Standard Test Method for Brittleness Temperature of Plastics and Elastomers by Impact

Scope

1.1 This test method covers the determination of the temperature at which plastics and elastomers exhibit brittle failure under specified impact conditions. Two routine inspection and acceptance procedures are also provided.

Note 1—When testing rubbers for impact brittleness use Test Methods D2137.

1.2 The values stated in SI units are to be regarded as the standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Note 2—This test method and ISO 974-1980 (E) are technically equivalent when using the Type B fixture and the Type III specimen, however, the minimum number of specimens that are required to be tested may be significantly different when using this test method. The ISO method requires that a minimum of 100 specimens be tested.
