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.

Specifications
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.
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.
• 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.
