6.5.5
Air cleanliness
The drive is designed to operate in a typical office environment with minimal environmental control.
6.5.6
Corrosive environment
Seagate electronic drive components pass accelerated corrosion testi ng equivalent to 10 years exposure to light industrial envi ronments
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 elec tronic
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 relati ve 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.
6.5.7
Acoustics
Sound power during idle mode shall be 3.25 bels typical when measured to ISO 7779 specification.
Sound power during operating mode shall be 3.35 bels typical when measured to ISO 7779 specification.
There will not be any discrete tones more than 9 dB above the masking noise on typical drives when measured according to Seagate
specification 30553-001. There will not be any tones more than 24 dB above the masking noise on any drive.
