Garment Electromagnetic Radiation Shielding Performance Testing System
The Garment Electromagnetic Radiation Shielding Performance Testing System is a comprehensive testing solution designed to evaluate the shielding effectiveness of protective clothing against electromagnetic radiation. Using a microwave test manikin in a controlled semi-anechoic chamber, the system measures the attenuation of electromagnetic waves on the head, chest, and abdomen of a dressed manikin. By simulating real-life conditions, the system provides accurate, reproducible assessment of garments’ protective performance across different frequencies.
Standards
The testing system supports compliance with the following standards:
GB 23463-2025 – Protective Clothing for Microwave Radiation
GB/T 33615-2017 – Methods for Testing Electromagnetic Shielding Performance of Garments
DIN 32780-100 – Protective Clothing, Part 100: Electromagnetic Field Protection in 80 MHz–1 GHz Range
IEC 61000-4-3 – Testing and Measurement Techniques for Radiated RF Electromagnetic Fields
ISO 105-X12 – Textiles: Color Fastness to Electromagnetic Effects (Reference for material durability)
