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.

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.
