Calibration SOP

1. Purpose

The calibration of the Flow Hood / Airflow Capture Hood is performed to ensure accurate airflow measurements within the Cleanroom environment. This is critical for maintaining compliance with Good Manufacturing Practices (GMP) and ensuring patient safety, batch quality, and data integrity. Accurate airflow measurements help mitigate risks associated with contamination and ensure that the cleanroom operates within specified parameters.

2. Scope

  • Asset ID: CAL-0251
  • Equipment Name/Type: Flow Hood / Airflow Capture Hood / Airflow Hood
  • Department/Area: HVAC / Cleanroom
  • Process Use: Airflow
  • Parameter: Flow
  • Range: 0 – 5000 m3/h
  • Units: m3/h
  • Calibration Frequency: 365 days

3. Definitions

  • Calibration: The process of comparing a measurement instrument to a known standard to ensure accuracy.
  • Verification: The confirmation that a measurement system is functioning correctly.
  • Adjustment: The process of modifying a measurement instrument to bring it into alignment with a standard.
  • As Found: The condition of the equipment prior to any adjustments made during calibration.
  • As Left: The condition of the equipment after calibration and any adjustments have been made.
  • OOT (Out of Tolerance): A condition where the measurement falls outside the established 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 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 for compliance.
  • Owner Department: Ensure equipment is available and properly maintained.
  • External Service Provider: Conduct external calibration as required.

6. Safety & Preconditions

  • Ensure environmental controls are in place (temperature, humidity).
  • Allow equipment to warm up/stabilize as per manufacturer guidelines.
  • Maintain cleanliness of the equipment and surrounding area.
  • Check that the equipment is level and stable.
  • Verify power supply is stable and within specifications.

7. Standards & Tools

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

8. Calibration Strategy

Calibration will follow the As Found and As Left logic:

  • Minimum number of points: At least 5 points including endpoints and midpoints across the range of 0 – 5000 m3/h.
  • Replicate readings at each point: 3 repeats as a best practice.

9. Step-by-Step Procedure

  1. Preparation: Gather all necessary tools and documentation.
  2. Stabilization: Allow the equipment to stabilize as per manufacturer guidelines.
  3. As Found checks and data capture: Record initial readings and observations contemporaneously (ALCOA+).
  4. Adjustment rules: If OOT is detected, follow adjustment protocols if allowed; otherwise, escalate to QA.
  5. As Left verification: Record final readings and ensure they meet acceptance criteria.
  6. Labeling + documentation completion: Complete all required documentation and label the equipment with calibration details.

10. Acceptance Criteria & Calculations

Acceptance criteria: ±3% of the measured value.

Error calculation formula: Error (%) = (Measured Value – True Value) / True Value × 100

Pass/Fail Logic: If the error falls within ±3%, mark as pass; otherwise, mark as fail.

Rounding rule: [TBD]

11. Handling OOT / Failures

  • Immediate containment: Tag equipment and stop use.
  • Notification & deviation initiation: Notify QA and initiate deviation process.
  • Impact assessment trigger: Define impact window and review of 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 for audit purposes.
  • e-Records if applicable: [TBD]
  • Label content requirements: Calibrated date, due date, by whom, status.
