3. Definitions
- Calibration: The process of comparing a measurement instrument against a standard to ensure 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 specified 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 results fall outside the specified acceptance criteria.
- Drift: The gradual change in the measurement output of an instrument 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 periodic check performed between calibrations to ensure continued accuracy.

- Standard ID: [TBD]
8. Calibration Strategy
Calibration will follow the As Found and As Left logic. The minimum number of points for calibration will be five, including endpoints (0 mL and 50 mL) and midpoints (25 mL). 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 graduated cylinder to stabilize in the calibration environment.
- As Found checks and data capture: Measure and record the volume at each calibration point.
- Adjustment rules: If OOT is detected, follow adjustment procedures if allowed; otherwise, escalate to QA.
- As Left verification: Measure and record the volume again to confirm adjustments.
- Labeling + documentation completion: Complete all required documentation and label the equipment accordingly.
Record all raw observations contemporaneously to ensure data integrity (ALCOA+).
10. Acceptance Criteria & Calculations
The acceptance criteria for the Graduated Cylinder 50 mL is Class A. The error calculation formula will be: Error = (Observed Value – True Value) / True Value x 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 the equipment and cease use.
- Notification & deviation initiation: Notify QA and initiate a deviation report.
- Impact assessment trigger: Define the impact window and review 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 as per company policy.
- e-Records if applicable: [TBD].
- Label content requirements: Include calibrated date, due date, technician name, and status.
