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.

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).
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.
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.
NOTE: Applies to data center and non-data center environments.
Air must be free of conductive dust, zinc whiskers, or other conductive
particles.
NOTE: Applies to data center and non-data center environments.
• Air must be free of corrosive dust.
• Residual dust present in the air must have a deliquescent point less than
60% relative humidity.
<300 Å/month per Class G1 as defined by ANSI/ISA71.04-1985.
<200 Å/month as defined by AHSRAE TC9.9.
