Standard measures for transfer of the size of unit of length from the primary stage to end measures of smaller accuracy and for checking and calibration of measuring devices. They are made of steel or hard alloy.Numbers of sets, number of measures in sets, nominal values of lengths of measures and their gradation, accuracy classes are specified in the table. Plane-parallel end measures of length are issued by special sets according to GOST No. 9038 and are used in need of adjustment or regulation of devices for measurements, and also at direct measurement of the controlled sizes.
In addition, a set of plane-parallel end measures is used as a single standard for the size of the basic units of length in accordance with the required accuracy, which determines the error tolerance field. For the manufacture of such measuring devices using steel or hard alloy, all the characteristics of each set are fixed in the appropriate tables, which are subject to strict observance.
Often with the help of end measures of length there is a setting of machines and devices, particularly accurate marking devices, devices and so on. I always strive to resolve any problems and make our customers happy. Arrive time is contingent on the carrier.
