Calibration SOP

1. Purpose

The calibration of the Flow Meter (Compressed Air) is performed to ensure accurate flow monitoring within the compressed air system. This calibration controls risks associated with inaccurate measurements that could impact patient safety, batch quality, and overall data integrity.

2. Scope

  • Asset ID: CAL-0082
  • Equipment Name/Type: Flow Meter (Compressed Air)
  • Department/Area: Utilities
  • Process Use: Flow monitoring
  • Parameter: Flow
  • Range: 0 – 500 Nm3/h
  • Units: Nm3/h
  • 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 measurement instrument prior to any adjustments being made.
  • As Left: The condition of the measurement 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 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 of a measurement lies.
  • Intermediate Check: A periodic verification of a measurement instrument’s performance between scheduled calibrations.

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 records and ensure compliance.
  • Owner Department: Ensure equipment is available and operational 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 for warm-up/stabilization of the equipment 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 Required: [TBD]
  • Traceability Statement: ISO17025
  • Certificate Validity Check: Ensure all reference standards are within their validity period.
  • Standard ID: [TBD]

8. Calibration Strategy

The 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 to 500 Nm3/h.
  • Replicate readings at each point: 3 repeats as a best practice.

9. Step-by-Step Procedure

  1. Preparation: Gather all necessary tools and reference standards.
  2. Stabilization: Allow the flow meter to stabilize before taking measurements.
  3. As Found checks and data capture: Record initial measurements and document results contemporaneously (ALCOA+).
  4. Adjustment rules: If OOT is detected, follow adjustment protocols; if not allowed, escalate to QA.
  5. As Left verification: Confirm that the flow meter is within tolerance after adjustments.
  6. Labeling + documentation completion: Ensure all records are filled out accurately and completely.

10. Acceptance Criteria & Calculations

Acceptance criteria: ±2%

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

Pass/Fail logic: If the error falls within ±2%, the calibration passes; otherwise, it fails.

Rounding rule: [TBD]

11. Handling OOT / Failures

  • Immediate containment: Tag the equipment 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 as necessary.
  • QA disposition placeholders: [TBD]

12. Records & Retention

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