ISO 14253-1 establishes decision rules for verifying conformity or nonconformity of workpieces with specifications by formally incorporating measurement uncertainty. The 2017 standard mandates that conformity is only proven when the measured value falls within the tolerance zone reduced by the uncertainty, providing a standardized framework for global industrial dispute resolution.
