The following section defines 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 specified 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 Specifications
contamination
Air filtration Data center air filtration as defined by ISO Class 8 per ISO 14644-1 with a 95% upper confidence limit.

Gaseous Specifications
contamination
Copper coupon <300 Å/month per Class G1 as defined by ANSI/ISA71.04-1985.
corrosion rate
Silver coupon <200 Å/month as defined by AHSRAE TC9.9.
corrosion rate
NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.
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.
NOTE: Air entering the data center must have MERV11 or MERV13 filtration.
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.
NOTE: Applies to data center and non-data center environments.
