3. Definitions
- Calibration: The process of comparing a measurement instrument to a known standard to determine its accuracy.
- Verification: The process of confirming that a measurement instrument meets specified requirements.
- Adjustment: The process of modifying a measurement instrument to bring it into compliance with specifications.
- As Found: The condition of the equipment prior to any adjustments made during calibration.
- As Left: The condition of the equipment after adjustments have been made and verified.
- OOT (Out of Tolerance): A condition where a measurement falls outside of the specified acceptance criteria.
- Drift: The gradual change in a measurement instrument’s output over time.
- Traceability: The ability to verify the history, location, or application of an item by means of documented recorded identification.
- Measurement Uncertainty: A parameter that characterizes the range of values within which the true value of a measurement lies.
- Intermediate Check: A periodic check performed to ensure that a measurement instrument remains within specified limits between calibrations.

7. Standards & Tools
- Reference Standards Required: [TBD]
- Traceability Statement: Calibration will be traceable to ISO17025.
- Certificate Validity Check: Ensure all calibration certificates are valid and up to date.
8. Calibration Strategy
Calibration will follow the As Found then As Left logic. The minimum number of test points will be five, including endpoints (0 kN and 100 kN) and midpoints. Each point will have three replicate readings as a best practice.
9. Step-by-Step Procedure
- Preparation: Gather all necessary tools and reference standards.
- Stabilization: Allow the equipment to stabilize for a specified period.
- As Found checks and data capture: Record initial measurements at designated points.
- Adjustment rules: If OOT is detected, follow adjustment protocols; otherwise, escalate to QA.
- As Left verification: Confirm that adjustments bring the equipment within acceptance criteria.
- 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 for the Tablet Press Compression Force Sensor is ±2%. The error calculation formula is:
Error (%) = (Observed Value – True Value) / True Value × 100
Pass/Fail Logic: If the calculated error is within ±2%, the result is a pass; otherwise, it is a fail.
Rounding rule: [TBD]
11. Handling OOT / Failures
- Immediate containment: Tag the equipment and cease use.
- Notification & deviation initiation: Notify QA and initiate a deviation report.
- Impact assessment trigger: Define the impact window and review all affected results/batches.
- Recalibration after repair/adjustment: Ensure recalibration is performed post-adjustment.
- QA disposition placeholders: [TBD]
12. Records & Retention
- Logbook entries must include all calibration activities.
- Calibration report/certificate filing must be maintained for audit purposes.
- E-records if applicable: [TBD]
- Label content requirements: calibrated date, due date, by whom, status.
