State Primary Standard of Length for Deviations from Straightness and Flatness
Reproduction and maintenance of length unit in the field of measurement of deflections from linearity and planarity.
Transferring of the size of length unit in the field of measurement of deflections from linearity and planarity to the working standards by means of the method of direct measurements in accordance with DSTU 3386-96 “Metrology. National verification scheme for measuring instruments of deflections from linearity and planarity”.
