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
0.26 G at 5 Hz to 350 Hz (all operation
rms
orientations).
1.87 G at 10 Hz to 500 Hz for 15 min (all six
rms
sides tested).
One shock pulse in the positive z axis of 31 G
for 2.6 ms in all operational orientations.
Six consecutively executed shock pulses in the
positive and negative x, y, and z axes (one pulse
on each side of the system) of 71 G for up to 2
ms.
3,048 m (10,000 ft)
12,000 m (39,370 ft).
Maximum temperature is reduced by 1 °C/300
m (1 °F/547 ft) above 950 m (3,117 ft).
Maximum temperature is reduced by 1 °C/175
m (1 °F/319 ft) above 950 m (3,117 ft).
Maximum temperature is reduced by 1 °C/125
m (1 °F/228 ft) above 950 m (3,117 ft).
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.
