suppliers, and consumers can have confidence in the products they produce, use, and rely on.
