Restriction of Hazardous Substances (RoHS)
EU RoHS
EU RoHS Directive 2002/95/EC restricts the use of the following six materials in
various types of electronic and electrical equipment:
• Lead
• Mercury
• Cadmium
• Hexavalent chromium
• Polybrominated biphenyls (PBB)
• Polybrominated diphenyl ether (PBDE)
The maximum concentrations allowed are 0.1% or 1000 ppm (except for cadmium,
which is limited to 0.01% or 100 ppm) by weight of homogeneous material.
Intel Desktop Board DP55WG complies with these restrictions.
