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 DH55HC complies with these restrictions.
