01. Cloth Combustion Method
Note: This method is only applicable to the testing of metal fiber anti electromagnetic radiation fabrics
Take out the small sample cloth from the clothing tag, burn it thoroughly with fire, and after that, you can see a fine mesh residue, which is the metal fiber mesh. It is used to prevent electromagnetic radiation.
02. Conductive Method
Resistance testing method
The essential difference between anti electromagnetic radiation fabric and ordinary fabric is that anti electromagnetic radiation fabric is conductive while ordinary fabric is non-conductive. Therefore, using a multimeter to test the resistance of the fabric can determine whether it is effective. If you don't have a multimeter at home, you can take the fabric to the home appliance repair department for the technician to inspect.
Detection pen test
This test pen can provide a simple and intuitive qualitative test of the effectiveness of anti electromagnetic radiation products. Remove the pen holder and touch the detection pen head onto the shielding cloth. The indicator light will light up, indicating that the shielding cloth can conduct electricity and has a protective effect against electromagnetic radiation.
