Particulate contamination Specifications
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.

Gaseous contamination Specifications
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 specifications
Table 14. Standard operating temperature specifications
Standard operating temperature Specifications
Continuous operation (altitudes under 950 m / 3,117 ft) 10°C to 35°C (50°F to 95°F), avoiding direct sunlight
Expanded operating temperature specifications

Expanded operating temperature Specifications
≤10% of annual operating hours 5°C to 40°C (41°F to 104°F), avoiding direct sunlight on the equipment
NOTE: Outside the standard operating temperature (10°C to
35°C / 50°F to 95°F), the system can operate for a maximum of
10% of its annual operating hours in temperatures as low as 5°C
(41°F) and as high as 40°C (104°F).
