Application

M1 test weights are commonly used for testing and adjusting commercial balances, platform balances, industrial balances and checkweighers. They can also be used for the calibration and verification of weights of classes M2 and M3 according to OIML R111. M2 and M3 nach OIML R111 eingesetzt werden.

Depending on the accuracy requirements, precision weights of classes M1, M2 and M3 can also be used as load bodies for tensile, compression or torsion measurements.

  • Testing and adjustment of commercial balances of accuracy class III
  • Quality assurance of balances with medium resolution
  • Check weighing in industry, trade and production
  • Calibration of weights of classes M2 and M3
  • Use as test or measuring equipment within test equipment management
  • Use as load bodies for tensile, compression or torsion measurements

Marking of M1 Weights

According to OIML R111-1:2004, weights of class M1 from 1 g upwards are marked with their nominal value, but without unit information. To identify class M1, the class may additionally be applied.

For differentiation, weights of the same nominal value that occur more than once in weight sets can be marked with dots or stars.

In addition, customer-specific user markings, such as characters, letters or numbers, can be applied. This allows the weights to be clearly identified as test or measuring equipment and better integrated into internal test equipment management.

These user markings can be specified individually when ordering.
