Calibration SOP

1. Purpose

The calibration of the Laminar Airflow Velocity meter is performed to ensure accurate measurement of airflow velocity in the cleanroom environment. This is critical for maintaining aseptic conditions during microbiological processes, thereby controlling risks associated with patient safety, batch quality, and data integrity.

2. Scope

  • Asset ID: CAL-0170
  • Equipment Name/Type: Laminar Airflow Velocity / Air Velocity Meter
  • Department/Area: Microbiology / Cleanroom
  • Process Use: Aseptic work
  • Parameter: Velocity
  • Range: 0 to 1 m/s
  • Units: m/s
  • Calibration Frequency: 365 days

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 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 falls outside the defined acceptance criteria.
  • Drift: The gradual change in the output of a measurement instrument over time.
  • Traceability: The ability to trace the measurement results back to national or international standards.
  • Measurement Uncertainty: A parameter that characterizes the dispersion of values attributed to a measurement.
  • Intermediate Check: A periodic check performed to ensure the ongoing accuracy of a measurement instrument.

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 in good condition for calibration.
  • External Service Provider: Conduct external calibration as per schedule.

6. Safety & Preconditions

  • Ensure environmental controls are in place (temperature, humidity).
  • Allow equipment to warm up and stabilize as per manufacturer recommendations.
  • Maintain cleanliness of the cleanroom environment.
  • Verify equipment is level and stable before calibration.
  • Check power supply to ensure it is functioning correctly.

7. Standards & Tools

  • Reference Standards Required: [TBD]
  • Traceability Statement: ISO17025
  • Certificate Validity Check: Ensure calibration certificates are current and valid.
  • Standard ID: [TBD]

8. Calibration Strategy

Calibration will follow the As Found and As Left logic. The minimum number of test points will be 5, including endpoints and midpoints of the range (0 to 1 m/s). Each point will be measured in triplicate to ensure accuracy and reliability.

9. Step-by-Step Procedure

  1. Preparation: Gather all necessary tools and reference standards.
  2. Stabilization: Allow the equipment to stabilize in the cleanroom environment.
  3. As Found checks and data capture: Measure airflow velocity at defined points and record results contemporaneously.
  4. Adjustment rules: If OOT is detected, escalate for adjustment as per SOP.
  5. As Left verification: Re-measure to confirm adjustments bring the instrument within acceptance criteria.
  6. Labeling + documentation completion: Complete all required documentation and label the equipment with calibration details.

10. Acceptance Criteria & Calculations

Acceptance criteria for the Laminar Airflow Velocity meter is ±0.05 m/s. The error calculation formula is:

Error = Observed Value – True Value

Pass/Fail logic: If the absolute value of the error is within the acceptance criteria, the calibration passes; otherwise, it fails.

Rounding rule: [TBD]

11. Handling OOT / Failures

  • Immediate containment: Tag equipment and stop use until resolved.
  • Notification & deviation initiation: Notify QA and initiate a deviation report.
  • Impact assessment trigger: Assess impact on results/batches within the defined impact window.
  • Recalibration after repair/adjustment: Schedule recalibration once issues are resolved.
  • QA disposition placeholders: [TBD]

12. Records & Retention

  • Logbook entries: Document all calibration activities.
  • Calibration report/certificate filing: Maintain records for audit purposes.
  • e-Records if applicable: [TBD]
  • Label content requirements: Include calibrated date, due date, technician name, and status.
