2 Statement on Environmental Protection
2.1 Compliance to RoHS Directive
Directive 2002/95/EC of the European Commission on the "Restriction of the use of
certain Hazardous Substances in Electrical and Electronic Equipment" (RoHS)
predicts that all electrical and electronic equipment being put on the European market
after June 30th, 2006 must contain lead, mercury, hexavalent chromium,
polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE) and
cadmium in maximum concentration values of 0.1% respective 0.01% by weight in
homogenous materials only.
As these hazardous substances are currently used with semiconductors, plastics (i.e.
semiconductor packages, connectors) and soldering tin any hardware product is
affected by the RoHS directive if it does not belong to one of the groups of products
exempted from the RoHS directive.
Although many of hardware products of N.A.T. are exempted from the RoHS
directive it is a declared policy of N.A.T. to provide all products fully compliant to the
RoHS directive as soon as possible. For this purpose since January 31st, 2005 N.A.T.
is requesting RoHS compliant deliveries from its suppliers. Special attention and care
has been paid to the production cycle, so that wherever and whenever possible RoHS
components are used with N.A.T. hardware products already.
2.2 Compliance to WEEE Directive
Directive 2002/95/EC of the European Commission on "Waste Electrical and
Electronic Equipment" (WEEE) predicts that every manufacturer of electrical and
electronical equipment which is put on the European market has to contribute to the
reuse, recycling and other forms of recovery of such waste so as to reduce disposal.
Moreover this directive refers to the Directive 2002/95/EC of the European
Commission on the "Restriction of the use of certain Hazardous Substances in
Electrical and Electronic Equipment" (RoHS).
Having its main focus on private persons and households using such electrical and
electronic equipment the directive also affects business-to-business relationships. The
directive is quite restrictive on how such waste of private persons and households has
to be handled by the supplier/manufacturer, however, it allows a greater flexibility in
business-to-business relationships. This pays tribute to the fact with industrial use
electrical and electronical products are commonly integrated into larger and more
complex environments or systems that cannot easily be split up again when it comes to
their disposal at the end of their life cycles.
