Particulate and gaseous contamination specications
The following table denes 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 specied 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.

Particulate contamination Specications
Air ltration Data center air ltration as dened by ISO Class 8 per ISO 14644-1 with a
95% upper condence limit.
NOTE: This condition applies to data center environments only. Air
ltration requirements do not apply to IT equipment designed to be
used outside a data center, in environments such as an oce or
factory oor.
