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.
