NF EN 1043-1

<p>This part of ISO 9015 specifies hardness tests on transverse sections of arc welded joints of metallic materials. It</p> <p>covers Vickers hardness tests in accordance with ISO 6507-1, normally with test loads of 49,03 N or 98,07 N (HV 5</p> <p>or HV 10).</p> <p>However, the principles may be applied to Brinell hardness testing (with appropriate testing loads of HB 2,5/15,625</p> <p>or HB 1/2,5) in accordance with ISO 6506-1 and micro hardness testing in accordance with ISO 6507-1 and</p> <p>ISO 9015-2.</p> <p>NOTE Testing should be carried out to ensure that the highest and the lowest level of hardness of both parent metal and</p> <p>weld metal is determined.</p> <p>This part of ISO 9015 does not apply to test welds in austenitic stainless steels.</p>
