Metallic materials Conversion of hardness values
|Publication Date:||1 November 2003|
|ICS Code (Mechanical testing of metals):||77.040.10|
This International Standard specifies the principles of the conversion of hardness values and gives general information on the use of conversion tables.
The conversion tables in Аnnexes A to F apply to
- unalloyed and low-alloy steels and cast iron;
- steels for quenching and tempering;
- cold working steels;
- high speed steels;
- non-ferrous metals and alloys.
NOTE The conversion tables in Annexes B to E are based on empirical results which were evaluated by means of regression analysis. Such analysis was not possible in the case of the values given in Annex A because a sufficient number of results was not available.
