Corrosive environment

Maxtor 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 Maxtor 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.
