1. D ifferent test standards T he plastic charpy impact test equipment is meet the requirement of ISO179, GB/T1043, GB/T2612, JB/T8762 and GB4742. The izod impact test equipment is meet the requirement of ISO180, ASTMD256, GB/T1843, GB/T2611, JB/T8761 and etc.. 2. Different impact strength The plastic charpy impact tester measures the resistance of the material when it is impacted by the pendulum hammer . The charpy impact energy is defined as the energy absorbed by the specimen under the impact. It is a performance indicator that can be used in the quality control of production processes and can also be used to compare the toughness of different materials. The izod impact tes t equipment measures the impact resistance of the material when it is impacted by a pendulum hammer . Izod impact strength (notched), notched specimen izod impact strength is defined as the energy absorbed from the beginning ...
