scope:

This Defence Standard gives guidance on methods for evaluating the factors contributing to uncertainty in electrical measurements and for combining these into a single (±) limit figure.

Consideration is given to the economics of measurement uncertainty in the design, manufacture, calibration and testing of the product and to assessing the extent of the risk. It is recommended that the methods described herein should be adopted as standard procedure.

NOTE: This Defence Standard is concerned with the uncertainty of a single valued result of the measurement of a single parameter. It is not applicable, for example to the departure of a measured characteristic from a prescribed curve, neither is it concerned with sampling schemes for batch testing.
