ASTM International, formerly known as the American Society for Testing and Materials, is one of the world’s leading standards development organizations. It develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services used across industries globally.

ASTM standards ensure quality, safety, reliability, and performance in manufacturing and industrial processes. Today, more than 12,000 ASTM standards are used worldwide by manufacturers, laboratories, governments, engineers, and quality professionals.

What is ASTM?

ASTM is an internationally recognized organization that creates technical standards through a consensus-based process involving industry experts, scientists, engineers, regulators, and consumers.

 These standards define:
 Material composition
 Mechanical properties
 Chemical properties
 Testing procedures
 Performance criteria
 Safety requirements
 Quality benchmarks
 ASTM standards are voluntary but are often incorporated into regulations, contracts, and certifications.
