Full Description

ASHRAE Standard 72 prescribes a uniform method of testing open and closed refrigerators and freezers for rating so that comparative evaluations can be made of energy consumption, product temperature performance, refrigeration load, the suction pressures required, and other performance factors.

This 2022 revision has been reorganized to make the standard easier to read and use. It includes updates in the loading of test simulators and filler material, the sequence of operations during the test; and the instructions for some measurements. It also adds provisions for roll-in racks.
