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 and/or failures to your equipment it may be necessary for you to remediate the environmental conditions that are causing the damage and/or failures. Remediation of environmental conditions will be the responsibility of the customer.
Air Filtration
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.
Data center air filtration as defined by ISO Class 8 per ISO
NOTE: Air entering the data center must have MERV11 or MERV13 filtration.
Conductive Dust | Air must be free of conductive dust, zinc whiskers, or |
NOTE: Applies to data center and | other conductive particles. |

Corrosive Dust
NOTE: Applies to data center and
Gaseous Contamination
•Air must be free of corrosive dust.
•Residual dust present in the air must have a deliquescent point less than 60% relative humidity.
NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity
Copper Coupon Corrosion Rate | <300 Å/month per Class G1 as defined by ANSI/ |
