Particulate and gaseous contamination specifications
The following table defines the limitations that help avoid any equipment damage or failure from particulates and gaseous
contamination. If the level of particulates or gaseous pollution exceed the specified limitations and result in equipment damage
or failure, you may need to rectify the environmental conditions. Re-mediation of environmental conditions is the responsibility
of the customer.
Table 30. Particulate contamination specifications
Particulate contamination Specifications
Air filtration Data center air filtration as defined by ISO Class 8 per ISO
14644-1 with a 95% upper confidence limit.
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 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.
