Particulate and gaseous contamination specifications

Table 26. Particulate contamination specifications
Particulate contamination
Air filtration
NOTE: This condition applies only to data center environments. Air filtration requirements do not apply to IT equipment
designed to be used outside a data center, in environments such as an office or factory floor.
NOTE: Air entering the data center must have MERV11 or MERV13 filtration.
Conductive dust
NOTE: This condition applies to data center and non-data center environments.
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.
