Particulate and gaseous contamination specications
The following table denes the limitations that help avoid any equipment damage or failure from particulate and gaseous contamination. If
the levels of particulate or gaseous pollution exceed the specied 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.

Air ltration Data center air ltration denes, ISO Class 8 per ISO 14644-1 with a 95% upper condence limit.
NOTE: The ISO Class 8 condition applies to data center environments only. This air ltration
requirement does not apply to IT equipment designed to be used outside a data center, in
environments such as an oce or factory oor.
NOTE: Air entering the data center must have MERV11 or MERV13 ltration.
Conductive dust Air must be free of conductive dust, zinc whiskers, or other conductive particles.
NOTE: This condition applies to data center and nondata center environments.
Corrosive dust
• 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 nondata center environments.

Copper coupon corrosion rate <300 Å/month per Class G1 denes, ANSI/ISA71.04-2013.
Silver coupon corrosion rate <200 Å/month denes, ANSI/ISA71.04-2013.
NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.
