2.14 Environmental protection
Seagate designs its products to meet environmental protection requirements worldwide, including regulations restricting certain 
chemical substances.
2.14.1
European Union Restriction of Hazardous Substances (RoHS) Directive
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.
2.14.2
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 homogeneous 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 homogeneous material level) is over the threshold 
defined by the China RoHS MCV Standard. 
2.15 Corrosive 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.
