Calibration SOP
1. Purpose
The calibration of the Torque Wrench (Packaging) is performed to ensure accurate torque control during the packaging process. This is critical for maintaining batch quality and patient safety, as improper torque can lead to product failure or compromised integrity. Calibration also supports data integrity by ensuring that measurements are reliable and traceable.

3. Definitions
- Calibration: The process of comparing a measurement instrument against a known standard to determine its accuracy.
- Verification: The process of confirming that a measurement instrument meets specified requirements.
- Adjustment: The act of modifying a measurement instrument to bring it into compliance with specified standards.
- As Found: The condition of the instrument prior to any adjustments being made.
- As Left: The condition of the instrument after adjustments have been made.
- OOT (Out of Tolerance): A condition where the measurement falls outside 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 is asserted to lie.
- Intermediate Check: A verification process conducted between scheduled calibrations to ensure continued accuracy.

8. Calibration Strategy
Calibration will follow the As Found then As Left logic. The minimum number of points for calibration will be five, including endpoints and midpoints within the specified range of 0 to 50 Nm. It is recommended to take three replicate readings at each point to ensure accuracy.
9. Step-by-Step Procedure
- Preparation: Gather all necessary tools and reference standards.
- Stabilization: Allow the torque wrench to stabilize in the calibration environment.
- As Found checks and data capture: Measure torque at designated points and record observations contemporaneously (ALCOA+).
- Adjustment rules: If OOT is found, escalate for adjustment as per company policy.
- As Left verification: Re-measure torque after adjustments and record results.
- Labeling + documentation completion: Complete all required documentation and label the equipment appropriately.
10. Acceptance Criteria & Calculations
Acceptance criteria: ±4% of the target value. The error calculation formula is as follows:
Error (%) = [(Observed Value – True Value) / True Value] x 100
Pass/Fail Logic: If the error falls within ±4%, the result is a pass; otherwise, it is a fail.
Rounding rule: [TBD]
11. Handling OOT / Failures
- Immediate containment: Tag the equipment and stop its use.
- Notification & deviation initiation: Notify relevant personnel and initiate a deviation report.
- Impact assessment trigger: Define the impact window and review affected results/batches.
- Recalibration after repair/adjustment: Schedule recalibration once adjustments are made.
- 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.
