Specifications
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.
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.
• 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.
Specifications
<300 Å/month per Class G1 as defined by ANSI/ISA71.04-1985.
