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)
The European Union Restriction of Hazardous Substance s (R oHS ) Dire ctive re stri ct s the p resen ce of ch emical
substances, including Lead (Pb), in electronic products effective July 2006.
A number of parts and materials in Seagate products are procured from external suppliers. We rely on the
rep-resentations of our suppliers regarding the pr esence of R oHS substanc es in these parts and mate rials. Our
supplier contracts require compliance with our chemical substance restrictions, and our suppliers document
their compliance with our requirements by providing material conte nt declar ations for al l par ts an d mater ial s for
the disc drives documented in this publication. Current supplier declarations include disclosure of the inclusion
of any RoHS-regulated substance in such parts or materials.
Seagate also has internal systems in place to ensure ongoing compliance with the RoHS Directive and all laws
and regulations which restrict chemical content in electronic products. These systems include standard
operat-ing procedures that ensure that restricted substances are not utilized in our manufacturing operations,
labora-tory analytical validation testing, and an internal auditing process to ensure that all standard operating
procedures are complied with.
2.16 Co rrosive environmen tSeagate 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 product s are especiall y sen siti ve to the p resen ce of sulfide, chlo-
ride, 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 th an 9 5%. Materials used in cabinet fabrication, such as vulca-
nized 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.
