Destructive tests on welds in metallic materials. Hardness testing - Hardness test on arc welded joints not-eligible equipment manufacturers and those involved1 Scope This part of ISO 9015 specifies hardness tests on transverse sections of arc welded joints of metallic materials. It covers Vickers hardness tests in accordance with ISO 65071, normally with test loads of 49,03 N or 98,07N (HV5 or HV 10). However, the principles may be applied to Brinell hardness testing (with appropriate testing loads of HB 2,5 15,625 or HB 1 2,5) in accordance with ISO 65061 and micro hardness testing in accordance with ISO
