The Model 3800 extensometer is for rubber and elastomer tensile testing. Use it to measure tensile modulus, elongation at break, yield strain, and stress-strain curves of high-elongation materials.
ASTM D412 (D 412) covers the tensile properties of thermoset rubbers and thermoplastic elastomers. The specification describes two test methods, A and B. Method A is common and can be performed on a ...
