This paper presents a new method that can be applied in the field of metrology to determine and change the intercalibration periodicity during the operation of measuring instruments (certified standard chemical samples) used in the field of state metrological control and supervision. In modern metrology, the key issue is the determination and correction of intercalibration periodicity during the use of measuring instruments. The present paper presents a new method that can be applied in the sphere of state metrological control and supervision to improve the accuracy and reliability of measurements. The proposed method is intended only for exemplary measuring instruments and measurement standards and is not allowed to be applied to working equipment (technical devices for metrology experiments) used in production processes or in accredited testing laboratories. The research that was conducted shows that there is no systematized approach to the collection of reliable information on the instability of measuring devices, which hinders the reasonable determination of the inter-calibration periodicity of measuring instruments (based on the statistical data given). The establishment of initial information requires a large amount of time and access to limited reliable sources of reference values of physical quantities. This is connected with the necessity to use the protocols of research stability tests, which determine confidence limits of the standard instability indicators for a given period of time, as well as protocols of reliability tests, which establish confidence limits of metrological reliability indicators of the standard.
