Read every finding before submission.
Warning
A warning allows continued preparation but requires attention. Examples include due-soon calibration, unverified accreditation, qualitative restrictions, late approval, or optional uncertainty gaps.
Prohibited
Normal submission is blocked for expired or uncalibrated standards, invalid source results, missing required certificates, inactive equipment, incompatible quantity, unit or range, blocking restrictions, cycles, or a required chain with no accepted terminal.
Quality and calibration managers may record a controlled exception where organisation policy permits. The reason is mandatory, the original prohibition remains visible, and the independent approver must acknowledge the exception.
An as-found failure prohibits standard use until the related out-of-tolerance case explicitly restores suitability, even if the as-left result passed.
Review older blocking restrictions
An older saved selection may contain a blocking restriction whose eligibility was calculated under the previous policy. Metra preserves that evidence and requires a fresh review before submission or approval. In a draft, review the selected standards and restrictions, enter a save reason, and save the reference-standard selection again. Resolve any prohibition or record a permitted controlled exception with its required evidence. If the calibration has already been submitted, return it for correction before reviewing and saving. Previously approved records retain their frozen history.
Restoring suitability after an out-of-tolerance result
An as-found failure remains prohibited until the out-of-tolerance investigation reaches a disposition that explicitly restores the standard to suitable service. A passing as-left reading alone does not restore eligibility. The restored state applies prospectively and does not rewrite the original failure, exception, or frozen usage revision.
