ASTM Standards

What is ASTM Standards?

ASTM Standards, Consensus technical specifications developed by ASTM International that govern construction materials and testing.

Description

ASTM Standards are voluntary consensus documents published by ASTM International that specify material properties, testing methods, and performance criteria used across construction. Examples include ASTM C150 for Portland cement, ASTM E119 for fire resistance, and ASTM F1667 for nails. Architects cite ASTM numbers in specifications to ensure uniform quality and compliance with codes. Revisions occur regularly through committee balloting, so submittals must reference the current edition date.
