Project X10-612 ASTM D638-14 section 8.2 specifies that the lowest speed of testing shall produce a rupture within 0.5 to 5-min testing time. Extremely brittle polymers rupture below this minimum threshold and would be excluded from testing under this standard. As no other standard exists for the tensile testing of non-composite polymers, this revision aims to address this deficiency.
