标准摘要
[中文适用范围]： 本文件规定了根据 ISO 6507-1 确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。 规定了使用参考块的间接验证方法来对机器进行整体检查。 如果试验机还用于其他硬度测试方法，则应对每种方法进行独立验证。 本文件也适用于便携式硬度计，但不适用于基于不同测量原理的硬度计，例如超声阻抗法。 [外文原描述]： 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.
