An analysis of the structure and content of verification technique MP 002.D4-14, extends to coating thickness gauges TM-2, TM-3, TM-4, and TM-4T, technique MP 159-261-2016 for verification of SaluTrjn coating thickness gauges, and a technique for verification of coating thickness gauges regulated by GOST 8.502–84 is performed. It is shown that the first two techniques do not take into account the random component of the error, while the third technique does take into account the random component but not correctly. These factors all lead to a high probability of a wrong identification of a model of a thickness gauge that is, in reality, defective to be, instead, a working model or, on the other hand working devices may be incorrectly identified as being defective. To increase the reliability of the results of a verification of coating thickness gauges, recommendations that suggest incorporating them into the content of a verification technique regulated by GOST 8.502–84 are proposed.
