OEKO-TEX® STANDARD 100

If a textile article carries the OEKO-TEX® STANDARD 100 label, you can be certain that the article therefore is harmless for human health. In many cases the limit values for the STANDARD 100 go beyond national and international requirements. The criteria catalog is updated at least once a year and expanded with new scientific knowledge or statutory requirements. ZHYO070054  OEKO-TEX® Label Check.

Grounding

This product with an electrically isolated surface cannot be contacted or grounded.

Shielding attenuation HF & LF

This product shields high frequency electromagnetic fields (HF). Unless otherwise stated, the indicated dB-values apply to 1 GHz. Measurement from 600 MHz to 40 GHz according to standards ASTM D4935-10 or IEEE Std 299-2006.

This product contains electrically conductive parts on the inside which can neither be contacted nor grounded. That’s why individual areas do not shield low frequency electrical fields (LF). In case this product is used as a Faraday cage (complete shielding on six sides), there will be no low frequency electrical fields (LF) on the inside, which can be proven with a potential free measurement.
