Description: The question of providing of unity of measurings is considered by the increase of metrology noninteraction of the in-plant systems of measurings. Expedience of increase of metrology noninteraction is rotined by creation of «virtual» standard. The possible variants of realization of «virtual» еталона are analysed, which will provide high metrology stability of measurings at insignificant additional expenses. It is indicated on the necessity of creation of universal technical and programmatic backer-ups mutual collations for the in-plant systems of measurings for the increase of authenticity of measurings in the conditions of metrology noninteraction.
Keywords: metrology noninteraction, in-plant systems of measurings, facilities of measuring technique, metrology accordance, collation, calibration
