ASTM E 21 Standard Test Methods for Elevated Temperature Tension Tests of Metallic Materials
This specification covers test methods, procedure and equipment for the determination of tensile strength, yield strength, elongation, and reduction of area of metallic materials at elevated temperatures.
The principal usefulness of the elevated-temperature tensile test is to assure that the tested material is similar to reference material when other measures such as chemical composition and microstructure also show the two materials are similar. It is also useful for estimating the static load-carrying capacity of metals under short-time, tensile loading. Using established and conventional relationships it can be used to give some indication of probable behavior under other simple states of stress, such as compression, shear, etc. The ductility values give a comparative measure of the capacity of different materials to deform locally without cracking and therefore to accommodate a local stress concentration or overstress.
WMT&R performs the elevated temperature test up to 2200°F.
