Calibration SOP

1. Purpose

The calibration of the Volumetric Flask 250 mL is performed to ensure accurate volume measurements during solution preparation in the QC department. This calibration controls risks associated with accuracy, patient safety, batch quality, and data integrity, thereby ensuring compliance with regulatory standards.

2. Scope

  • Asset ID: CAL-0037
  • Equipment Name/Type: Volumetric Flask 250 mL / Volumetric Flask
  • Department/Area: QC / Glassware Room
  • Process Use: Solution prep
  • Parameter: Volume
  • Range: 0 – 250 mL
  • Units: mL
  • Calibration Frequency: 365 days

3. Definitions

  • Calibration: The process of comparing a measurement instrument against a standard to determine its accuracy.
  • Verification: The process of confirming that a measurement instrument meets specified requirements.
  • Adjustment: The act of modifying a measurement instrument to bring it into compliance with specifications.
  • As Found: The condition of the equipment at the time of calibration before any adjustments.
  • As Left: The condition of the equipment after calibration and any necessary adjustments.
  • OOT (Out of Tolerance): A condition where the measurement falls outside the specified acceptance criteria.
  • Drift: The gradual change in a measurement instrument’s accuracy 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 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 required.

6. Safety & Preconditions

  • Ensure environmental controls are in place (temperature, humidity).
  • Allow equipment to warm up/stabilize as per manufacturer recommendations.
  • Verify cleanliness of the volumetric flask before use.
  • Check leveling of the equipment.
  • Confirm power supply checks are completed [TBD].

7. Standards & Tools

  • Reference Standards Required: Class A volumetric standards.
  • Traceability Statement: Calibration traceable to ISO17025.
  • Certificate Validity Check: Ensure 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 5, including endpoints (0 mL and 250 mL) and midpoints (125 mL). Each point will have 3 replicate readings as a best practice.

9. Step-by-Step Procedure

  1. Preparation: Gather all necessary equipment and reference standards.
  2. Stabilization: Allow the volumetric flask to stabilize in the calibration environment.
  3. As Found checks and data capture: Measure the volume at each defined point and record the data contemporaneously (ALCOA+).
  4. Adjustment rules: If OOT is detected, follow adjustment procedures if allowed; otherwise, escalate to QA.
  5. As Left verification: Measure again to confirm the flask is within tolerance after any adjustments.
  6. Labeling + documentation completion: Complete all required documentation and label the equipment appropriately.

10. Acceptance Criteria & Calculations

The acceptance criteria for the volumetric flask is Class A. The error calculation formula is:

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

Pass/Fail logic: If the error is within the acceptance criteria, the calibration is considered a pass; otherwise, it is a fail.

Rounding rule: [TBD].

11. Handling OOT / Failures

  • Immediate containment: Tag the equipment and stop use.
  • Notification & deviation initiation: Notify QA and initiate a deviation report.
  • Impact assessment trigger: Define the impact window and review 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: Include calibrated date, due date, by whom, and status.
