ASTM E8/E8M
Revision: 2022
Material testing
Standard test methods for tension testing of metallic materials
Establishes tension testing methods for metallic materials to determine yield, tensile strength, elongation, and reduction of area, including procedures for sheet, wire, and machined specimens in inch-pound and SI contexts.
Test method
Specimens are pulled to fracture while measuring force and displacement; properties are computed using defined gauge lengths, extensometry rules, and reporting formats common in ASTM material specifications.
Specimen requirements
Specimen dimensions and alignment shall meet E8/E8M tolerances; grip selection must minimize bending. For thin products, width and thickness measurements influence stress calculations and must be taken at defined locations.
ASTM E8/E8M aligns conceptually with ISO 6892-1 but uses customary ASTM terminology and reporting conventions.
