Particulate contamination Specications
Air ltration Data center air ltration as dened by ISO
Class 8 per ISO 14644-1 with a 95% upper
condence limit.
NOTE: This condition applies only to data center environments. Air ltration requirements do not apply to IT equipment
designed to be used outside a data center, in environments such as an oce 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 non-data 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 non-data center environments.

Gaseous contamination Specications
Copper coupon corrosion rate <300 Å/month per Class G1 as dened by ANSI/ISA71.04-2013
Silver coupon corrosion rate <200 Å/month per Class G1 as dened by ANSI/ISA71.04-2013
NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.
