Calibration SOP

1. Purpose

The calibration of the Torque Tester (Cap torque) is performed to ensure accurate measurement of torque applied to caps during packaging. This is critical for maintaining batch quality, ensuring patient safety, and preserving data integrity. Inaccurate torque measurements can lead to improper sealing, resulting in compromised product quality and potential risks to patient safety.

2. Scope

• Asset ID: CAL-0265
• Equipment Name/Type: Torque Tester (Cap torque)
• Department/Area: Packaging
• Process Use: Cap torque
• Parameter: Torque
• Range: 0 – 300 Ncm
• Units: Ncm
• Calibration Frequency: 180 days

3. Definitions

• Calibration: The process of comparing a measurement instrument to a 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 meets specified standards.
• As Found: The condition of the instrument prior to any adjustments made during calibration.
• As Left: The condition of the instrument after adjustments have been made and verified.
• OOT (Out of Tolerance): A condition where the measurement falls outside the specified acceptance criteria.
• Drift: The gradual change in a measurement instrument’s performance 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 of a measurement lies.
• 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 document results.
• QC/QA Reviewer: Review calibration documentation and results.
• Owner Department: Ensure equipment is available and maintained.
• External Service Provider: Conduct external calibration as per schedule.

6. Safety & Preconditions

• Ensure environmental controls are in place (temperature, humidity).
• Allow equipment to warm-up and stabilize as per manufacturer guidelines.
• Maintain cleanliness of the equipment and surrounding area.
• Check that the equipment is level and stable.
• 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 and As Left logic. The minimum number of test points will be 5, including endpoints and midpoints, across the specified range of 0 to 300 Ncm. Each point will have 3 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 Torque Tester to stabilize in the operating environment.
3. As Found checks and data capture: Measure torque at defined points and record raw observations contemporaneously.
4. Adjustment rules: If OOT is detected, follow adjustment protocols; if not allowed, escalate to QA.
5. As Left verification: Re-measure to confirm adjustments are within specifications.
6. Labeling + documentation completion: Complete all required documentation and label the equipment with calibration details.

10. Acceptance Criteria & Calculations

Acceptance criteria: ±2% of the specified torque value. The error calculation formula is:

Error (%) = [(Observed Value – True Value) / True Value] x 100

Pass/Fail logic: If the error is within ±2%, the result is a pass; otherwise, it is a fail.

Rounding rule: [TBD]

11. Handling OOT / Failures

• Immediate containment: Tag the equipment and stop its use.
• Notification & deviation initiation: Notify relevant personnel and initiate a deviation report.
• Impact assessment trigger: Assess the impact on results/batches produced since the last calibration.
• 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 records of calibration certificates.
• e-Records if applicable: [TBD]
• Label content requirements: Include calibrated date, due date, technician name, and status.
