Impact testing: ensure the reliability of your products
In the American ASTM standard, testing is mainly performed according to the Izod test method, which is described in ASTM D256. Within this standard all impact tests are performed using notched specimens. If only small specimens can be produced, the chip impact method to ASTM D4508 can be used. It is a counterpart to the Dynstat impact test.
