7.5.4.2 Vibration
a. Operating—normal
The drive as installed for normal operation, shall comply with the complete specified performance while
subjected to vibration:
Vibration may be applied in the X, Y, or Z axis.
Operating normal translational random flat profile
20 - 2000 Hz (translational random flat profile) 16.3 GRMS
Note. This specification does not cover connection issues that may result from testing at this level.
b. Operating—abnormal
Equipment as installed for normal operation shall not incur physical damage while subjected to periodic
vibration:
Vibration occurring at these levels may degrade operational performance during the abnormal vibration
period. Specified operational performance will continue when normal operating vibration levels are
resumed. This assumes system recovery routines are available.
Operating abnormal translational random flat profile
20 - 2000 Hz (translational random flat profile) 16.3 GRMS
Note. This specification does not cover connection issues that may result from testing at this level.
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 vibration.
Vibration may be applied in the X, Y, or Z axis.
Non-operating translational random flat profile
20 - 2000 Hz (translational random flat profile) 16.3 GRMS
7.5.5 Air cleanliness
The drive is designed to operate in a typical office environment with minimal environmental control.
7.5.6 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.
