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.

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 only to data center
environments. 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
l
Air must be free of corrosive dust.
l
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.
The copper coupon corrosion rate is <300 Å/month per Class G1 as defined by ANSI/
ISA71.04-1985. The silver coupon corrosion rate is <200 Å/month as defined by
AHSRAE TC9.9.
