Particulate contamination Specifications
NOTE: This condition applies to data center and non-data
center environments.
NOTE: Common sources of conductive dust include
manufacturing processes, and zinc whiskers from the
plating on the bottom of raised floor tiles.
Corrosive dust
Air must be free of corrosive dust.
Residual dust present in the air must have a deliquescent
point less than 60% relative humidity.
NOTE: This condition applies to data center and non-data
center environments.
