Overdue: the due date worked out is earlier than the as-at date
Every standard here asks for calibration or verification of measuring equipment at set intervals, and for its status to be known. A due date earlier than the as-at date is the first thing a certification body auditor samples. A due date equal to the as-at date reads as due today, not overdue.
When the finder raises it
Fires when the due date worked out (last calibration plus interval) is earlier than the as-at date, for an instrument in service. A due date equal to the as-at date is due today, not overdue. Out-of-service, lost, quarantined, retired, reference-only and calibration-not-required instruments raise no date finding. Where the register has a control type column, the wording names it: a verification due, not a calibration due.
A question for the quality manager
Is it out of use until it is done, and who books it?

ISO 9001 7.1.5Monitoring and measuring resourcesWhere monitoring or measurement is used to check that products and services conform, the organization identifies and provides the resources needed for results to be valid and reliable. It makes sure those resources suit the kind of monitoring and measurement done and are maintained so they stay fit for purpose, and it retains documented information as evidence that they are. Where traceability of measurement is required, or the organization judges it essential to confidence in the results, measuring equipment is: calibrated or verified, or both, at set intervals or before use, against standards traceable to international or national ones (and where none exist, the basis used is recorded); identified so its status is known; and protected from adjustment, damage or deterioration that would make its calibration status or later results invalid. If equipment proves unfit for its purpose, the organization judges whether earlier results remain valid and acts as needed.
