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.
