ASTM D412-2015 Tension Test for Rubber and Elastomers
ASTM D412-2015 describes a method for determining the tensile stress-strain properties of vulcanized and thermoplastic rubbers. The standard has two methods, A and B, depending on the specimen geometry being tested. Method A refers to the use of dumbbell shaped specimens, while method B refers to ring shaped specimens. The properties which can be determined are tensile strength, elongation at break, stress at a given elongation, and yield point. The measurement of stress and strain at yield applies only to some thermoplastic rubbers and certain other compounds.
The challenges of testing to this standard are:
It is important to review ASTM D412-15 in order to fully understand the test setup, procedure, and results requirements.
