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.
NOTE:
This section defines the limits to help avoid IT equipment damage and/or failure from particulates and gaseous
contamination. If it is determined that levels of particulates or gaseous pollution are beyond the limits specified in the
following table and are the reason for the damage and/or failures to your equipment, it may be necessary for you to
re-mediate the environmental conditions that are causing the damage and/or failures. Re-mediation of environmental
conditions will be the responsibility of the customer.

Specifications
Air Filtration
NOTE:
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.
Data center air filtration as defined by ISO Class 8 per
ISO 14644-1 with a 95% upper confidence limit.
NOTE:
Air entering the data center must have
MERV11 or MERV13 filtration.
Conductive Dust
NOTE:
Applies to data center and non-data center
environments.
Air must be free of conductive dust, zinc whiskers, or
other conductive particles.
Corrosive Dust
NOTE:
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.
