About the S190 RF EMF/EMR Blocking Fabric

The S190 is a China made RF Blocking fabric.  The S190 fabric has the composition of cotton, polyester and Stainless Steel metal fibers.  It is a DOUBLE LAYER WOVEN  190 g fabric. One side/layer (the Gray side) includes stainless steel fibers. The other side/layer has no steel in it.  

RF Blocking effect - Fabric's RF blocking effect = 27-37dB according to manufacture data sheet. (Frequencies of 1GHz to 10GHz). But I find the report to be inadequate for presentation, so I tested the fabric myself. 
The fabric was tested by us and showed good RF Blocking effect.
Our tests showed that the RF blocking effect was at least ~96%/-14dB (using CORNET ED88T in front of a DECT Phone 1.8GHz. In most test we have seen even better outcomes).
The fabric does not block ELF magnetic fields from electric cabinets/equipment and power lines).
The fabric was tested again and again and showed good results even after more than 15 londry cycles in a washing machine in 40 degrees cycles, with soap.

The Fabric is durable and it ability to block RF is not reduced over laundry cycles.
