Calibration SOP

1. Purpose

The calibration of the Standard Weights Set F2 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 and ensure the reliability of analytical results.

2. Scope

  • Asset ID: CAL-0282
  • Equipment Name/Type: Standard Weights Set F2 / 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 against 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 standards.
  • As Found: The condition of the equipment prior to any adjustments made during calibration.
  • As Left: The condition of the equipment after calibration and any necessary adjustments.
  • OOT (Out of Tolerance): A condition where the measurement results fall outside the specified acceptance criteria.
  • Drift: The gradual change in a measurement instrument’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 of a measurement lies.
  • 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 results and documentation.
  • Owner Department: Ensure equipment is available and in proper condition for calibration.
  • External Service Provider: Conduct external calibration as required.

6. Safety & Preconditions

  • Ensure environmental controls are in place (temperature, humidity).
  • Allow adequate warm-up/stabilization time for the equipment.
  • Maintain cleanliness of the calibration area and equipment.
  • Check leveling of the equipment.
  • Verify power supply stability.

7. Standards & Tools

  • Reference standards required: F2 Class weights.
  • Traceability: ISO17025
  • Certificate validity check: Ensure calibration certificates are current and valid.
  • Standard ID placeholders: [TBD]

8. Calibration Strategy

Calibration will follow the As Found and As Left logic. The minimum number of points for calibration will be five, including endpoints and midpoints within the range of 1 g to 1000 g. It is recommended to take three replicate readings at each point to ensure accuracy.

9. Step-by-Step Procedure

  1. Preparation: Gather all necessary tools and documentation.
  2. Stabilization: Allow the equipment to stabilize in the calibration environment.
  3. As Found checks and data capture: Measure and record the weight of each standard weight.
  4. Adjustment rules: If any measurements are OOT, escalate for adjustment as per SOP.
  5. As Left verification: Measure and record the weight of each standard weight post-adjustment.
  6. Labeling + documentation completion: Label the equipment and complete all required documentation.

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

10. Acceptance Criteria & Calculations

The acceptance criteria for the Standard Weights Set F2 is F2 Class. The error calculation formula is as follows:

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

Pass/Fail logic: If the error is 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 deviation process.
  • Impact assessment trigger: Define impact window and review of affected results/batches.
  • Recalibration after repair/adjustment: Ensure recalibration is performed after any adjustments.
  • 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: Include calibrated date, due date, by whom, and status.
