Particulate
and gaseous contamination specifications
The following
table defines the limitations that help avoid any damages to
the IT equipment and/or, or both failure from particulate and gaseous contamination.
If the levels of particulate or gaseous pollution exceed the specified
limitations and results in equipment damage or failure, you must rectify the environmental conditions. Remediation of environmental
conditions is the responsibility of the customer.
Table 1. Particulate
contamination specifications Air filtration specification: Data center air filtration
as defined by ISO Class 8 per ISO 14644-1 should have a 95% upper
confidence limit. This condition applies only to data center
environments. 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. Air entering the data center must
have MERV11 or MERV13 filtration. Conductive dust specification: Air
must be free of conductive dust, zinc whiskers, or other conductive
particles. This condition applies to data center and non-data
center environments. Corrosive dust specification: Air must be free
of corrosive dust. Residual dust present in the air must have a deliquescent
point less than 60% relative humidity. This condition applies
to data center and non-data center environments.
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 This condition
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 This condition 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 This condition
applies to data center and non-data center environments.
Table 2. Gaseous contamination
specifications The copper coupon corrosion rate is <300 Å/month
per Class G1 as defined by ANSI/ISA71.04-1985. The silver coupon corrosion
rate is <200 Å/month as defined by AHSRAE TC9.9.

Specifications
Copper Coupon Corrosion
<300 Å/month per Class G1 as defined by ANSI/ISA71.04-1985.
Silver Coupon Corrosion
<200 Å/month as defined by AHSRAE TC9.9.
NOTE Maximum
corrosive contaminant levels measured at ≤50% relative humidity.
