洛氏硬度测量不确定度评定

Uncertainty Assessment for Rockwell Hardness Measurement

针对多功能硬度计特点,结合洛氏硬度测量不确定度评定实例,介绍了其比较准确的评定方法和注意事项。指出不宜将检定证书上的信息用于不确定度评定,应以试验前校准信息作为不确定度评定依据。

The accurate assessment and points for attention for Rockwell hardness measurement are introduced in the paper based on the character of multi-functional sclerometer and the assessment cases of uncertainty measurements of Rockwell hardness. It is pointed out that the calibrated data before test are used to the uncertainty assessment rather than the data listed in the certificate.
