Translated by the ASHRAE Mexico City Chapter.

This standard was written to establish methods of temperature measurement that provide consistent procedures that may be referenced in other ASHRAE standards. There were no changes made for the 2006 reaffirmation. The purpose of this standard is to set forth recommended practices for temperature measurements and provide adequate and consistent measurement procedures for reference in other standards. The procedures described herein are intended for use in testing heating, refrigerating, and air-conditioning equipment and components. The media in which temperature measurements are made include air, water, brine, and volatile or nonvolatile refrigerants, under both steady-state and transient temperature conditions between -40ºF and 400ºF (-40ºC and 204ºC).
