标准范围

本文件规定了根据ISO测定洛氏硬度的试验机的两种独立验证方法（直接和间接）？6508-1，以及用于验证洛氏硬度压头的方法。直接验证方法用于确定与机器功能相关的主要参数，如施加的力、深度测量和测试周期定时是否在规定的公差范围内。间接验证方法使用多个校准的参考硬度块来确定机器测量已知硬度材料的能力。本文件适用于固定式和便携式硬度试验机。需要注意的是，将碳化钨复合材料用于球压头被认为是洛氏压头球的标准类型。

This document specifies two separate methods of verification of testing machines (direct and indirect) for determining Rockwell hardness in accordance with ISO 6508-1, together with a method for verifying Rockwell hardness indenters.

The direct verification method is used to determine whether the main parameters associated with the machine function, such as applied force, depth measurement, and testing cycle timing, fall within specified tolerances. The indirect verification method uses a number of calibrated reference hardness blocks to determine how well the machine can measure a material of known hardness.

This document is applicable to stationary and portable hardness testing machines.

Attention is drawn to the fact that the use of tungsten carbide composite for ball indenters is considered to be the standard type of Rockwell indenter ball.
