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.
|
Gaseous
Contamination
|
-
NOTE: Maximum corrosive contaminant
levels measured at ≤50% relative humidity.
|
|
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.
