Consensus requires that all views and objections be considered, and that an effort be made toward their resolution.”Compliance with this Standard is voluntary until and unless a legal jurisdiction makes compliance mandatory through legisla
6、tion. ASHRAE obtains consensus through participation of its national and international members, associated societies, and public review.ASHRAE Standards are prepared by a Project Committee appointed specifically for the purpose of writing the Standard.

21、1 has been peri-odically updated to respond to changes in machine and pack-age design. Key changes in the 2017 edition are as follows: Updated scope and definitions to emphasize intendedapplication to refrigerated beverage vending machinesand combination machines. Removed distinctions between zone-c
22、ooled (typicallysolid-front) machines and fully cooled (typically glass-front) machines, as these distinctions are not necessaryfor conducting the test. Updated references to other documents, including themethodology for measuring refrigerated volume. Enhanced instrumentation calibration and accurac
23、yrequirements. Removed the 90F (32.2C) ambient condition for theenergy consumption test and designated the 75F(23.9C) ambient condition as the singular test condi-tion. Clarified test setup requirements, including ambient tem-perature measurement location, beverage temperaturelocations, test package
24、 construction, and sensor wireinstallation. Incorporated minimum functionality requirements thatmust be included and the controls that are permitted inthe vending machine under test. Clarified the method for calculating integrated averagetemperature.In addition, various editorial changes have been i
25、mple-mented to improve clarity.1. PURPOSEThe purpose of this standard is to specify methods of testingfor rating the capacity and efficiency of self-contained,mechanically refrigerated vending machines for sealed bever-ages.2. SCOPEThis standarda. establishes uniform methods of testing for determini
26、nglaboratory performance of refrigerated beverage vendingmachines;b. applies to refrigerated beverage vending machines andcombination machines; c. does not apply to climate-controlled snack vendingmachines, frozen-food vending machines, refrigerated-food-served-hot vending machines, or hot-beverage
27、vend-ing machines; d. lists and defines the terms used in the methods of testing; e. defines standard sealed-beverage storage capacity; andf. establishes test conditions for rating.3. DEFINITIONSactive mode: the state of normal operation of the vendingmachine where the cooling system is active, merc
