ISO 6507-2:2018规定了用于根据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。
为测试机,压头和对角线长度测量系统指定了一种直接的校验和校准方法。为机器的整体检查指定了使用参考块的间接验证方法。
如果测试机器也用于其他硬度测试方法,则应针对每种方法独立验证。
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。超声波阻抗法。
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.
