If the levels of particulates or gaseous pollution exceed thespecified limitations and result in equipment damage or failure, you may need to rectify theenvironmental conditions. Re-mediation of environmental conditions is the responsibility of thecustomer.Table 23. Particulate contamination specificationsParticulate contamination SpecificationsAir filtration Data center air filtration as defined by ISO Class 8 per ISO14644-1 with a 95% upper confidence limit.NOTE: This condition applies to data centerenvironments only. Air filtration requirements do notapply to IT equipment designed to be used outside adata center, in environments such as an office orfactory floor.NOTE: Air entering the data center must haveMERV11 or MERV13 filtration.Conductive dust Air must be free of conductive dust, zinc whiskers, orother conductive particles.NOTE: This condition applies to data center andnon-data center environments.Corrosive dust • Air must be free of corrosive dust.• Residual dust present in the air must have adeliquescent point less than 60% relative humidity.25
