标准范围

ISO 22826:2005规定了金属材料窄激光和电子束焊接接头横截面硬度试验的要求。它包括分别符合ISO 6507-1和ISO 4545的维氏和努氏硬度试验，维氏硬度试验的试验力为0098 N至略低于98 N（HV 0,01至略低于HV 10），努氏硬度试验的试验力为9,8 N（略低于HK 1）。适用于使用或不使用填充焊丝的焊缝。它可能不适用于更宽的混合激光/电弧焊缝的测试。

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.
