Table 13. Particulate Contamination
NOTE: This section defines the limits to help avoid IT equipment damage and/or failure from
particulates and gaseous contamination. If it is determined that levels of particulates or gaseous
pollution are beyond the limits specified below and are the reason for the damage and/or failures
to your equipment, it may be necessary for you to re-mediate the environmental conditions that
are causing the damage and/or failures. Re-mediation of environmental conditions will be the
responsibility of the customer.
Air Filtration
NOTE: 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.
Conductive Dust
NOTE: Applies to data center and
non-data center environments.
Corrosive Dust
5% to 95% at a maximum wet bulb temperature of 33
°C (91 °F)
0.26 G
at 5 Hz to 350 Hz in operational orientation
rms
1.88 G
at 10 Hz to 500 Hz for 15 minutes (all six
rms
sides tested)
One shock pulse in the positive z axis of the system at
31 G for 2.6 ms in the operational orientation
Six consecutively executed shock pulses in the positive
and negative x, y, and z axes (one pulse on each side of
the system) at 71 G for up to 2 ms
Maximum 3000 m (9842.5 ft)
NOTE: For altitudes above 2950 ft, the maximum
operating temperature is derated 1.8 ºF/1000 ft.
Maximum 12192 m ( 40,000 ft)
G1 as defined by ISA-S71.04-1985
Data center air filtration as defined by ISO Class 8 per
ISO 14644-1 with a 95% upper confidence limit.
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.
•
Air must be free of corrosive dust.
