About the S200S RF EMF/EMR Blocking Fabric

The S200S is a China made, DOUBLE LAYER KNITTER RF Blocking fabric.  The S200S fabric has the composition of cotton, polyester and silver yarn.
 It is a 
DOUBLE LAYER KNITTED 200 g fabric. One side/layer (the Gray side) includes silver yarn. The other side/layer(CcamouflageGray has no steel in it.  

RF Blocking effect - Fabric's RF blocking effect = 30-40dB according to manufacture data sheet (10MHz-300MHz). But I find the report to be inadequate for presentation, so we 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 ~99%/-20dB (using CORNET ED88T in front of a DECT Phone 1.8GHz. In most of the tests we have seen even better outcomes).
The fabric was then tested again and showed good results even after more than 6 laundry cycles in a washing machine in  40-60 degrees cycles, with soap.
Please see test outcomes at the bottom of this page. 
The fabric does not block ELF magnetic fields from electric cabinets/equipment and power lines).

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