Non UKAS Calibration – Length and Capacity

Length measures are compared against our Local Standard length measures, which have been examined and certified by the National Weights and Measures Laboratory.

Capacity measures are tested gravimetrically using weighing machines, in accordance with National Weights and Measures Laboratory requirements. We frequently test metal measures used for testing petrol pumps, graduated glass pipettes, and graduated glass flasks.
