Destructive tests on welds in metallic materials - Hardness testing - Part 2: Microhardness testing of welded joints (ISO 9015-2:2016); German version EN ISO 9015-2:2016
Zerstörende Prüfung von Schweißverbindungen an metallischen Werkstoffen - Härteprüfung - Teil 2: Mikrohärteprüfung an Schweißverbindungen (ISO 9015-2:2016); Deutsche Fassung EN ISO 9015-2:2016
Overview
This part of ISO 9015 specifies microhardness testing on transverse sections of welded joints of metallic materials with high hardness gradients. It covers Vickers hardness tests in accordance with ISO 6507-1, normally with test loads of 0,98 N to less than 49 N (HV 0,1 to less than HV 5). This part of ISO 9015 is not applicable to hardness testing of welds with loads of 49,03 N and above, which is covered by ISO 9015-1. This part of ISO 9015 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, such as those typically produced by laser and electron beam welding (see ISO 22826). The responsible standardization committee is Joint Working Committee NA 092-00-05 GA "Gemeinschaftsarbeitsausschuss NAS/NMP: Zerstörende Prüfung von Schweißverbindungen (DVS AG Q 4/Q 4.1)" ("Joint Working Committee NAS/NMP: Destructive testing of welds (DVS AG Q 4/Q 4.1)") at DIN Standards Committee Welding and allied processes (NAS).
