1.1 This test method covers the determination of the temperature at which plastics and elastomers (as defined by Terminology ) 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 Method . When testing plastic sheeting for impact brittleness, use Test Method .
1.2 The values stated in SI units are to be regarded as the standard.
1.3 Due to the potential safety and environmental hazards associated with mercury-filled thermometers, the use of alternative temperature measuring devices (such as thermocouples and RTDs) is encouraged.
1.4 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 address the same subject matter, but differ in technical content.
