ASTM D412 – Standard Test Methods for Vulcanized Rubber and Thermoplastic Elastomers-Tension
1.1 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|
Note 1: These two different methods do not produce identical results.
1.2 The values stated in either SI or non-SI units shall be regarded separately as normative for this standard. The values in each system may not be exact equivalents; therefore each system must be used independently, without combining values.
