5. Checking a scale
The scale verification described in this article consists in comparing the error with the selected tolerance, without taking the uncertainty into account. The uncertainty can be determined by following the instructions given in the article
5.1 Choice of standards
The choice of standards must include the tolerance to be justified, in line with the maximum permissible errors set for scale use:
when the nominal mass is used, the ratio between the maximum tolerated error on the mass used and the maximum tolerated error on the scale to be verified is less than...
