6.5.4.2
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 shaped profile
20 - 2000 Hz
11.08 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 shaped profile
20 - 2000 Hz
11.08 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 shaped profile
20 - 2000 Hz
11.08 GRMS
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 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 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 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.
