标准摘要
[中文适用范围]： 本部分规定了金属材料焊接接头微硬度试验的范围、规范性引用文件、术语和定义、原理、试样的制备、试验程序、测试结果及测试报告。它适用于使用维氏硬度计在0.98N至49N（HV 0.1至HV5）范围内进行微硬度测试，但不适用于激光或电子束焊接等非常窄焊缝的硬度测试。 [外文原描述]： ISO 9015-2:2016 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). 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).
