A structure of measurement standard (MS) base of every country reflects the structure of the International System of Units based on the base unit MSs. Taking into account that a metrological foundation is reproduction and conservation of the physical units therefore every country creates and develops their national MSs to provide its economic activities and to receive reliable and accurate results of measurements. In Belarus a foundation of the MS base is national and reference standards of base units of SI. There is a normative document in Belarus which determine choice, official recognition, use and conservation of MSs depending on physical unit reproduction based on theoretical definition of unit, metrological characteristics of MSs, etc. At the moment Belarus has eight national MSs, seven reference standards and over forty thousand working standards. Interrelationship between MSs and working standards is carried out by transference chain of physical unit dimension from national MSs to other measuring instruments in other words to standards of the verifying and calibrating structures and then directly to customers. This process of transference is regulated on the international level by international document ?5 "Principles for the establishment of hierarchy schemes for measuring instruments "(1982) but on the regional level by a state standard of USSR "GOST 8.061-80 " Verification schedules. Scope and layout." However, these documents do not take into account all peculiarities and new demands. Therefore, assurance system of measurement uniformity of Belarus does work out ideology and documents for hierarchy schemes regarding international and regional requests.
