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 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 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.
