Acoustics; Air Cleanliness; Corrosive Environment; Electromagnetic Susceptibility - Seagate Constellation ES Product Manual

c. Non-operating
The limits of non-operating vibration shall apply to all conditions of handling and transportation. This
includes both isolated drives and integrated drives.
The drive shall not incur physical damage or degraded performance as a result of continuous vibration not
exceeding
5 - 22 Hz
22 - 350 Hz
350 - 500 Hz
Vibration may be applied in the X, Y, or Z axis.
7.5.5

Acoustics

Sound power during idle mode shall be 2.7 bels typical when measured to ISO 7779 specification. Sound
power while operating shall be 3.0 bels typical when measured to ISO 7779 specification.
There will not be any discrete tones more than 10 dB above the masking noise on typical drives when mea-
sured according to Seagate specification 30553-001. There will not be any tones more than 24 dB above the
masking noise on any drive.
7.5.6

Air cleanliness

The drive is designed to operate in a typical office environment with minimal environmental control.
7.5.7

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.
