Particulate and gaseous contamination specifications

The following table defines the limitations that help avoid any equipment damage or failure from particulates and gaseous
contamination. If the levels of particulates or gaseous pollution exceed the specified limitations and result in equipment damage
or failure, you may need to rectify the environmental conditions. Re-mediation of environmental conditions is the responsibility
of the customer.

Specifications
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.
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.
● 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.
Specifications
<300 Å/month per Class G1 as defined by ANSI/ISA71.04-1985.
<200 Å/month as defined by AHSRAE TC9.9.
Specifications
10°C to 35°C (50°F to 95°F) with no direct sunlight on the
equipment.
