I have described the solution of a number of problems that arose during the development of verification of temperature standards of the 1st category. A refined procedure for determining inhomogeneity is proposed, additional requirements for external conditions during measurements are listed, and the permissible value of inhomogeneity is specified. It has been experimentally confirmed that the method established in the verification procedure for estimating the random component of the measurement error when verifying reference thermoelectric thermal converters of the 1st category underestimates the results obtained by 1.2–2.1 times.
The work can be useful for specialists involved in the verification of measuring instruments and temperature standards.
