MarGage Rectangular Gage Blocks (Steel and Ceramic) according to DIN EN ISO 3650 - 9205 MarGage. Standards, Gages and Gage Blocks

Rectangular Gages Blocks Application

• As comparison reference and utilization standards in the field of length measurement• For checking gages and measuring instruments• For setting devices of all types designed for length measurement and in particular their displays• Can be used individually or in combinations by wringing several blocks together (see illustration)

Accuracy

The manufacturing process is based on DIN EN ISO 3650, Mahr gage blocks are produced with the utmost care.

Marking

Gage blocks of all grades are clearly and individually marked with an identification number.

Material

Mahr gage blocks are made either of stainless steel or of the ceramic compound zirconium oxide ZrO2 (Circonimar).

Calibration Certificate

Gage blocks in sets are supplied with a Mahr calibration certificate stating deviations from the nominal size, this confirms the trace- ability to National Standards. For single gage blocks Mahr calibration certificates are available on request. A calibration certificate from the Mahr DKD Calibration Laboratory is recommended for gage blocks of calibration grade K in the range between 0,5 and 100 mm As a part of the German Calibration Service, the Mahr Calibration Laboratory calibrates steel and ceramic gage blocks of all brands in the range between 0.5 and 100 mm and issues calibration certificates. The gage block sets are marked with the official DKD calibration label. Calibration is based on the contract concluded between the Physikalisch-Technischen Bundesanstalt in Braunschweig and the company Mahr. mm mmfrom 0.5 - 10 30 x 9over 10 - 1000 35 x 9 Dimensions Nominal dimension Cross section
