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 or failures to your equipment, it maybe
necessary for you to re-mediate the environmental conditions that
are causing the damage or failures. Re-mediation of environmental
conditions will be the responsibility of the customer.
|
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.
|
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 |
|
-
NOTE: Maximum corrosive contaminant
levels measured at ≤50% relative humidity.
|
Copper coupon corrosion rate |
<300 Å/month per ClassG1 as defined by ANSI/ISA71.04-1985. |
Silver coupon corrosion rate |
<200 Å/month as defined by AHSRAE TC9.9. |
