Supply Chain Control: The “Article 10” Obligation
The Nightmare Scenario: Unannounced Audits
Explain that Notified Bodies (like Intertek Semko) now perform unannounced factory checks. A “Silent Change” in the PSU components can revoke the device’s certificate.
Regulatory oversight in the EU has intensified. Notified Bodies, such as Intertek Semko, now conduct unannounced audits at manufacturing sites. These audits target electrical medical devices and scrutinize every aspect of production, especially the power supply. Silent changes—unannounced modifications to components like capacitors—pose the greatest threat to MDR compliance. Even a minor alteration can disrupt the electromagnetic compatibility profile, leading to failures in IEC 60601 testing. Notified Bodies demand traceable documentation for all components. If a silent change occurs, the original EMC test reports and the Technical File become invalid. This invalidation can result in certification delays, product recalls, or removal from the healthcare market.
Manufacturers must establish robust controls to prevent such risks. Article 10 of MDR outlines clear requirements for supply chain management. The table below summarizes these obligations:
Obligation | 説明 |
|---|---|
Quality Management System | Manufacturers must establish a robust QMS to ensure compliance with regulatory standards. |
サプライヤー管理 | Manufacturers are required to implement adequate controls and monitoring of suppliers to ensure compliance with IVDR. |
リスク管理 | Manufacturers must conduct risk management and performance monitoring of suppliers based on associated risks. |
Silent changes undermine electrical safety and compromise the safety and efficacy of medical electrical equipment. They also threaten compliance with IEC 60601 safety standards. Manufacturers must treat every component as critical to device certification.
