Abstract

It is shown that, unlike other means of measuring linear dimensions, coating thickness gauges do not have a regulatory framework governing their accuracy (error). It is noted that a number of external factors influence the reliability of the results of coating thickness measurements. Using the example of coating thickness gauges, the difference in the measurement results for two-point and zero calibration is shown.

Highlights

One of the main indicators of coating thickness gauge quality is their accuracy and reliability
The lack of a proper regulatory framework for coating thickness gauges leads to vagueness of these quality indicators
The accuracy of the measuring instrument is estimated by the accuracy class, which regulates the measurement error of this device

Summary

Introduction

One of the main indicators of coating thickness gauge quality is their accuracy and reliability. As for the second indicator of the quality of coating thickness gauges - the accuracy of the measurement results.
