Abstract
Determination and assignment of reasonable intervals between certifications of standards is an important task to ensure the uniformity of measurements. The standards are intended for further transfer of the unit to standards and measuring instruments lower down the verification scheme, which means that exceeding the permissible values by metrological characteristics during operation is unacceptable, since it may lead to unreliability of the further transfer of the unit along the traceability chain. This risk can be reduced by finding the optimal interval between certifications, during which the metrological characteristics of the standard will not exceed the permissible values.
The article proposes one of the options for determining the interval between certifications based on the analysis of the measurement model of the standard and modeling the time dependence of the error limits of the estimates of input quantities, including taking into account factors that are not directly involved in the measurement process but influence this process.
