洛氏硬度测量不确定度的评定

Evaluation of uncertainty in measurement of Rockwell hardness

本文在规定环境条件下,选用HRA,HRB和HRC标尺对硬度块(包括82.0HRA,65.9HRA,100.9HRB,87.3HRB,53.7HRB,59.8HRC,45.6HRC,28.1HRC,以下简称HRA高、HRA中,HRB低、HRB中、HRB高,HRC高、HRC中、HRC低)进行硬度试验,测得HRA,HRB和HRC值,进行不确定度的评定。

This paper used HRA under specified environmental conditions, HRB, and HRC scale of hardness blocks(including 82.0 HRA, 65.9 HRA, 100.9 HRB, 87.3 HRB, 53.7 HRB, 59.8 HRC, 45.6 HRC, 28.1 HRC, HRA, hereinafter referred to as HRA, HRB, HRB, HRB in low, high HRC, HRC and HRC were low) the measured hardness test, HRA, HRB and HRC value of uncertainty.
