Destructive tests on welds in metallic materials — Hardness testing — Part 2: Microhardness testing of welded joints
NOTE Testing ensures that the highest and/or the lowest level of hardness of both parent materials (in the case of dissimilar materials both parent materials) and weld metal is determined.
ISO 9015-2:2016 is not applicable to hardness testing of welds with loads of 49,03 N and above, which is covered by ISO 9015‑1.
ISO 9015-2:2016 is not applicable to Vickers hardness testing of resistance spot, projection and seam welds, which is covered by ISO 14271.
This part of ISO 9015 is not applicable to hardness testing of very narrow welds, e.g. those typically produced by laser and electron beam welding (see ISO 22826).
