Magicleaf provides third-party shielding test data for qualified buyers who need product verification during sourcing and procurement. Magicleaf's shielding-related products use conductive lining material that has been tested by the Shanghai Institute of Measurement and Testing Technology (SIMT), an accredited third-party laboratory under China's national metrology system.
The test results show shielding effectiveness across a wide frequency range, from 12 MHz to 3000 MHz. The reported attenuation depth ranges from 70.7 dB to 74.2 dB, with shielding effectiveness reaching 99.9999% or higher at every tested frequency band. These results help buyers better understand how the material performs against RFID, GPS, cellular signals, and WiFi frequency ranges covered by the report.
