There are ISO product, method, and instrument standards for impact tests with pendulum impact testers.
Product and method standards describe how specimens are taken from a variety of materials and tested. Alternatively they describe a test method for a product or material group.
Instrument standards describe how test instruments are designed. They specify the technical data and their tolerances and define how testing instruments should be verified.
While our customers mainly rely on product standards, as a manufacturer of instruments ZwickRoell is bound by both product standards (for the test sequence) and instrument standards (for the technical design of the test instrument). Both groups of standards are therefore listed below.
As a rule, ASTM standards do not differentiate between product, method, or instrument standards.
