Garment Electromagnetic Radiation Shielding Performance Testing System

About 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.

Application

The system is suitable for a wide range of applications:

Assessing electromagnetic shielding performance of protective clothing in research and development

Evaluating finished garments and critical raw materials for EMF protection

Supporting quality control in textile and wearable electronics industries

Verifying compliance of protective apparel used in industrial, medical, or military environments

Test Procedures

Sample Preparation

Include finished garments and critical raw materials to evaluate both overall and component-level shielding.

Ensure garments are properly mounted on the manikin with sensors correctly positioned.

Environmental Control

Conduct testing in a low-noise, semi-anechoic chamber to minimize external electromagnetic interference.

Measurement

Activate the electromagnetic radiation source and record real-time attenuation at head, chest, and abdomen using the manikin sensors.

Use the Vector Network Analyzer to measure shielding effectiveness across the target frequency range.

Durability Assessment

Optionally perform wash, friction, and other stress tests on the garment before re-evaluating shielding performance.

Data Recording

Analyze and record results with integrated software, generating performance curves and standardized reports.

Maintenance Information

Regularly inspect and calibrate the vector network analyzer and sensors to ensure accuracy

Maintain semi-anechoic chamber cleanliness and check shielding integrity periodically

Verify signal amplifier and antenna operation before each test

Ensure environmental sensors are functional and provide accurate temperature and humidity readings

Store manikin and sensitive components properly when not in use to prevent mechanical or electrical damage
