Calibration SOP

1. Purpose

The calibration of the Standard Weights Set E2 is performed to ensure the accuracy of mass measurements, which is critical for maintaining patient safety, ensuring batch quality, and upholding data integrity in compliance with GMP standards. Accurate weight measurements are essential to prevent dosage errors that could impact product efficacy and safety.

2. Scope

  • Asset ID: CAL-0280
  • Equipment Name/Type: Standard Weights Set E2 / Standard Weights
  • Department/Area: Calibration Lab / Metrology
  • Process Use: Mass standard
  • Parameter: Weight
  • Range: 1 g to 1000 g
  • Units: g
  • Calibration Frequency: 365 days

3. Definitions

  • Calibration: The process of comparing a measurement standard to a known reference to determine its accuracy.
  • Verification: The process of confirming that a measurement system is functioning correctly.
  • Adjustment: The process of modifying a measurement system to bring it into alignment with a standard.
  • As Found: The condition of the equipment prior to any adjustments being made.
  • As Left: The condition of the equipment 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 a measurement system’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 associated with the result of a measurement that characterizes the dispersion of the values that could reasonably be attributed to the measurement.
  • Intermediate Check: A periodic verification of measurement equipment 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 in good condition for calibration.
  • 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 recommendations.
  • Maintain cleanliness of the calibration area and equipment.
  • Check leveling of the equipment before use.
  • Verify power supply stability and functionality.

7. Standards & Tools

  • Reference standards required: E2 Class weights.
  • Traceability: ISO17025
  • Certificate validity check: Ensure all calibration certificates are current and valid.
  • Standard ID placeholders: [TBD]

8. Calibration Strategy

Calibration will follow the As Found then As Left logic. The minimum number of points for calibration will be five, including endpoints and midpoints within the specified range of 1 g to 1000 g. Each point will have three replicate readings to ensure accuracy and reliability.

9. Step-by-Step Procedure

  1. Preparation: Gather all necessary tools and reference standards.
  2. Stabilization: Allow the equipment to stabilize in the calibration environment.
  3. As Found checks and data capture: Measure the weights and record the initial readings.
  4. Adjustment rules: If any readings are OOT, escalate for adjustment as per SOP.
  5. As Left verification: Measure again after any adjustments and record the final readings.
  6. Labeling + documentation completion: Label the equipment with calibration details and complete all documentation contemporaneously to maintain ALCOA+ integrity.

10. Acceptance Criteria & Calculations

The acceptance criteria for this calibration is E2 Class. The error calculation formula is:

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

Pass/Fail logic: If the error falls within the acceptance criteria, 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 QA and initiate a deviation report.
  • 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 in the logbook.
  • Calibration report/certificate filing: Maintain a file of all calibration certificates.
  • e-records if applicable: [TBD]
  • Label content requirements: Include calibrated date, due date, technician name, and status.

Stepwise Instructions

  1. Preparation: Ensure the calibration area is clean and free from contaminants. Gather all necessary equipment and documentation.
  2. Stabilization: Allow the Standard Weights Set E2 to acclimate to the environmental conditions for at least [TBD] minutes.
  3. Performing Readings:
    • Place the weight on the balance.
    • Record the observed weight for each test point in the results table.
    • Take three replicate readings for each test point and calculate the average.
  4. Calculating Error: Determine the error by subtracting the reference value from the observed value.
  5. Evaluation: Compare the error against the acceptance criteria. Mark as Pass or Fail.
  6. Documentation: Complete the results table and ensure all data is recorded accurately, maintaining ALCOA+ principles.

Deviation Instruction for OOT

If any observed value falls outside the acceptance criteria:

  • Stop use of the asset immediately.
  • Notify the supervisor and QA.
  • Open a deviation report.
  • Quarantine impacted results window: [TBD]
