Calibration SOP

1. Purpose

The calibration of the Vacuum Gauge (-1 to 0 bar) is performed to ensure accurate pressure measurements during the vacuum monitoring process in the Production department. This calibration controls risks associated with inaccurate pressure readings, which can impact patient safety, batch quality, and overall data integrity.

2. Scope

• Asset ID: CAL-0073
• Equipment Name/Type: Vacuum Gauge
• Department/Area: Production / Drying/Vacuum
• Process Use: Vacuum monitoring
• Parameter: Pressure
• Range: -1 to 0 bar
• Units: bar
• Calibration Frequency: 365 days

3. Definitions

• Calibration: The process of verifying and adjusting the accuracy of a measurement instrument.
• Verification: The confirmation that a measurement instrument meets specified requirements.
• Adjustment: The process of modifying a measurement instrument to bring it into compliance with specified standards.
• 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 defined acceptance criteria.
• Drift: The gradual change in a measurement instrument’s output over time.
• Traceability: The ability to trace the measurement results back to national or international standards.
• Measurement Uncertainty: A parameter that characterizes the range of values within which the true value is expected to lie.
• Intermediate Check: A periodic verification of the instrument’s performance between calibrations.

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 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 and stabilize before calibration.
• Maintain cleanliness of the equipment and surrounding area.
• Check that the equipment is level and properly positioned.
• Verify power supply is stable and within required specifications.

7. Standards & Tools

• Reference standards required: [TBD]
• Traceability statement: ISO17025
• Certificate validity check: [TBD]

8. Calibration Strategy

The calibration will follow the As Found and As Left logic:

• Minimum number of points: At least 5 points, including endpoints (-1 bar, 0 bar) and midpoints.
• Replicate readings: 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 Vacuum Gauge to stabilize in the operating environment.
3. As Found checks and data capture: Record initial readings at defined points.
4. Adjustment rules: If OOT, follow adjustment procedures; if not allowed, escalate to QA.
5. As Left verification: Confirm readings post-adjustment to ensure compliance.
6. Labeling + documentation completion: Complete all required documentation and label the equipment.

Record raw observations contemporaneously to ensure ALCOA+ compliance.

10. Acceptance Criteria & Calculations

Acceptance criteria: ±1%

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

Pass/Fail logic: If error falls within ±1%, mark as pass; otherwise, mark as fail.

Rounding rule: [TBD]

11. Handling OOT / Failures

• Immediate containment: Tag equipment and stop use.
• Notification & deviation initiation: Inform relevant personnel of OOT condition.
• Impact assessment trigger: Define impact window and review of affected results/batches.
• Recalibration after repair/adjustment: Ensure recalibration is performed before returning to service.
• QA disposition: [TBD]

12. Records & Retention

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