The test consists of 15 minutes of random vibration using the power spectral density (PSD) levels specified in 
the table below. The vibration test level is 3.01 Gs RMS. The drive will not incur any physical damage when 
subsequently put into operation.

Seagate electronic drive components pass accelerated corrosion testing equivalent to ten years of 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 percent. 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.
