environmental conditions. Re-mediation of environmental conditions is the responsibility of thecustomer.Table 29. 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.NOTE: This condition applies to data center andnon-data center environments.Table 30. Gaseous contamination specificationsGaseous contamination SpecificationsCopper coupon corrosion rate <300 Å/month per Class G1 as defined by ANSI/ISA71.04-1985.Silver coupon corrosion rate <200 Å/month as defined by AHSRAE TC9.9.NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.Standard operating temperatureTable 31. Standard operating temperature specificationsStandard operating temperature SpecificationsContinuous operation (for altitude less than950 m or 3117 ft)10°C to 35°C (50°F to 95°F) with no direct sunlight on theequipment.NOTE: The 2.5-inch hard drive chassis supports amaximum of 145 W processors.38
