Grounding:
Cannot be contacted and therefore cannot be grounded. Low-frequency electrical fields (LF) must be reduced by additional procedures. We recommend to shield these fields or to switch them off with a demand switch.
Shielding attenuation:
All shielding attenuation values are valid at 1GHz. Measurement according to ASTM D4935-10 /IEEE Std 299-2006 / IEEEE Std 1128-1998 / ASTM A698/A698M-07.
Care
Cleaning in a washing machine at 30°C is possible. No handwashing!
For allergic persons: Every new fabric smells! Always wash before its first usage!
Please note: The price is valid per m² (square metre), not per running metre!
Starting from the web width, the product can be ordered in measures of 0.1 running metres.
This product is cut off a large roll according to customer specifications. A return is not possible!
RF Shielding Fabric "Swiss Shield Naturell"
- for shielding widely against RF high frequency electromagnetic waves
- decorative half transparent cotton fabric with spon- in silvered copper filaments
- 100% textile character: washable, easy to manufacture and to iron
- ideal curtain material with typical textile characteristics of cotton
This material is preferably used as curtain material in front of windows, for partial shielding of walls or as bed canopy. It is soft, light, transparent and ist easy to sew, respectively to manufacture. Swiss Shield Naturell shields particularly well high frequency electromagnetic waves (by reflection). The shielding attenuation is independent from the direction of th incoming signals.
In order to avoid slits in the RF shield, oberlapping seams should be made on sewing.
Swiss Shield Naturell needs not and cannot be grounded.
Please note:
RF shielding measures without groundings presume that the electrical AC fields existing in the concerned room are reduced to a minimum by switching off voltage or by shieldings. If this is not done before, the non- grounded RF shielding areas, even those which cannot be grounded can couple to electrical AC fields and can intensify their effects.
