Abstract
The urgency of the problem of determining the intervals between verification of measuring instruments has grown significantly over the past few years. This is mainly due to the emergence of new regulatory documents, as well as increased competition in the market for measuring instruments. This article discusses the main approaches to determining the intervals between verifications. The tasks currently facing in determining the intervals between verifications are analyzed. The normative documents regulating the procedure for assigning and changing the intervals between verifications are considered. The regulatory, technical and methodological problems in determining the intervals between verifications and calibrations are highlighted. The intervals between verifications for 12 pressure sensors were experimentally determined based on metrological failure tests. The comparison of the results of experimental and theoretical methods for determining the determination of the intervals between verifications is carried out. It is concluded that it is necessary to develop modern approaches in the theory of metrological reliability. To expand the possibilities for determining the metrological reliability of measuring instruments, scientific approaches to determining the intervals between verifications are formulated. The results obtained can be applied during testing to approve the type of measuring instruments.
