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.
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.
Conductive Dust
NOTE: Applies to data
center and non-data
center environments.
Air must be free of conductive dust, zinc whiskers, or other
conductive particles.
Corrosive Dust
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.
