FAQ
1. What is the purpose of the Garment Electromagnetic Radiation Shielding Performance Testing System?
This system is designed to evaluate the effectiveness of protective clothing against electromagnetic radiation. Using a microwave test manikin in a semi-anechoic chamber, it measures the attenuation of electromagnetic waves on the head, chest, and abdomen of garments. By simulating real-life exposure conditions, it provides accurate, reproducible data to assess the protective performance of finished garments and raw materials. This enables manufacturers and R&D teams to verify that clothing meets international safety standards and protects users from EMF exposure.
2. How does the system measure shielding effectiveness?
The system uses a microwave test manikin embedded with EMF receiving sensors placed in a semi-anechoic chamber. A signal amplifier with a directional transmitting antenna emits electromagnetic waves, while the manikin sensors record real-time attenuation at multiple points, including the head, chest, and abdomen. A high-precision Vector Network Analyzer (VNA) processes these measurements to quantify the shielding effectiveness across the target frequency range of 80 MHz to 1 GHz. Integrated software collects and analyzes the data, producing performance curves and automated reports.
