BS EN ISO 6507-2:2018规定了试验机和设备的验证和校准方法 根据ISO 6507-1测定维氏硬度的测量系统。规定了试验机、压头和压头的直接验证和校准方法 对角线长度测量系统。规定了使用参考试块的间接验证方法 用于机器的全面检查。如果试验机也用于其他硬度试验方法，则应进行验证 每种方法都是独立的。本文件也适用于便携式硬度试验机，但不适用于硬度试验机 基于不同测量原理的试验机，例如超声波阻抗法。交叉引用:ISO 376ISO 6507-1ISO 6507-3购买时可用的所有现行修订版均包含在本文件的购买中。

BS EN 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.This document 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.Cross References:ISO 376ISO 6507-1ISO 6507-3All current amendments available at time of purchase are included with the purchase of this document.
