洛氏硬度试验中加荷速度和总负荷保持时间的选择

Choices of Loading Speed and Keeping Time of Gross Load for Rockwell Hardness Tests

本文对大批量检测较高硬度材料的洛氏硬度试验（Ｃ标尺）中主负荷施加速度和总负荷保持时间的选择作了理论分析和实验证明，目的是在提高工效的同时，进一步保证试验精度。

The choices of loading speed and keeping time of the gross load for the Rockwell hardness tests are theoretically analyzed and certified experimentally in the paper.The purposes are to improve the working efficiency and the testing accuracy.
