Effective July 1st, 2006, European Union has required electronic products entering
the European Union market to be free of six specific hazardous substances,
(lead,mercury,chromium VI) and the fire retardants (PBB & PBDE). Together these
regulations are referred to as the "Restriction of Hazardous Substances" or "RoHS
directive". The intended results of this legislation is to reduce the amount of these
substances that are eventually returned to the environment when electronic
products are discarded.
