The following 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.
Particulate contamination
Specifications
Air filtration
Data center air filtration as defined by ISO Class
8 per ISO 14644-1 with a 95% upper confidence limit.
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.
NOTE:Air entering the data
center must have MERV11 or MERV13 filtration.
Conductive Dust
Air must be free of conductive dust, zinc whiskers,
or other conductive particles.
NOTE:Applies to data center
and non-data center environments.
Corrosive Dust
Air must be free of corrosive dust.
Residual dust present in the air must have a deliquescent
point less than 60% relative humidity.
NOTE:Applies
to data center and non-data center environments.
Gaseous contamination
Specifications
Copper coupon corrosion rate
<300 Å/month per Class G1 as defined by ANSI/ISA71.04-1985.
Silver coupon corrosion rate
<200 Å/month as defined by AHSRAE TC9.9.
NOTE:Maximum
corrosive contaminant levels measured at ≤50% relative humidity.
