3. Definitions
- Calibration: The process of comparing a measurement instrument to a known standard to ensure accuracy.
- Verification: Confirming that a measurement instrument is functioning correctly.
- Adjustment: Modifying a measurement instrument to bring it into compliance with standards.
- As Found: The condition of the instrument prior to any adjustments.
- As Left: The condition of the instrument after adjustments have been made.
- OOT (Out of Tolerance): A condition where the measurement exceeds specified limits.
- Drift: The gradual change in a measurement instrument’s output over time.
- Traceability: The ability to trace the history, application, or location of an item through documented recorded identification.
- Measurement Uncertainty: A parameter that characterizes the range of values within which the true value is asserted to lie.
- Intermediate Check: A verification performed between calibrations to ensure ongoing accuracy.
4. References
- Company Metrology SOP [TBD]

8. Calibration Strategy
Calibration will follow the As Found then As Left logic. The minimum number of test points will be 5, including endpoints and midpoints within the range of 0% to 100%. Each point will have 3 replicate readings as a best practice.
9. Step-by-Step Procedure
- Preparation: Gather all necessary tools and documentation.
- Stabilization: Allow the HEPA Filter Leak Tester to stabilize as per manufacturer instructions.
- As Found checks and data capture: Record initial measurements at defined test points.
- Adjustment rules: If OOT is found, follow adjustment protocols; if not allowed, escalate to QA.
- As Left verification: Confirm that the instrument is within tolerance after adjustments.
- Labeling + documentation completion: Complete all required documentation and label the equipment accordingly.
Record raw observations contemporaneously to ensure data integrity (ALCOA+).
10. Acceptance Criteria & Calculations
Acceptance criteria are as per ISO14644. The error calculation formula will be: Error = (Observed Value – True Value) / True Value * 100%. Pass/fail logic will be based on whether the error falls within acceptable limits. Rounding rule: [TBD].
11. Handling OOT / Failures
- Immediate containment: Tag equipment and stop use.
- Notification & deviation initiation: Notify relevant personnel of the OOT condition.
- Impact assessment trigger: Define impact window and review of affected results/batches.
- Recalibration after repair/adjustment: Ensure recalibration is performed post-adjustment.
- QA disposition placeholders: [TBD].
12. Records & Retention
- Logbook entries: Document all calibration activities.
- Calibration report/certificate filing: Maintain records in accordance with company policy.
- e-Records if applicable: [TBD].
- Label content requirements: Include calibrated date, due date, technician name, and status.
