Calibration SOP

1. Purpose

The calibration of the Standard Weights Set F1 is performed to ensure the accuracy of mass measurements within the Calibration Lab. This is critical for maintaining patient safety, ensuring batch quality, and preserving data integrity in compliance with GMP standards. Accurate weight measurements are essential to prevent errors in formulation and dosing, which could impact product safety and efficacy.

2. Scope

  • Asset ID: CAL-0281
  • Equipment Name/Type: Standard Weights Set F1 / 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 instrument to 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 instrument prior to any adjustments being made.
  • As Left: The condition of the 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 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 periodic check of an instrument to ensure it remains within specified limits between full calibrations.

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 results and documentation.
  • Owner Department: Ensure compliance with calibration schedules.
  • 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 for calibration include:

  • Standard Weights compliant with F1 Class.

Traceability: ISO17025

Certificate Validity Check: Ensure all reference standards have valid calibration certificates.

8. Calibration Strategy

Calibration will follow the As Found and As Left logic:

  • Minimum number of points: 5 points including endpoints (1 g, 1000 g) and midpoints.
  • Replicate readings at each point: 3 repeats are recommended for accuracy.

9. Step-by-Step Procedure

  1. Preparation: Gather all necessary tools and reference standards.
  2. Stabilization: Allow the equipment to reach operating conditions.
  3. As Found checks and data capture: Measure weights and record results contemporaneously.
  4. Adjustment rules: If OOT is found, follow escalation procedures; adjustments are only permitted if allowed.
  5. As Left verification: Confirm that the adjustments bring the equipment within tolerance.
  6. Labeling + documentation completion: Ensure all records are filled out accurately and completely.

10. Acceptance Criteria & Calculations

Acceptance Criteria: F1 Class

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

Pass/Fail Logic: If error is within acceptance criteria, pass; otherwise, fail.

Rounding Rule: [TBD]

11. Handling OOT / Failures

  • Immediate containment: Tag equipment and stop use.
  • Notification & deviation initiation: Notify relevant personnel of 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: Document all calibration activities.
  • Calibration report/certificate filing: Maintain records of calibration certificates.
  • e-Records if applicable: [TBD]
  • Label Content Requirements: Calibrated date, due date, by whom, status.
