SNV - SN EN ISO 22826

Destructive tests on welds in metallic materials - Hardness testing of narrow joints welded by laser and electron beam (Vickers and Knoop hardness tests)

active, Most Current
Organization: SNV
Publication Date: 1 June 2021
Status: active
Page Count: 28
ICS Code (Welded joints and welds): 25.160.40
scope:

ISO 22826:2005 specifies the requirements for hardness testing of transverse sections of narrow laser and electron beam welded joints in metallic materials. It covers Vickers and Knoop hardness tests in accordance with ISO 6507-1 and ISO 4545, respectively, with test forces of 0,098 N to just under 98 N (HV 0,01 to just under HV 10) for the Vickers hardness test and test forces up to and including 9,8 N (just under HK 1) for the Knoop hardness test.It is applicable to welds made with or without filler wire. It may not be applicable to the testing of wider hybrid laser/arc welds.
