ASTM E8

Tensile Test

The test methods described in the ASTM E8 specification cover the tension testing of metallic materials in any form at room temperature, and more specifically, the methods used to determine yield strength, yield point, tensile strength, elongation, and reduction of area.

Tension tests determine the strength and ductility of materials under uniaxial tensile stresses. This information may be helpful in comparisons of materials, in the development of new alloys, for quality control, to support structural design, and acceptance testing for commercial shipments.

Proper test specimen alignment, grip and face selection are critical factors in obtaining valid test results. Test specimens must be aligned correctly at the beginning of a test to avoid bending moments or side loading. The specimen must also remain in this perfect alignment throughout the duration of the test. If the specimen slips in the grips, or becomes deformed in the grip area, the test would be invalidated. Here at WMT&R, with the help of our Mechanical Engineering Department, and our in-house Full Service Machine Shop, we custom design and manufacture specialized grips and fixtures.
