Release Time:2022-01-13 Impact strength is used to evaluate the impact resistance of materials or judge the degree of brittleness and toughness of materials, so impact strength is also called impact toughness. Impact strength is the ratio of the energy absorbed by the sample during the impact damage process to the original cross-sectional area.
Project Introduction:
Impact strength is used to evaluate the impact resistance of materials or judge the degree of brittleness and toughness of materials, so impact strength is also called impact toughness. Impact strength is the ratio of the energy absorbed by the sample during the impact damage process to the original cross-sectional area.
There are many methods to test the impact strength of engineering plastics, mainly including pendulum impact test and falling weight impact test. The pendulum impact test is divided into Charpy type and Izod type.
Classification of measurement methods:
Method standard:
Charpy impact test
GB/T 1043.1-2008 (ISO 179:2010)
The Part 1 of the measurement of plastic Charpy impact performance: Non-instrumented impact test
ASTM D6110-2018 Charpy impact strength test
Izod impact test
GB/T 1843-2008 (ISO 180-2000/Amd 2-2013)
The measurement of plastic Izod impact strength
ASTM D256-2010 (2018) The standard test method for plastic Izod pendulum impact resistance
