Objective
The objective of this Operational Qualification (OQ) protocol is to verify that the Drying Oven for Coated Devices operates within specified parameters to ensure effective curing and drying of coatings applied to drug-eluting stents.
Scope
This protocol applies to the Drying Oven used in the R&D/Production area for the curing and drying of coatings on drug-eluting stents and coated devices.
Responsibilities
The Validation Team is responsible for executing this protocol, documenting results, and reporting findings. The Quality Assurance Team is responsible for reviewing and approving the protocol and results.
Prerequisites
1. Installation Qualification (IQ) must be completed and approved.
2. Staff must be trained on the operation of the Drying Oven.
Equipment Description
The Drying Oven is designed to cure and dry coatings applied to drug-eluting stents. It features adjustable temperature settings, airflow controls, and monitoring capabilities to ensure uniform drying conditions.
Test Plan
| Test ID | Procedure | Acceptance Criteria | Evidence |
|---|---|---|---|
| OQ-DO-01 | Temperature Uniformity Test | Temperature variation within ±2°C | Temperature logs |
| OQ-DO-02 | Time and Airflow Validation | Airflow records meet specifications | Airflow logs |
Detailed Test Cases
Test ID: OQ-DO-01
Procedure: Measure temperature at multiple points within the oven during operation.
Acceptance Criteria: Temperature variation must be within ±2°C.
Evidence: Documented temperature logs for each test point.
Test ID: OQ-DO-02
Procedure: Verify airflow settings and record airflow rates during operation.
Acceptance Criteria: Airflow records must meet pre-defined specifications.
Evidence: Documented airflow logs.
Deviations
Any deviations from the acceptance criteria must be documented and reviewed. A root cause analysis will be conducted for any critical deviations.
