Calibration SOP

1. Purpose

The calibration of the Inline Vacuum Transmitter is performed to ensure accurate pressure measurements within the specified range. This is critical for maintaining vacuum control during the API production process, thereby safeguarding patient safety, ensuring batch quality, and preserving data integrity.

2. Scope

• Asset ID: CAL-0202
• Equipment Name/Type: Inline Vacuum Transmitter / Vacuum Transmitter
• Department/Area: API / Dryer
• Process Use: Vacuum control
• Parameter: Pressure
• Range: -1 to 0 bar
• Units: bar
• Calibration Frequency: 365 days

3. Definitions

• Calibration: The process of configuring an instrument to provide a result for a sample within an acceptable range.
• Verification: The process of confirming that an instrument meets specified requirements.
• Adjustment: The process of modifying an instrument to bring it into compliance with specifications.
• 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 instrument’s measurements fall outside the specified acceptance criteria.
• Drift: The gradual change in an 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 associated with the result of a measurement 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 document results.
• QC/QA Reviewer: Review calibration documentation and results.
• Owner Department: Ensure equipment is available and in good condition for calibration.
• External Service Provider: Conduct calibration as per external calibration type.

6. Safety & Preconditions

• Ensure environmental controls are in place (temperature, humidity).
• Allow for warm-up/stabilization of the equipment as per manufacturer specifications.
• Maintain cleanliness of the equipment and surrounding area.
• Check leveling of the equipment.
• Verify power supply is stable and within specifications.

7. Standards & Tools

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

8. Calibration Strategy

Calibration will follow the As Found then As Left logic. The minimum number of test points will be five, including endpoints and midpoints within the specified range of -1 to 0 bar. 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 reference standards.
2. Stabilization: Allow the Inline Vacuum Transmitter to stabilize before taking measurements.
3. As Found checks and data capture: Record initial measurements and observations contemporaneously (ALCOA+).
4. Adjustment rules: If OOT is detected, follow escalation procedures as adjustments may not be allowed.
5. As Left verification: Confirm that the instrument is within specifications after any adjustments.
6. Labeling + documentation completion: Ensure all calibration records are completed accurately.

10. Acceptance Criteria & Calculations

Acceptance criteria for the Inline Vacuum Transmitter is ±1%. The error calculation formula is:

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

Pass/Fail logic: If the calculated error is within ±1%, the calibration passes; otherwise, it fails.

Rounding rule: [TBD]

11. Handling OOT / Failures

• Immediate containment: Tag equipment and stop use.
• Notification & deviation initiation: Inform relevant personnel of the OOT condition.
• Impact assessment trigger: Define impact window and review of affected results/batches.
• Recalibration after repair/adjustment: Schedule recalibration as necessary.
• QA disposition placeholders: [TBD]

12. Records & Retention

• Logbook entries: Document all calibration activities.
• Calibration report/certificate filing: Maintain records in accordance with company policy.
• e-Records if applicable: [TBD]
• Label content requirements: Include calibrated date, due date, technician name, and status.
