Calibration SOP

1. Purpose

The calibration of the Graduated Cylinder 250 mL is performed to ensure accurate volume measurements, which are critical for maintaining patient safety, ensuring batch quality, and preserving data integrity. Accurate measurements prevent deviations that could compromise product quality and regulatory compliance.

2. Scope

  • Asset ID: CAL-0044
  • Equipment Name/Type: Graduated Cylinder 250 mL / Measuring Cylinder
  • Department/Area: QC / Glassware Room
  • Process Use: Volume measurement
  • Parameter: Volume
  • Range: 0 mL to 250 mL
  • Units: mL
  • 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 is functioning correctly.
  • Adjustment: The process of modifying a measurement instrument to bring it into compliance with a standard.
  • As Found: The condition of the instrument prior to any adjustments.
  • 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 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 is asserted to lie.
  • Intermediate Check: A verification process conducted between calibrations to ensure ongoing 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 accessible 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.
  • Ensure cleanliness of the graduated cylinder prior to calibration.
  • Check that the graduated cylinder is level before use.
  • Verify power supply checks if applicable [TBD].

7. Standards & Tools

  • Reference standards required: Class A volumetric standards.
  • Traceability: ISO17025
  • Certificate validity check: Ensure all reference standards are within their calibration validity period.
  • Standard ID: [TBD]

8. Calibration Strategy

Calibration will follow the As Found and As Left logic:

  • Minimum number of points: At least 5 points including endpoints (0 mL, 250 mL) and midpoints (125 mL).
  • Replicate readings: Perform 3 repeats at each point as a best practice.

9. Step-by-Step Procedure

  1. Preparation: Gather all necessary tools and reference standards.
  2. Stabilization: Allow the graduated cylinder to acclimate to the calibration environment.
  3. As Found checks and data capture: Measure and record the volume at each calibration point.
  4. Adjustment rules: If any measurements are OOT, escalate for adjustment as per SOP.
  5. As Left verification: Re-measure to confirm adjustments are within acceptance criteria.
  6. Labeling + documentation completion: Complete all required documentation and label the equipment.

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

10. Acceptance Criteria & Calculations

Acceptance criteria: Class A

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 QA and initiate deviation process.
  • Impact assessment trigger: Define impact window and review of affected results/batches.
  • Recalibration after repair/adjustment: Schedule recalibration post-adjustment.
  • QA disposition placeholders: [TBD]

12. Records & Retention

  • Logbook entries: Document all calibration activities.
  • Calibration report/certificate filing: Maintain records as per company policy.
  • e-records if applicable: [TBD]
  • Label content requirements: Calibrated date, due date, by whom, status.
