WebASTM and ISO have a number of tensile testing standards that are related to thermoplastic and thermosetting polymers. The two most common testing standards for plastic tensile testing are ASTM D638 and ISO 527. ASTM D638 and ISO 527 both use a dumbbell (aka dog-bone) specimen that is pulled to failure with a tensile testing machine. WebThe test beam is under compressive stress at the concave surface and tensile stress at the convex surface. ... The analogous test to measure flexural strength in the ISO system is … WebAll measure-ments were made at ambient conditions. The tensile behavior of the consumer products were compared qualitatively and quantitatively. Three mechanical phenomena were observed in the materials: linear elastic behavior, a strengthening or increase in modulus, and yielding or rapid elongation with minimal changes in stress. cjujitsu.com
