Calibration SOP

1. Purpose

The calibration of the Balance Calibration Weight 50 g is performed to ensure the accuracy of mass measurements, which is critical for maintaining patient safety, ensuring batch quality, and preserving data integrity. Accurate weight measurements directly impact the formulation and dosing of pharmaceutical products, thereby controlling risks associated with incorrect dosages.

2. Scope

  • Asset ID: CAL-0335
  • Equipment Name/Type: Balance Calibration Weight 50 g / Standard Weight
  • Department/Area: Calibration Lab / Metrology
  • Process Use: Mass standard
  • Parameter: Weight
  • Range: 50 g
  • Units: g
  • Calibration Frequency: 365 days

3. Definitions

  • Calibration: The process of verifying and adjusting the accuracy of a measurement instrument against a known standard.
  • Verification: The process of confirming that an instrument meets specified requirements.
  • Adjustment: The act 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 falls 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 expected to lie.
  • Intermediate Check: A periodic assessment of an instrument’s performance between 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 for warm-up/stabilization of the equipment as per manufacturer guidelines.
  • Maintain cleanliness of the calibration area and equipment.
  • Check leveling of the balance before use.
  • Verify power supply stability and functionality.

7. Standards & Tools

  • Reference Standards Required: ISO17025 certified calibration weights.
  • Traceability Statement: Calibration is traceable to ISO17025.
  • Certificate Validity Check: Ensure calibration certificates are current and valid.
  • Standard ID: [TBD]

8. Calibration Strategy

Calibration will follow the As Found and As Left logic:

  • Minimum number of points: 5 points including endpoints and midpoints.
  • 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 balance to stabilize before calibration.
  3. As Found checks and data capture: Record initial measurements before any adjustments.
  4. Adjustment rules: If OOT is found, escalate for further investigation; adjustments should only be made if allowed.
  5. As Left verification: Confirm that the instrument is within tolerance after adjustments.
  6. Labeling + documentation completion: Complete all required documentation and label the equipment accordingly.

Record raw observations contemporaneously to ensure data integrity (ALCOA+).

10. Acceptance Criteria & Calculations

Acceptance criteria: Class F1/E2.

Error calculation formula: 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 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: 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.
