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.
