1 This Technical Report is intended to provide possibilities for the simplification and harmonization of the specifications for mechanical testing of open die and closed die forgings in ISO Standards and other technical delivery conditions for forgings of steel.
For this purpose this Technical Report
a) offers various options for
— the frequency of testing and
— sampling conditions;
b) introduces a designation system for the options, mentioned under (a);
c) specifies the test methods for
— room temperature tensile tests
— elevated temperature tensile tests
— impact tests and
— uniformity checks by hardness tests.
2 Unless otherwise specified in this Technical Report the general conditions given in ISO 377 for the marking and preparation of samples and test pieces apply.
3 Where the conditions specified in this Technical Report differ from the conditions specified in the product standard or order, then the conditions of the product standard or order apply.
