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

2020

7

ASTM Vol.08.01 (2022)

This test method covers the determination of the temperature at which plastics and elastomers (as defined by Terminology D883) 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 D2137. When testing plastic sheeting for impact brittleness, use Test Method D1790The values stated in SI units are to be regarded as the standard. 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.
