"2011 Thermal Guidelines for Liquid Cooled Data Processing Environments"
 Whitepaper prepared by ASHRAE Technical Committee (TC) 9.9
 Mission Critical Facilities, Technology Spaces, and Electronic Equipment

Executive Summary (Page 2)
"ASHRAE TC 9.9 created the first edition of the "Thermal Guidelines
 for Data Processing Environments" in 2004." ...

"TC 9.9 has recently published (May, 2011) a further update described
 in a whitepaper available on TC 9.9’s website. The whitepaper
 documents expanded data center environmental guidelines by adding
 two more envelopes that are wider in temperature and humidity.

 However, these guidelines are for air-cooled IT equipment and do not
 address water temperatures provided by facilities for supporting liquid
 cooled equipment here" ....

"This document describes classes for the temperature ranges of the
 facility supply of water to liquid cooled IT equipment. In addition,
 this document reinforces some of the information provided in the Liquid
 Cooling Guidelines book on the interface between the IT equipment and
 infrastructure in support of the liquid cooled IT equipment."
