Precision weights of accuracy class M1

Class M1: Weights for the verification or calibration of weights of class M2, as well as weights for use with scales of accuracy class III.

Class M2: Weights for the verification or calibration of weights of class M3 and weights for use with scales of accuracy class III in general commercial transactions.

Test weights, weights for scales, calibrated weights, calibration weights, check weights, calibration certificates. M1 class test weights are suitable as test and calibration instruments for commercial scales and for quality assurance in accordance with DIN EN ISO 9001ff for scales with a scale interval < 30,000. These weights are also used as calibration weights for the calibration of class III scales.
