Table 4-1 Controlled Computer Room Environment Specifications

Temperature (dry bulb ^οC)^[1]		Relative Humidity %; Non condensing		Dew Point^[2]	Rate of Change (˚C/hr., max)
Allowable^[3]^,^[4]	Recommended^[5]	Allowable^[4]	Recommended^[5]
15 to 32 (59^ο to 90^ο F)	20 to 25 (68^ο to 77^ο F)	20 to 80	40 to 55	17	5
^[1]Dry bulb temperature is the regular ambient temperature. Derate maximum dry bulb temperature 1˚C/300 m above 900 m. ^[2]Must be non-condensing environment. ^[3]With installed media, the minimum temperature is 15˚C and maximum relative humidity is limited to 80%. Specific media requirements may vary. ^[4]Allowable: equipment design extremes as measured at the equipment inlet. ^[5]Recommended: target facility design and operational range.

Storage			Powered Off (installed)
Temp (˚C, dry bulb - regular ambient temp.)	Relative Humidity % Non-condensing	Dew point (max)	Temp (˚C, dry bulb - regular ambient temp.)	Relative Humidity % Non-condensing	Dew point (max)
-40 to +60	8 to 90	32	5 to 45^[1]	8 to 90	29
^[1]The room ambient temperature must be returned to normal operating conditions and sufficient time is given for the equipment to return to thermal equilibrium and stabilize.
