Calibration SOP

1. Purpose

The calibration of the Graduated Cylinder 500 mL is performed to ensure accurate volume measurements, which are critical for maintaining batch quality and patient safety. Accurate measurements help mitigate risks associated with incorrect dosing and ensure compliance with regulatory standards, thereby supporting data integrity throughout the quality control process.

2. Scope

  • Asset ID: CAL-0045
  • Equipment Name/Type: Graduated Cylinder 500 mL / Measuring Cylinder
  • Department/Area: QC / Glassware Room
  • Process Use: Volume measurement
  • Parameter: Volume
  • Range: 0 mL to 500 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 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 equipment at the time of calibration before any adjustments are made.
  • As Left: The condition of the equipment after calibration and any necessary adjustments have been made.
  • OOT (Out of Tolerance): A condition where the measurement results fall outside the established 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 of a measurement lies.
  • Intermediate Check: A verification process performed between calibrations to ensure ongoing accuracy.

  • 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 maintained.
  • 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 guidelines.
  • Ensure cleanliness of the graduated cylinder before use.
  • Verify that the graduated cylinder is level before calibration.

7. Standards & Tools

  • Reference standards required: [TBD]
  • Traceability statement: ISO17025
  • Certificate validity check: Ensure all 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 five, including endpoints (0 mL and 500 mL) and midpoints (e.g., 250 mL). Each point will have three replicate readings to ensure accuracy and reliability.

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 the volume at specified points and record observations contemporaneously (ALCOA+).
  4. Adjustment rules: If OOT is detected, follow the adjustment protocol if allowed; otherwise, escalate the issue.
  5. As Left verification: Confirm that the graduated cylinder meets acceptance criteria after adjustments.
  6. Labeling + documentation completion: Complete all necessary documentation and label the equipment accordingly.

10. Acceptance Criteria & Calculations

Acceptance criteria for the Graduated Cylinder 500 mL is Class A. The error calculation formula is as follows:

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 placeholder: [TBD]

11. Handling OOT / Failures

  • Immediate containment: Tag the graduated cylinder and stop its use.
  • Notification & deviation initiation: Notify relevant personnel and initiate a deviation report.
  • Impact assessment trigger: Define the impact window and review affected results/batches.
  • Recalibration after repair/adjustment: Schedule recalibration as necessary.
  • QA disposition placeholders: [TBD]

12. Records & Retention

  • Logbook entries: Record all calibration activities in the logbook.
  • Calibration report/certificate filing: Maintain all calibration certificates in an accessible location.
  • e-Records if applicable: [TBD]
  • Label content requirements: Include calibrated date, due date, technician name, and status.
