scope:

This standard sets out guidelines: a) for drafting requirements that may be formulated as limiting values for a quantifiable characteristic; b) for checking conformity to such requirements when the test or measurement result is subject to uncertainty. This part of ISO 10576 is applicable whenever the uncertainty may be quantified according to the principles laid down in GUM. The term uncertainty is thus a descriptor for all elements of variation in the measurement result, including uncertainty due to sampling. It is outside the scope of this part of ISO 10576 to give rules for how to act when an inconclusive result of a conformity test has been obtained.
