NVIRONMENTAL PROTECTION
Seagate designs its products to meet environmental protection requirements worldwide, including regulations restricting certain chemical
substances.
2.15.1

European Union Restriction of Hazardous Substances (RoHS) Directive

Seagate designs its products to meet environmental protection requirements worldwide, including regulations restricting certain chemical
substances. A new law, the European Union Restriction of Hazardous Substances (RoHS) Directive, restricts the presence of chemical
substances, including Lead, Cadmium, Mercury, Hexavalent Chromium, PBB and PBDE, in electronic products, effective July 2006. This
drive is manufactured with components and materials that comply with the RoHS Directive.
2.15.2

China Restriction of Hazardous Substances (RoHS) Directive

This product has an Environmental Protection Use Period (EPUP) of 20 years. The following table contains information
mandated by China's "Marking Requirements for Control of Pollution Caused by Electronic Information Products" Standard.
"O" indicates the hazardous and toxic substance content of the part (at the homogenous material level) is lower than the threshold defined
by the China RoHS MCV Standard.
"X" indicates the hazardous and toxic substance content of the part (at the homogenous material level) is over the threshold defined by the
China RoHS MCV Standard.

ORROSIVE ENVIRONMENT
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial environments
containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this accelerated testing cannot duplicate
every potential application environment. Users should use caution exposing any electronic components to uncontrolled chemical pollutants
and corrosive chemicals as electronic drive component reliability can be affected by the installation environment. The silver, copper, nickel
and gold films used in Seagate products are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is
found to be the most damaging. In addition, electronic components should never be exposed to condensing water on the surface of the
printed circuit board assembly (PCBA) or exposed to an ambient relative humidity greater than 95%. Materials used in cabinet fabrication,
such as vulcanized rubber, that can outgas corrosive compounds should be minimized or eliminated. The useful life of any electronic
equipment may be extended by replacing materials near circuitry with sulfide-free alternatives.
