Environmental

40 °C to 45 °C (104 °F to 113 °F)

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 re-mediate the environmental conditions that are causing the damage and/or failures. Re-mediation 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.

Conductive Dust

NOTE: Applies to data center and non-data center

environments.

Corrosive Dust

NOTE: Applies to data center and non-data center

environments.

Gaseous Contamination

NOTE: Maximum corrosive contaminant levels measured at ≤50% relative humidity.

Copper Coupon Corrosion Rate

Silver Coupon Corrosion Rate

Maximum temperature is reduced by 1 °C/125 m (1 °F/228

ft) above 950 m (3,117 ft).

Data center air filtration as defined by ISO Class 8 per

ISO 14644-1 with a 95% upper confidence limit.

NOTE: Air entering the data center must have

MERV11 or MERV13 filtration.

Air must be free of conductive dust, zinc whiskers, or

other conductive particles.

•

Air must be free of corrosive dust.

•

Residual dust present in the air must have a

deliquescent point less than 60% relative

humidity.

<300 Å/month per Class G1 as defined by ANSI/

ISA71.04-1985.

<200 Å/month as defined by AHSRAE TC9.9.
