"Standard Test Method for Tension Testing of Metallic Materials"
The ASTM E8 method covers the tension testing of metallic materials in any form at room temperature, specifically, the methods of determination of 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.

Grip and face selection are very important to obtain accurate results. Specimen alignment is key to avoid side loading or bending moments. Touchstone’s extensive experience in composites testing, which are more sensitive to alignment, ensures control of this critical parameter in testing metallic materials. This is particularly important for R&D projects, where a reference standard or specification may not be available, and improper alignment could yield results that are incorrect but unknown.

In addition to mechanical testing capability, for tests such as ASTM E8 and many other ASTM methods, Touchstone can conduct complete metallurgical and/or failure analysis using its laboratories for light microscopy, scanning electron microscopy (SEM), and metallography.
