contamination
Specifications
Conductive dust
Air must be free of conductive dust, zinc whiskers, or other conductive particles.
NOTE:
This condition applies to data center and non-data center environments.
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.
