DIN 861
Table of tolerances for gauge blocks according to DIN 861, corresponds with ISO 3650 and SS 3348.
DIN 861 specifies the most important dimensional and quality characteristics of gauge blocks with a rectangular cross-section and a nominal length ln ranging from 0,5 to 1000 mm. The permissible deviations and tolerances are stated for four grades of accuracy, i.e. 00, 0, 1 and 2 and the calibration Grade K.

DIN 875
Standard DIN 875 refers to the squareness of machined surfaces; all those parts which require accuracy on one or more corners at 90° use this standard.
The DIN standard relating to squareness or verticality between two surfaces regulates the maximum deviation, according to the envisaged degree of accuracy, of adjacent surfaces with respect to a fixed value of 90°.
This deviation is measured using the following formulas:
•DIN 875/II° = 0.02 + L/10.000 mm
•DIN 875/I° = 0.01 + L/20.000 mm
