Particulate and gaseous contamination specifications
The following table defines the limitations that prevent any equipment damage or 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 32. 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.
Walk-Up Edge Data Center or Cabinet (sealed, closed loop
environment)
Filtration is not required for cabinets that are anticipated to
be opened 6 times or less per year. Class 8 per ISO 1466-1
filtration as defined above is required otherwise
NOTE: In environments commonly above ISA-71 Class G1
or that may have known challenges, special filters may be
required.
