Test Plan
| Test ID | Procedure | Acceptance Criteria | Evidence |
|---|---|---|---|
| DQ-01 | Pressure Passes Test | Pressure levels within specified limits | Test log and calibration records |
| DQ-02 | Temperature Monitoring | Temperature remains within acceptable range | Temperature logs |
| DQ-03 | Flow Rate Audit | Flow rate meets specified standards | Flow rate measurements |
| DQ-04 | Audit Trail Review | Complete and accurate audit trail | Audit trail documentation |
Detailed Test Cases
Test Case: DQ-01 – Pressure Passes Test
Procedure: Operate the homogenizer at specified pressure settings for a minimum of 30 minutes. Record pressure levels at regular intervals.
Acceptance Criteria: Pressure levels must remain within the specified limits throughout the test duration.
Evidence: Pressure logs will be reviewed for compliance.
Test Case: DQ-02 – Temperature Monitoring
Procedure: Monitor the temperature of the homogenizer during operation. Record readings every 10 minutes.
Acceptance Criteria: The temperature must not exceed the defined upper limit.
Evidence: Collected temperature logs will be evaluated.
Test Case: DQ-03 – Flow Rate Audit
Procedure: Measure the flow rate of the product during processing and document the results.
Acceptance Criteria: Flow rate must meet the established specifications.
Evidence: Flow rate measurements will be compiled for review.
Test Case: DQ-04 – Audit Trail Review
Procedure: Review the audit trail generated during the operation of the homogenizer for completeness and accuracy.
Acceptance Criteria: The audit trail must be complete without any discrepancies.
Evidence: Audit trail documentation will be assessed for compliance.
Deviations
Any deviations from the acceptance criteria must be documented and reported to the Validation Team for further investigation and resolution.
Approvals
This protocol must be reviewed and approved by the designated personnel before execution.
