Calibration SOP

1. Purpose

The calibration of the Biosafety Cabinet Air Velocity Meter is performed to ensure accurate measurement of air velocity during aseptic work. This calibration controls risks related to patient safety, batch quality, and data integrity by ensuring that the equipment operates within specified parameters.

2. Scope

  • Asset ID: CAL-0171
  • Equipment Name/Type: Biosafety Cabinet Air Velocity Meter
  • Department/Area: Microbiology / BSC Room
  • 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 to a known standard to ensure accuracy.
  • Verification: The process of confirming that an instrument meets specified requirements.
  • Adjustment: The process of modifying an 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 measurement falls 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 check 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 maintain records.
  • QC/QA Reviewer: Review calibration records and ensure compliance.
  • Owner Department: Ensure equipment is available and maintained.
  • External Service Provider: Conduct external calibrations as required.

6. Safety & Preconditions

  • Ensure environmental controls are in place (temperature, humidity).
  • Allow equipment to warm up and stabilize as per manufacturer guidelines.
  • Maintain cleanliness of the area and equipment.
  • Check leveling of the equipment.
  • Verify power supply stability.

7. Standards & Tools

  • Reference standards required: [TBD]
  • Traceability statement: ISO17025
  • Certificate validity check: [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 within the range of 0 to 1 m/s.
  • Replicate readings: 3 repeats at each point as a best practice.

9. Step-by-Step Procedure

  1. Preparation: Gather all necessary tools and documentation.
  2. Stabilization: Allow the equipment to stabilize in the operating environment.
  3. As Found checks and data capture: Record initial readings before any adjustments.
  4. Adjustment rules: If OOT is detected, follow adjustment protocols; otherwise, escalate to QA.
  5. As Left verification: Confirm that the equipment is within specifications after adjustments.
  6. Labeling + documentation completion: Ensure all records are filled out and labels are affixed.

Record raw observations contemporaneously to ensure data integrity (ALCOA+).

10. Acceptance Criteria & Calculations

Acceptance criteria: ±0.05 m/s

Error calculation formula: Error = Observed Value – True Value

Pass/Fail logic: If the absolute value of Error is less than or equal to 0.05 m/s, then Pass; otherwise, Fail.

Rounding rule: [TBD]

11. Handling OOT / Failures

  • Immediate containment: Tag equipment and stop use.
  • Notification & deviation initiation: Notify QA and document the deviation.
  • Impact assessment trigger: Define impact window and review of affected results/batches.
  • Recalibration after repair/adjustment: Ensure recalibration is performed before returning to service.
  • QA disposition placeholders: [TBD]

12. Records & Retention

  • Logbook entries: Document all calibration activities.
  • Calibration report/certificate filing: Maintain all calibration certificates in a secure location.
  • e-Records if applicable: [TBD]
  • Label content requirements: Calibrated date, due date, by whom, status.
