Calibration SOP

1. Purpose

The calibration of the Stopwatch (Asset ID: CAL-0262) is performed to ensure accurate timing measurements, which are critical for maintaining batch quality and ensuring compliance with quality control processes. Accurate timing is essential to prevent deviations that could impact product quality and patient safety.

2. Scope

  • Asset ID: CAL-0262
  • Equipment Name/Type: Stopwatch
  • Department/Area: QC / General
  • Process Use: Timing
  • Parameter: Time
  • Range: 0 – 3600 seconds
  • Units: sec
  • 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 specifications.
  • As Found: The state of the instrument prior to any adjustments.
  • As Left: The state of the instrument after adjustments have been made.
  • OOT (Out of Tolerance): A condition where the measurement results exceed specified acceptance criteria.
  • Drift: The gradual change in the output of a measurement instrument over time.
  • Traceability: The ability to relate individual measurement results 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 verification process conducted between scheduled calibrations to ensure continued accuracy.

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 accessible for calibration.
  • External Service Provider: Conduct external calibration as per the calibration type.

6. Safety & Preconditions

  • Ensure the calibration area is clean and free from contaminants.
  • Verify that the Stopwatch is properly leveled.
  • Check the power supply to ensure it is stable and within specifications.
  • Allow the Stopwatch to warm up and stabilize before calibration.

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 the As Found and As Left logic:

  • Minimum number of points: At least 5 points including endpoints (0 sec, 1800 sec, 3600 sec) and midpoints.
  • Replicate readings: 3 repeats at each point for accuracy.

9. Step-by-Step Procedure

  1. Preparation: Gather all necessary tools and reference standards.
  2. Stabilization: Allow the Stopwatch to stabilize in the calibration environment.
  3. As Found checks and data capture: Record initial measurements at defined points.
  4. Adjustment rules: If OOT is detected, follow escalation procedures; adjustments are only made if allowed.
  5. As Left verification: Confirm that the Stopwatch is within acceptance criteria after adjustments.
  6. Labeling + documentation completion: Complete all required documentation and label the equipment appropriately.

Record raw observations contemporaneously to ensure data integrity (ALCOA+).

10. Acceptance Criteria & Calculations

Acceptance criteria: ±1 sec

Error calculation formula: Error = Observed Value – True Value

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

Rounding rule placeholder: [TBD]

11. Handling OOT / Failures

  • Immediate containment: Tag equipment and stop use.
  • Notification & deviation initiation: Notify relevant personnel of the OOT condition.
  • Impact assessment trigger: Define impact window and review of 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.
  • Calibration report/certificate filing: Maintain records in accordance with company policy.
  • e-records if applicable: [TBD]
  • Label content requirements: calibrated date, due date, by whom, status.

Stepwise Instructions

  1. Preparation: Ensure the stopwatch is clean and functioning. Verify the calibration equipment is available and operational.
  2. Stabilization: Allow the stopwatch to acclimate to the environmental conditions for at least 30 minutes.
  3. Performing Readings:
    • At each test point, activate the stopwatch and record the time.
    • Take three replicate readings at each point and calculate the average.
  4. Calculating Error: Determine the error by subtracting the reference value from the observed value.
  5. Evaluation: Compare the calculated error against the acceptance criteria of ±1 sec.
  6. Documentation: Complete the results table with all observed values and errors.

Deviation Instruction for OOT

If any observed value falls outside the acceptance criteria:

  • Stop use of the stopwatch immediately.
  • Notify the supervisor and quality assurance.
  • Open a deviation report.
  • Quarantine impacted results window: [TBD]
  • Await QA decision on further actions.
