Calibration SOP

1. Purpose

The calibration of the Graduated Cylinder 25 mL is performed to ensure accurate volume measurements, which are critical for maintaining patient safety and ensuring batch quality. Accurate measurements directly impact data integrity, thereby controlling risks associated with incorrect dosing and product quality.

2. Scope

  • Asset ID: CAL-0041
  • Equipment Name/Type: Graduated Cylinder 25 mL / Measuring Cylinder
  • Department/Area: QC / Glassware Room
  • Process Use: Volume measurement
  • Parameter: Volume
  • Range: 0 – 25 mL
  • Units: mL
  • Calibration Frequency: 365 days

3. Definitions

  • Calibration: The process of verifying and adjusting the accuracy of a measuring instrument.
  • Verification: The confirmation that a measuring instrument meets specified requirements.
  • Adjustment: The process of modifying a measuring instrument to bring it into compliance with specifications.
  • 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 instrument’s measurements fall outside the specified acceptance criteria.
  • Drift: The gradual change in measurement accuracy 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 associated with the result of a measurement that characterizes the dispersion of the values that could reasonably be attributed to the measurement.
  • Intermediate Check: A verification process performed between calibrations to ensure continued accuracy.

4. References

  • Company Metrology SOP [TBD]
  • ISO/IEC 17025 traceability via calibration certificates
  • ALCOA+ principles

5. Responsibilities

  • Technician/Metrology: Perform calibration and document results.
  • QC/QA Reviewer: Review calibration documentation and results.
  • Owner Department: Ensure equipment is available and accessible for calibration.
  • External Service Provider: Conduct external calibration as per the calibration type.

6. Safety & Preconditions

  • Ensure environmental controls are in place (temperature, humidity).
  • Allow equipment to warm up/stabilize as per manufacturer’s guidelines.
  • Ensure cleanliness of the graduated cylinder prior to calibration.
  • Check that the graduated cylinder is level before use.
  • Verify power supply if applicable [TBD].

7. Standards & Tools

  • Reference standards required: [TBD]
  • Traceability statement: ISO17025
  • Certificate validity check: Ensure calibration certificates are current and valid.
  • Standard ID placeholders: [TBD]

8. Calibration Strategy

Calibration will follow the As Found and As Left logic. At least 5 measurement points will be taken, including endpoints (0 mL and 25 mL) and midpoints (12.5 mL). Each point will have 3 replicate readings to ensure accuracy and reliability.

9. Step-by-Step Procedure

  1. Preparation: Gather all necessary tools and reference standards.
  2. Stabilization: Allow the graduated cylinder to reach ambient temperature.
  3. As Found checks and data capture: Measure volume at defined points and record data contemporaneously (ALCOA+).
  4. Adjustment rules: If OOT is identified, follow escalation procedures; adjustments should only be made if allowed.
  5. As Left verification: Re-measure at the same points to confirm adjustments.
  6. Labeling + documentation completion: Complete all required documentation and label the graduated cylinder with calibration details.

10. Acceptance Criteria & Calculations

Acceptance criteria: Class A

Error calculation formula: Error (%) = (Observed Value – True Value) / True Value * 100

Pass/Fail logic: If the error falls within the acceptance criteria, the calibration is considered a pass; otherwise, it is a fail.

Rounding rule placeholder: [TBD]

11. Handling OOT / Failures

  • Immediate containment: Tag the graduated cylinder 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 after any adjustments are made.
  • QA disposition placeholders: [TBD]

12. Records & Retention

  • Logbook entries: Document all calibration activities in the logbook.
  • Calibration report/certificate filing: Maintain records of calibration certificates.
  • e-records if applicable: [TBD]
  • Label content requirements: Include calibrated date, due date, technician name, and status.

    • Fill the graduated cylinder to each test point (0 mL, 6.25 mL, 12.5 mL, 18.75 mL, 25 mL).
    • Take three replicate readings for each test point and record the observed values.
  4. Calculating Error: Calculate the error for each observed value against the reference value.
  5. Evaluation: Compare the calculated errors to the acceptance criteria (Class A).
  6. Documentation: Complete the results table and ensure all data is recorded accurately.
