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. Remediation of
environmental conditions is the responsibility of the customer.
Air filtration specification: Data center air filtration as defined by ISO Class 8 per ISO
14644-1 should have 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 specification: 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 specification: Air must be free of
