Particulate and gaseous contamination specifications
The following table defines the limitations that prevent the damage to the IT equipment and/or, or both failure from particulate
and gaseous contamination. If the levels of particulate or gaseous pollution exceed the specified limitations and results in
equipment damage or failure, you must rectify the environmental conditions. Remediation of environmental conditions is the
responsibility of the customer.
Table 30. Particulate contamination specifications
Particulate contamination Specifications
Air filtration Data center air filtration as defined by ISO Class 8 per ISO
14644-1 with a 95% upper confidence limit.
NOTE: This condition 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.
NOTE: Air entering the data center must have MERV11 or
MERV13 filtration.
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.
Table 31. Gaseous contamination specifications
Gaseous contamination Specifications
Copper Coupon Corrosion rate <300 Å/month per Class G1 as defined by ANSI/
ISA71.04-2013
Silver Coupon Corrosion rate <200 Å/month as defined by ANSI/ISA71.04-2013
NOTE: Maximum corrosive contaminant levels measured at 50% relative humidity.
