SLVR® Scrubs - SLVR777™ fabric (report DZ2025A082)
The SLVR777™ fabric used in SLVR® Scrubs was tested by a CNAS-accredited (ISO/IEC 17025) laboratory, Beijing Daze Technology (report DZ2025A082, October 2025). Result: 30.7 dB (99.91%) signal attenuation at 50 GHz through a single layer of fabric, and 35.2 dB (99.97%) or more at every test point from 30 MHz to 40 GHz. Results are for the fabric sample tested. Whole-garment performance is lower at openings and seams. Designed to reduce RF signal exposure. Not a medical device.
15 frequencies (16 measurements) from 9 kHz to 50 GHz
Measured using GJB 5792A-2021, a Chinese military-standard (GJB) shielding measurement method.
