Restriction on Hazardous Substances (RoHS) Directive
Directive 2002/95/EC—commonly known as the European Union (EU)
Restriction on Hazardous Substances (RoHS)—sets limits on the use of
certain substances found in electrical and electronic equipment. The
intent of this legislation is to reduce the amount of hazardous chemicals
that may leach out of landfill sites or otherwise contaminate the
environment during end-of-life recycling. The Directive, which took
effect on July 1, 2006, refers to the following hazardous substances:
• Lead (Pb)
• Mercury (Hg)
• Cadmium (Cd)
• Hexavalent Chromium (Cr-V1)
• Polybrominated Biphenyls (PBB)
• Polybrominated Diphenyl Ethers (PBDE)
According to this EU Directive, all products sold in the European Union
will be fully RoHS-compliant and “lead-free.” (See our website for
more information on dates and deadlines for compliance.) Spare parts
supplied for the repair and upgrade of equipment sold before
July 1, 2006 are exempt from the legislation. Equipment that complies
with the EU directive will be marked with a RoHS-compliant emblem,
as shown in Figure P-1.

Preface
Waste from Electrical and Electronic Equipment
(WEEE) Directive
The European Union (EU) Directive 2002/96/EC on Waste from
Electrical and Electronic Equipment (WEEE) deals with the collection,
treatment, recovery, and recycling of electrical and electronic waste
products. The objective of the WEEE Directive is to assign the
responsibility for the disposal of associated hazardous waste to either
the producers or users of these products. As of August 13, 2005,
producers or users are required to recycle electrical and electronic
equipment at end of its useful life, and may not dispose of the
equipment in landfills or by using other unapproved methods. (Some
EU member states may have different deadlines.)
In accordance with this EU Directive, companies selling electric or
electronic devices in the EU will affix labels indicating that such prod-
ucts must be properly recycled. (See our website for more information
on dates and deadlines for compliance.) Contact your local sales repre-
sentative for information on returning these products for recycling.
Equipment that complies with the EU directive will be marked with a
WEEE-compliant emblem, as shown in Figure P-2.
