Calibration SOP

1. Purpose

The calibration of the Balance Calibration Weight 500 g is performed to ensure the accuracy of mass measurements, which is critical for maintaining patient safety, ensuring batch quality, and upholding data integrity. Accurate weight measurements directly impact the formulation and dosing of pharmaceutical products, thereby controlling risks associated with incorrect dosing and potential patient harm.

2. Scope

  • Asset ID: CAL-0338
  • Equipment Name/Type: Balance Calibration Weight 500 g / Standard Weight
  • Department/Area: Calibration Lab / Metrology
  • Process Use: Mass standard
  • Parameter: Weight
  • Range: 500 g
  • Units: g
  • Calibration Frequency: 365 days

3. Definitions

  • Calibration: The process of comparing a measurement standard to a known reference to determine accuracy.
  • Verification: The process of confirming that a measurement system meets specified requirements.
  • Adjustment: The process of modifying a measurement system to bring it into compliance with specifications.
  • As Found: The condition of the equipment prior to any adjustments or corrections.
  • As Left: The condition of the equipment after calibration and 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 trace the history, application, or location of an item through 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 verification process conducted 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 calibration as per the defined schedule.

6. Safety & Preconditions

  • Ensure environmental controls are in place (temperature, humidity).
  • Allow equipment to warm-up/stabilize as per manufacturer recommendations.
  • Maintain cleanliness of the calibration area and equipment.
  • Check leveling of the balance calibration weight.
  • Verify power supply checks are completed.

7. Standards & Tools

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

8. Calibration Strategy

The calibration strategy will include the following:

  • Define As Found condition before any adjustments.
  • Define As Left condition after calibration.
  • Minimum number of points: At least 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 equipment to stabilize in the calibration environment.
  3. As Found checks and data capture: Record initial measurements and observations contemporaneously.
  4. Adjustment rules: If OOT is identified, escalate for further action as adjustments are not permitted.
  5. As Left verification: Confirm that the equipment meets specifications after calibration.
  6. Labeling + documentation completion: Complete all required documentation and label the equipment appropriately.

10. Acceptance Criteria & Calculations

The acceptance criteria for this calibration are defined as Class F1/E2. 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 equipment and stop use.
  • Notification & deviation initiation: Notify relevant personnel 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.
  • Calibration report/certificate filing: Maintain records of all calibration certificates.
  • e-Records if applicable: [TBD]
  • Label content requirements: Include calibrated date, due date, technician name, and status.
