适用范围：This International Standard specifies the requirements for hardness testing of transverse sections of narrowlaser and electron beam welded joints in metallic materials. It covers Vickers and Knoop hardness tests inaccordance 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 (justunder HK 1) for the Knoop hardness test.This International Standard is applicable to welds made with or without filler wire. It may not be applicable tothe testing of wider hybrid laser/arc welds.International Standards for hardness testing of welds without a narrow profile are ISO 9015-1 and ISO 9015-2.
