Test Plan
| Test ID | Procedure | Acceptance Criteria | Evidence |
|---|---|---|---|
| T1 | Verify accuracy using standard reference materials. | Results must fall within ±5% of the known values. | Calibration report and test results. |
| T2 | Assess repeatability by performing multiple measurements. | Standard deviation must be less than 2% of the mean. | Statistical analysis report. |
| T3 | Check audit trail functionality. | All actions must be logged with user ID and timestamp. | Audit trail report from the software. |
Detailed Test Cases
Test Case T1: Accuracy Verification
Procedure: Use standard reference materials with known particle sizes to verify the accuracy of the analyzer.
Acceptance Criteria: Results must fall within ±5% of the known values.
Evidence: Calibration report and test results must be documented.
Test Case T2: Repeatability Assessment
Procedure: Conduct a series of measurements on the same sample to evaluate repeatability.
Acceptance Criteria: Standard deviation must be less than 2% of the mean.
Evidence: Statistical analysis report must be generated and reviewed.
Test Case T3: Audit Trail Check
Procedure: Review the audit trail functionality of the software.
Acceptance Criteria: All actions must be logged with user ID and timestamp.
Evidence: Audit trail report must be generated for review.
Deviations
Any deviations from this protocol must be documented and justified. A deviation report must be submitted to the Quality Assurance team for review and approval.
