scope:

Specifies micro hardness tests on transverse sections of welded joints of metallic materials with high hardness gradients. It covers Vickers hardness tests in accordance with ISO 6507-1 and/or ISO 6507-2, normally with test loads of 0,98 N to 49 N (HV 0,1 to HV 5). Testing should be carried out to ensure that the highest and/or the lowest level of hardness of both parent metal and weld metal is determined. The type and extent of testing shall be as specified by the relevant application standard by agreement between the contracting parties. This standard does not cover the hardness test as described in prEN 1043-1.
