• Overall guidance on how to select appropriate rules.

What is the true statements about 'Guard Bands'?

• A safety factor built into the measurement decision process by reducing the acceptance limit below that of the specification/tolerance limit.

• To reduce the probability of making an incorrect conformance decision.

•

Which one is the FALSE suggestion on how to use the flow chart?

• If your application already has measurement decision rules governed by a published standard guidance document Generally, in these cases, standard test methods are prescribed and often compliance limits already have a guard band built in to the limit, so any further guard banding to limit risk is not necessary.

• If the measurement result is governed by legal or regulatory standards or rules, then use the decision rule as prescribed in the appropriate standard.

• Some calibration or testing applications do not require a statement of conformance to a metrological specification. In these cases, you should (shall for a calibration) report the measured result and the GUM measurement uncertainty.

• If you reach decision box 4, it generally means that no specific published decision rule already governs your application. Laboratories may select from standard decision rules shown or choose to self-document their own rule.

• If you reach decision box 4, it generally means that no specific published decision rule already governs your application. Laboratories and customers may select from standard decision rules shown or choose to self-document their own rule.
