ASTM D 412 - 16 Standard Test Methods for Vulcanized Rubber and Thermoplastic Elastomers - Tension

Current edition approved Nov. 1, 2016. Published December 2016. Originally approved in 1935. Last previous edition approved in 2015 as D412 – 15a. — 14 p.
These test methods cover procedures used to evaluate the tensile (tension) properties of vulcanized thermoset rubbers and thermoplastic elastomers. These methods are not applicable to ebonite and similar hard, low elongation materials.
The methods appear as follows:
Test Method A - Dumbbell and Straight Section Specimens
Test Method B - Cut Ring Specimens
These two different methods do not produce identical results.
