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 specification: 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 specification: 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.

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.

Copper coupon corrosion rate <300 Å/month per Class G1 as defined by
ANSI/ISA71.04-1985.
Silver coupon corrosion rate <200 Å/month as defined by AHSRAE TC9.9.
Note: Maximum corrosive contaminant levels measured at ≤50% relative humidity.
Standard operating temperature
The standard operating temperature for altitude less than 950 meters or 3117 feet ranges from
10°C to 35°C (50°F to 95°F) with no direct sunlight on the equipment.
