Particulate and gaseous contamination specificationsThe following table defines the limitations that help avoid any damages to the IT equipment and/or, or both failure from particulate andgaseous contamination. If the levels of particulate or gaseous pollution exceed the specified limitations and results in equipment damage orfailure, you must rectify the environmental conditions. Remediation of environmental conditions is the responsibility of the customer.Table 19. Particulate contamination specificationsParticulate contaminationSpecificationsAir filtrationData center air filtration as defined by ISO Class 8 per ISO 14644-1with a 95% upper confidence limit.NOTE: This condition applies to data center environmentsonly. Air filtration requirements do not apply to ITequipment designed to be used outside a data center, inenvironments such as an office or factory floor.NOTE: Air entering the data center must have MERV11 orMERV13 filtration.Conductive dustAir must be free of conductive dust, zinc whiskers, or otherconductive particles.NOTE: This condition applies to data center and non-datacenter environments.Corrosive dust Air must be free of corrosive dust.Residual dust present in the air must have a deliquescent pointless than 60% relative humidity.NOTE: This condition applies to data center and non-datacenter environments.Table 20.
