Calibration SOP

1. Purpose

The calibration of the Stability Chamber Controller Display Temperature is performed to ensure accurate temperature readings within the stability room, which is critical for maintaining the integrity of stability studies as per ICH guidelines. This calibration controls risks related to accuracy, patient safety, batch quality, and data integrity.

2. Scope

• Asset ID: CAL-0182
• Equipment Name/Type: Stability Chamber Controller Display Temp / Temp Controller
• Department/Area: Stability / Stability Room
• Process Use: ICH stability
• Parameter: Temperature
• Range: 0°C to 60°C
• Units: °C
• Calibration Frequency: 365 days

3. Definitions

• Calibration: The process of comparing a measurement instrument to a known standard to ensure accuracy.
• Verification: The process of confirming that a measurement instrument is functioning correctly.
• Adjustment: The act of correcting a measurement instrument to ensure it provides accurate readings.
• 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 the accuracy of a measurement 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 quick assessment of the instrument’s performance between full 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 records and ensure compliance.
• Owner Department: Ensure equipment is available and in good condition for calibration.
• External Service Provider: Conduct external calibrations as required.

6. Safety & Preconditions

• Ensure environmental controls are in place (temperature, humidity).
• Allow equipment to warm-up and stabilize as per manufacturer specifications.
• Maintain cleanliness of the calibration area and equipment.
• Check leveling of the equipment to ensure accurate readings.
• Verify power supply is stable and within specifications.

7. Standards & Tools

• Reference Standards Required: [TBD]
• Traceability Statement: ISO17025
• Certificate Validity Check: Ensure all calibration certificates are current and valid.
• Standard ID: [TBD]

8. Calibration Strategy

Calibration will follow the As Found and As Left logic. The minimum number of points for calibration will be 5, including endpoints (0°C and 60°C) and midpoints (15°C, 30°C, and 45°C). Each point will have 3 replicate readings to ensure accuracy.

9. Step-by-Step Procedure

1. Preparation: Gather all necessary tools and reference standards.
2. Stabilization: Allow the stability chamber to reach the desired temperature range.
3. As Found checks and data capture: Measure the temperature at each defined point and record the data contemporaneously.
4. Adjustment rules: If OOT is found, escalate to the QA department for further action.
5. As Left verification: Confirm that the instrument is within acceptance criteria after any adjustments.
6. Labeling + documentation completion: Complete all required documentation and label the equipment with calibration details.

10. Acceptance Criteria & Calculations

The acceptance criteria for this calibration is ±0.5°C. The error calculation formula is:

Error = Observed Value – True Value

Pass/Fail logic: If the absolute value of the error is within the acceptance criteria, the calibration passes; otherwise, it fails.

Rounding rule: [TBD]

11. Handling OOT / Failures

• Immediate containment: Tag the equipment and stop its 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 in the logbook.
• Calibration report/certificate filing: Maintain a file of all calibration reports and certificates.
• e-Records if applicable: [TBD]
• Label content requirements: Include calibrated date, due date, technician name, and status.
