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.

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 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.

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.

● 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 non-data

center environments.
