MDR Compliance Tests of Medical Devices

The European Union's Medical Device Regulation (MDR) (EU) 2017/745 is a comprehensive regulation that determines the safety, effectiveness and quality standards of medical devices. This regulation requires rigorous evaluation and conformity testing in the design, production and marketing of medical devices. MDR requires that all medical devices be classified according to their risk level and undergo appropriate testing processes. EUROLAB As a laboratory, we offer comprehensive testing services to ensure medical devices comply with MDR.

Device Classification and Conformity Assessment

MDR divides medical devices into four main classes according to their risks: I, IIa, IIb and III. This classification is made depending on the level of invasiveness of the devices, duration of use and contact with the human body. Different conformity assessment procedures are required for each class.

1. Class: Low-risk devices (for example, elastic bandages).
2. Class IIa: Moderate risk devices (for example, dental filling materials).
3. Class IIb: High-risk devices (for example, X-ray machines).
4. Class III: Highest risk devices (for example, pacemakers).

Biocompatibility Tests

Biocompatibility testing of medical devices determines whether the devices are safe when in contact with the human body. These tests are especially important for long-term implants or devices that come into contact with body fluids.

Test Scope

• Cytotoxicity: Toxic effect of the device material on cells.
• Sensibilization: Potential for allergic reactions.
• Irritation: Risk of irritation to skin, eyes or mucosal surfaces.
• Chronic Toxicity: Health effects of long-term exposure.

Applied Standards

• ISO 10993-1: Biological evaluation.
• ISO 10993-5: Cytotoxicity tests.
• ISO 10993-10: Irritation and sensibilization tests.

Electrical Safety and Electromagnetic Compatibility (EMC) Tests

Electrical safety and electromagnetic compatibility tests are required for electrical medical devices to operate safely and be compatible with other electronic devices.

Test Scope

• Electrical Safety: Leakage current, insulation and grounding test.
• EMC: Electromagnetic emission and immunity tests.
• Functional Safety: Whether the device performs the specified functions safely.

Applied Standards

• IEC 60601-1: Safety of medical electrical devices.
• IEC 60601-1-2: Electromagnetic compatibility.
• IEC 62304: Life cycle processes of medical device software.

Sterilization and Microbiological Cleaning Tests

Sterilization and microbiological cleaning tests are essential for the safe use of sterile medical devices in the hospital environment.

Test Scope

• Biological Burden: Number of microorganisms found on the device.
• Sterility Test: Verification of sterilization effectiveness.
• Endotoxin Test: Devices are free of bacterial toxins.

Applied Standards

• ISO 11737-1: Bioburden testing of sterilization.
• ISO 14698: Biological contamination control.
• ISO 11137: Sterilization by radiation.

Mechanical and Physical Endurance Tests

Mechanical and physical durability tests determine whether medical devices can withstand physical damage during use.

Test Scope

• Impact Resistance: Durability of devices against falling or impact.
• Tensile and Pressure: Durability under mechanical loads.
• Wear and Tear: Durability of devices in long-term use.

Applied Standards

• ISO 10555: Mechanical durability of single-use sterile medical devices.
• ISO 14630: General requirements and test methods.
• ISO 7198: Mechanical properties for vascular devices.

Software Validation and Kiber Security

Medical device software is an important component, especially in devices that perform critical functions. Software validation and kiber security tests ensure safe and error-free operation of device software.

Test Scope

• Software Validation: Verification of software compliance with specified requirements.
• Cyber ​​security: Protection of software against cyber threats.
• User Interface Testing: Security and user-friendliness of the user interface.

Applied Standards

• IEC 62304: Medical device software - Lifecycle processes.
• ISO/IEC 27001: Information security management systems.
• FDA 21 CFR Part 11: Electronic records and signatures.

Clinical Evaluation and Performance Tests

Clinical evaluation and performance testing evaluates the effectiveness and safety of medical devices in clinical settings.

Test Scope

• Clinical Evaluation: Evaluation of the clinical benefits and risks of the device.
• Performance Tests: Whether the device performs the specified clinical functions.
• Risk management: Assessment and management of potential clinical risks.

Applied Standards

• ISO 14155: Conducting clinical research.
• ISO 14971: Risk management in medical devices.
• MEDDEV 2.7/1: Clinical assessment guide.
