ANSI/ASHRAE Standard 32.1-2017 – Testing Refrigerated Vending Machines for Sealed Beverages
ANSI/ASHRAE Standard 32.1 has been the official standard for specifying test methods for refrigerated beverage vending machines since its first publication in 1982. The latest edition of this standard, ANSI/ASHRAE Standard 32.1-2017 – Methods of Testing for Rating Refrigerated Vending Machines for Sealed Beverages.
ANSI/ASHRAE Standard 32.1-2017 addresses testing methods for rating the capacity and efficiency of self-contained, mechanically refrigerated vending machines for sealed beverages. These laboratory methods for determining performance are applicable only to refrigerated beverage vending machines and combination machines; they are not to be used for climate-controlled snack vending machines, frozen-food vending machines, refrigerated-food-served-hot vending machines, or hot-beverage vending machines.
There are close to 7 million vending machines active in the United States, accumulating tens of millions of dollars for the industry, with cold drinks occupying 56 percent of all sales.
These existing machines are modern representatives of the longstanding tradition of expedited food and beverage transactions, as vending machines as we know them today appeared in abundance in the 1930s.

ANSI/ASHRAE Standard 32.1-2017 – Testing Refrigerated Vending Machines for Sealed Beverages Updates:
- Updated scope and definitions to emphasize intended application to refrigerated beverage vending machines and combination machines also .
- Removed distinctions between zone-cooled machines and fully cooled machines also.
- Updated references to other documents, including the methodology for measuring refrigerated volume.
- Enhanced instrumentation calibration and accuracy requirements also.
- Removed the 90°F (32.2°C) ambient condition for the energy consumption test and designated the 75°F (23.9°C) ambient condition as the singular test condition.
- Clarified test setup requirements, including ambient temperature measurement location, beverage temperature locations, test package construction, and sensor wire installation also.
- Incorporated minimum functionality requirements that must included and the controls that permitted in the vending machine under test.
- Clarified the method for calculating integrated average temperature.
- Added various editorial changes to improve clarity.
- The alterations made to this new version correspond with the changes in machine and package design also.
The actual methods for carrying out the testing procedures for rating the machines, information for filling out the reporting form of tested equipment, any relevant terms, and explanations of vending machine capacity also are detailed in ANSI/ASHRAE Standard 32.1-2017.
