Calibration SOP

1. Purpose

The calibration of the Water System Flow Transmitter is performed to ensure accurate measurement of flow rates, which is critical for maintaining patient safety, ensuring batch quality, and preserving data integrity. Accurate flow measurements directly impact the quality of water used in pharmaceutical processes, thereby controlling risks associated with product contamination and non-compliance with regulatory standards.

2. Scope

  • Asset ID: CAL-0322
  • Equipment Name/Type: Water System Flow Transmitter / Flow Transmitter
  • Department/Area: Utilities / PW/WFI
  • Process Use: Flow
  • Parameter: Flow
  • Range: 0 – 500 L/min
  • Units: L/min
  • 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 is functioning correctly.
  • Adjustment: The process of modifying a measurement instrument to bring it within specified limits.
  • 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 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 verification process conducted between calibrations to ensure ongoing 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 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 for warm-up/stabilization of the equipment as per manufacturer guidelines.
  • Maintain cleanliness of the equipment and surrounding area.
  • Check leveling of the equipment to ensure accurate measurements.
  • Verify power supply checks are completed prior to calibration.

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:

  • Minimum number of points: At least 5 points including endpoints and midpoints within the range of 0 to 500 L/min.
  • Replicate readings at each point: 3 repeats are recommended as a best practice.

9. Step-by-Step Procedure

  1. Preparation: Gather all necessary tools and reference standards.
  2. Stabilization: Allow the equipment to stabilize as per manufacturer guidelines.
  3. As Found checks and data capture: Record initial measurements and observations contemporaneously (ALCOA+).
  4. Adjustment rules: If OOT is identified, follow escalation procedures; adjustments are only permitted if allowed.
  5. As Left verification: Confirm that the equipment is functioning within specifications after adjustments.
  6. Labeling + documentation completion: Ensure all records are filled out accurately and completely.

10. Acceptance Criteria & Calculations

Acceptance criteria: ±1%

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

Pass/Fail Logic: If the error falls within ±1%, the calibration is considered a pass; otherwise, it is a fail.

Rounding rule placeholder: [TBD]

11. Handling OOT / Failures

  • Immediate containment: Tag equipment and stop use.
  • Notification & deviation initiation: Notify relevant personnel of the OOT condition.
  • 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: Maintain detailed logbook entries for all calibration activities.
  • Calibration report/certificate filing: Ensure all calibration reports are filed appropriately.
  • e-Records if applicable: [TBD]
  • Label content requirements: Include calibrated date, due date, technician name, and status.
