Calibration SOP

1. Purpose

The calibration of the Colorimeter is performed to ensure accurate measurement of color, which is critical for maintaining batch quality and ensuring patient safety. Accurate color measurements are essential for compliance with quality standards and to prevent any risk associated with incorrect data interpretation that could affect product quality and safety.

2. Scope

• Asset ID: CAL-0233
• Equipment Name/Type: Colorimeter
• Department/Area: QC, Chemistry Lab
• Process Use: Color
• Parameter: Color
• Range: 0 to 5 Abs
• Units: Abs
• 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 the calibration is still valid.
• Adjustment: The act of modifying the 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 exceeds the acceptance criteria.
• Drift: The gradual change in the instrument’s performance 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 is asserted to lie.
• Intermediate Check: A periodic check performed to ensure the instrument remains within specified limits 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 maintained.
• External Service Provider: Conduct external calibration as per schedule.

6. Safety & Preconditions

• Ensure environmental controls are in place (temperature, humidity).
• Allow for warm-up/stabilization period 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: Ensure all certificates are current and valid.
• Standard ID Placeholders: [TBD]

8. Calibration Strategy

The calibration will follow an As Found and As Left logic. The minimum number of test points will be five, including the endpoints (0 and 5 Abs) and midpoints. 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 Colorimeter to warm up for the specified time.
3. As Found Checks and Data Capture: Record initial readings at each test point.
4. Adjustment Rules: If any readings are OOT, follow adjustment protocols; if adjustments are not allowed, escalate to QA.
5. As Left Verification: Record final readings after adjustments.
6. Labeling + Documentation Completion: Ensure all records are completed and raw observations are documented contemporaneously (ALCOA+).

10. Acceptance Criteria & Calculations

The acceptance criteria for the Colorimeter calibration is ±2%. The error calculation formula is:

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

Pass/Fail Logic: If the error falls within ±2%, the calibration is considered a pass; otherwise, it is a fail.

Rounding Rule: [TBD]

11. Handling OOT / Failures

• Immediate containment: Tag the equipment and cease use.
• Notification & deviation initiation: Notify QA and document the deviation.
• 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: 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.
