ASTM Standards

← Back to all standards

ASTM International is one of the world’s largest voluntary standards-development organizations. Its consensus documents define how materials are tested, specified, and reported, and are used worldwide for quality control, product development, and procurement.

Why ASTM standards matter in testing

An ASTM method fixes the variables that change a result (specimen geometry, conditioning, apparatus, loading rate, calculation, and reporting) so measurements stay comparable across suppliers, production lots, and laboratories.

What ASTM standards cover

ASTM standards are grouped into lettered series by material or subject:

Series Scope
A Ferrous metals (steel and iron products)
B Nonferrous metals (aluminum, copper, magnesium)
C Ceramics, concrete, and masonry
D Miscellaneous materials such as plastics, rubber, paper, and textiles
E Miscellaneous subjects such as test methods, statistics, and machine verification
F End-use products such as fasteners, medical, and consumer goods

Common test types

Tension, compression, flexure (bend), impact, and shear or peel and tear, plus practices for verifying machine force and extensometers. Most are performed on a universal testing machine with matched grips, fixtures, and extensometry.

How to read a ASTM designation

A designation combines a series letter, a sequential number, an optional M for the SI (metric) companion, and a hyphenated year of adoption or last revision:

Part Example Meaning
Letter E Series (here, general test methods)
Number 8 Sequential standard number
M E8M Metric (SI) companion version
Year -21 Year of adoption or last revision
