Gauge Blocks Tolerances Specifications Table DIN 861

Tolerances, Engineering Design & Limits & Fits

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.

Nominal Legnth mm	Precision 00		Precision 0		Precision 1		Precision 2
