Measured results of shielding effectiveness
The shielding material SR-Shield RS1 presents an extreme high shielding effectiveness to linear polarized electromagnetic waves and circular polarized waves. Following table presents a quick overview of the shielding effectiveness at different frequencies in the UHF- and SHF-range.
| Communication service | SR-Shield RS1 |
| C-Netz, TETRA, 450 MHz | 71 dB |
| D-Netz, 900 MHz | 70 dB |
| E-Netz, 1800 MHz | 68 dB |
| Blue-Tooth, 2450 MHz | 67 dB |
| 4 GHz | 67 dB |

Measured results of specific resistance and conductivity of the surface
The results found during the measurements of the SR-Shielding RS1 depended on the thickness of the fabric, the thickness of the threads used and the thickness of the metallic coating of the material.
The following results were measured:
| SR-Shield RS1 | |
| Specific Surface Resistance | 51 - 62 mΩ |
| Specific Surface Conductivity | 16 - 19 S |
* Measurements accomplished in 2008 by Prof. Dipl.-Ing. P. Pauli, German Armed Forces University Munich for RF-, Microwaves and Radar in Neubiberg.
