Particulate and gaseous contamination specifications

The following table defines the limitations that help avoid any damages to the IT equipment and/or, or both failure from
particulate and gaseous contamination. If the levels of particulate or gaseous pollution exceed the specified limitations and
results in equipment damage or failure, you must rectify the environmental conditions. Remediation 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:
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:
MERV13 filtration.
NOTE:
room air with MERV8 filter per ANSI/ASHARE Standard
127.
Air must be free of conductive dust, zinc whiskers, or other
conductive particles.
This condition applies to data center environments
Air entering the data center must have MERV11 or
Air filtering can also be accomplished by filtering
