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
