Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:

ISO 6892-1 – Tensile Testing Metallic Materials at Room Temperature

To request a quotation for any test email for a prompt reply

The ISO 6892 – 1 method covers the tension testing of metallic materials at room temperature and defines the mechanical properties that can be determined by this testing.

Tests can be performed in either stress control or strain control (including crosshead displacement). The strain control method may minimize the variation of the test rates during times when strain rate sensitive parameters are determined.

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.

Touchstone Engineers have performed both standard and customized tensile testing. In addition to mechanical testing capability, for tests such as ISO 6892 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.
