Technical standards


Our final products are produced in Europe and conform to all European and FCC standards.

EC guideline (RoHS)

The EC "Restriction of Hazardous Substances in Electrical & Electronic Equipment" (RoHS) guideline has been released in order to reduce the heavy metal load in electrical and electronic products caused by e.g. lead and mercury. All manufacturers are obligated to provide only RoHS-compliant products to the European market, effective from July 1st, 2006.

In cooperation with our suppliers, all relevant products are currently redesigned to comply with the EC guideline. Thus, HW group s.r.o will be able to deliver some RoHS-compliant products already before the guideline's official commencement of July 1st, 2006 (probably April 2006).
