Flow 05 — Shelf-life and calibration control
Prevent expired material or overdue instruments from being used until supported by current evidence and an independent decision.
Overview
Blocked stock remains on hand but is unavailable. Re-life, calibration or a valid controlled override changes eligibility—not the physical quantity.

Detailed steps
- 1
Create or receive a shelf-life batch or serialized instrument with its controlling dates.
- 2
Run the control sweep or attempt use after expiry/due date and confirm atomic blocking.
- 3
Upload and select the correct CLEAN laboratory or calibration certificate version.
- 4
Have a different authorised person approve or reject the request.
- 5
Verify only the matching decision or valid override changes eligibility.
Field-by-field practice data
Register a calibrated torque tool and retain one passing certificate without extending life silently. The page shows sample set A; the workbook includes independent A, B and C values.
Field names match the current application labels. Select existing approved records where shown, leave optional values blank unless they genuinely apply, and never copy fictitious TRAIN values into live work.
Record calibration evidence
Open the exact serialized tool and enter the certificate facts reviewed from the laboratory record.
| Exact field name | Requirement | Sample value A | How to use it |
|---|---|---|---|
| Serialized stock | Select existing | TRAIN-A-TORQUE-001 | Select the exact physical tool identity. |
| Asset code | Required | TRAIN-A-TOOL-001 | Use the governed asset alias. |
| Certificate reference | Required | TRAIN-A-CAL-CERT-001 | Reference the immutable controlled certificate. |
| Result | Required | PASS | Record the actual laboratory result. |
| Calibrated on | Required | 2026-09-01 | Use the certificate date. |
| Valid until | Required | 2027-09-01 | Must match approved frequency and certificate. |
| Calibration laboratory | Required | Training Metrology Laboratory | Use the exact supplier/lab identity. |
| Standard reference | Required | ISO/IEC 17025 · TRN-PROC-01 | Record the applicable procedure. |
Expected result: The calibration status and validity are attributable; a failed result follows the governed exception path.
End state
No expired or overdue identity can be consumed merely because quantity exists; evidence and independent authorization govern availability.
