ISO 6507-2:2018规定了根据ISO 6507-1测定维氏硬度的试验机和对角线测量系统的验证和校准方法。 规定了试验机、压头和对角线长度测量系统的直接验证和校准方法。为全面检查机器，规定了使用参考试块的间接验证方法。 如果试验机也用于其他硬度试验方法，则应对每种方法进行独立验证。 ISO 6507-2:2018也适用于便携式硬度试验机，但不适用于基于不同测量原理的硬度试验机，例如:。 g、 超声阻抗法。

ISO 6507-2:2018 specifies a method of verification and calibration of testing machines and diagonal measuring system for determining Vickers hardness in accordance with ISO 6507？1. A direct method of verification and calibration is specified for the testing machine, indenter and the diagonal length measuring system. An indirect verification method using reference blocks is specified for the overall checking of the machine. If a testing machine is also to be used for other methods of hardness testing, it shall be verified independently for each method. ISO 6507-2:2018 is also applicable to portable hardness testing machines but not applicable to hardness testing machines based on different measurement principles, e.g. ultrasonic impedance method.
