The following section denes the limits to help avoid IT equipment damage and/or failure from particulates and gaseous contamination. If
the levels of particulates or gaseous pollution are beyond the specied limits and cause equipment damage or failure, you may need to
rectify the environmental conditions. Remediation of environmental conditions is the responsibility of the customer.
Particulate
contamination
Specications
Air ltration Data center air ltration as dened by ISO Class 8 per ISO 14644-1 with a 95% upper condence limit.
NOTE: Applies to data center environments only. Air ltration requirements do not apply to IT equipment
designed to be used outside a data center, in environments such as an oce or factory oor.
NOTE: Air entering the data center must have MERV11 or MERV13 ltration.
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.

Copper coupon
corrosion rate
<300 Å/month per Class G1 as dened by ANSI/ISA71.04-1985.
Silver coupon
corrosion rate
<200 Å/month as dened by AHSRAE TC9.9.
NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.
