Particulate and gaseous contamination specifications

The following table defines the limitations that help avoid any equipment damage or failure from particulate and gaseous contamination. If
the levels of particulate or gaseous pollution exceed the specified limitations and result in equipment damage or failure, you may need to
rectify the environmental conditions. Remediation of environmental conditions is the responsibility of the customer.

Specifications
Data center air filtration defines, ISO Class 8 per ISO 14644-1 with a 95% upper confidence limit.
NOTE: The ISO Class 8 condition applies to data center environments only. This air filtration
requirement does 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 nondata 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 nondata center environments.
