Hah. Found it. Near the top of this web site http://tc99.ashraetcs.org/ there is a link to download a presentation. On slide 29 is the following table: Environmental Conditions ASHRAE Thermal Guidelines for Data Processing Environments Table 2.1 Equipment Environment Specifications Class | Allowable | Recommended | Allowable | Recommended | Dry Bulb | Dry Bulb | % Relative | % Relative | (°C) | (°C) | Humidity | Humidity ------------------------------------------------------------ 1 | 15 to 32 | 20 to 25 | 20 to 80 | 40 to 55 2 | 10 to 35 | 20 to 80 | 20 to 80 | 40 to 55 3 | 5 to 35 | NA | 8 to 80 | NA 4 | 5 to 40 | NA | 8 to 80 | NA Unfortunately, the classification of facilities is not discussed, but I'll assume for the moment that most folks are interested in the Class 1 facility recommendation, as the line for Class 2 seems a bit absurd, and the Class 3 and 4 lines are way out of scope, IMHO Kurt ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~
