Particulate and gaseous contamination specifications
The following table defines the limitations that will help avoid any damages to the IT equipment and/or
failure from particulates and gaseous contamination. If the levels 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.

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 to data center
environments only. 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 nondata
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 nondata
center environments.
