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 corro-

sive chemicals as electronic drive component reliability can be affected by the installation environment. The sil-

ver, 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 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.
