III. Medical Environment Suitability
1. Electromagnetic Compatibility (EMC) Verification
This model has undergone electromagnetic disturbance testing within a complete medical device system:
- Standard：EN 55032 Class B (Radiated Emission)
- Test Condition：AC 230V / 50Hz
- Result：Complies with Class B limits, demonstrating good EMC performance
Key Data Example (Conducted Emission – L Phase)：
| Frequency(MHz) | Measurement(dBuV) | Limit(dBuV) | Margin(dB) |
|---|---|---|---|
| 0.4425 | 43.79 (QP) | 57.01 | -13.22 |
| 0.5505 | 42.21 (QP) | 56.00 | -13.79 |
Note: The radiated emission test graph shows no obvious violations in the 30MHz~1GHz range, meeting medical device radiated emission limits.
2. Electrostatic Discharge (ESD) Protection
This display has passed 15kV ~ 20kV air discharge testing within the medical device system, offering the following advantages：
- Suitable for high-static-risk environments (dry conditions, frequent operator contact)
- No flickering, black screen, or display abnormalities during ESD events
- Touch functionality (if applicable) remains unaffected
3. Environmental and Safety Compliance
✅ ROHS (Restriction of Hazardous Substances) ✅ REACH (Registration, Evaluation, Authorization and Restriction of Chemicals)
Material selection meets basic requirements for biocompatibility and low outgassing in medical devices
IV. Recommended Applications
