Calibration SOP

1. Purpose

The calibration of the Photo-stability Chamber Lux is performed to ensure accurate measurement of illuminance, which is critical for maintaining patient safety, ensuring batch quality, and preserving data integrity. Accurate light exposure is essential in stability studies to determine the shelf life and efficacy of pharmaceutical products.

2. Scope

  • Asset ID: CAL-0184
  • Equipment Name/Type: Photo-stability Chamber Lux / Photostability Lux Meter
  • Department/Area: Stability / Photostability
  • Process Use: Light exposure
  • Parameter: Illuminance
  • Range: 0 – 10000 lux
  • Units: lux
  • Calibration Frequency: 365 days

3. Definitions

  • Calibration: The process of comparing a measurement device against a known standard to ensure accuracy.
  • Verification: The process of confirming that a measurement device is functioning correctly.
  • Adjustment: The act of modifying a measurement device to bring it into alignment with a standard.
  • As Found: The state of the measurement device prior to any adjustments.
  • As Left: The state of the measurement device after adjustments have been made.
  • OOT (Out of Tolerance): A condition where the measurement device does not meet specified acceptance criteria.
  • Drift: The gradual change in a measurement device’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 periodic check of a measurement device to ensure it remains within specified limits between 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 documentation and results.
  • Owner Department: Ensure equipment is available and maintained.
  • 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 guidelines.
  • Maintain cleanliness of the equipment and surrounding area.
  • Check leveling of the equipment.
  • 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 within the range of 0 – 10000 lux.
  • Replicate readings: Perform 3 repeats at each point 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 recommendations.
  3. As Found checks and data capture: Record initial readings at all defined points.
  4. Adjustment rules: If OOT is detected, follow adjustment procedures if allowed; otherwise, escalate to QA.
  5. As Left verification: Record final readings after any adjustments.
  6. Labeling + documentation completion: Ensure all records are completed and raw observations are documented contemporaneously (ALCOA+).

10. Acceptance Criteria & Calculations

Acceptance criteria: As per method.

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

Pass/Fail Logic: If the error falls within acceptable limits, the calibration passes; otherwise, it fails.

Rounding rule: [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: Schedule recalibration as necessary.
  • QA disposition: [TBD]

12. Records & Retention

  • Logbook entries: Document all calibration activities.
  • Calibration report/certificate filing: Maintain records of calibration certificates.
  • e-Records if applicable: [TBD]
  • Label content requirements: Include calibrated date, due date, by whom, and status.
