Standard weight and mass calibration
Standard weights are references for weighing checks. Unlike scale calibration, this work determines the mass value and uncertainty of each weight. Nominal values, classes, quantities and intended use are needed to plan the work.

Frequently asked questions
How is weight calibration different from scale calibration?
Weight calibration determines the mass value and uncertainty of a reference weight; scale calibration assesses the indicated values of a weighing instrument.
What information is needed?
Provide each nominal mass, accuracy class, quantity and identifier, plus previous certificates and intended acceptance criteria where available.
