Particulate and gaseous contamination specifications
This section defines 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 specified 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.
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: The ISO Class 8 condition applies to data center environments only. This air
filtration requirement does 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 4. 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.
