IEC 63252:2020定义了自动售货机能耗的测量方法，无论是否配备制冷设备。 本标准适用于（但不限于）以下类别的机器: -冷藏封闭式罐和瓶机，产品堆叠存放 -冷藏玻璃面罐头和瓶子、糖果和点心机 -完全用于易腐食品的冷藏玻璃面机器 -冷藏双温玻璃正面机器 -非冷藏的糖果和点心机 -在同一外壳中由两种不同类别的机器组成并由一个冷却器供电的组合机器 本文件不包括以下类型的自动售货机: -将热饮和/或冷饮分配到杯中的饮料机；-具有食物加热功能的机器； -温度低于0℃的自动售货机；或 -包括这些隔间中的一个或多个的任何机器。 出于验证目的，必须将指定的所有测试应用于单个单元。这些测试也可以单独进行，以研究特定的特性。 本文件不涉及除能耗以外的任何机器设计特征。

IEC 63252:2020 defines methods for the measurement of energy consumption of vending machines, whether or not fitted with refrigerating appliances.
The standard applies (but is not limited) to the following categories of machines:
- Refrigerated closed-fronted can and bottle machines where the products are held in stacks
- Refrigerated glass-fronted can and bottle, confectionery and snack machines
- Refrigerated glass-fronted machines entirely for perishable foodstuffs
- Refrigerated dual-temperature glass-fronted machines
- Confectionery and snack machines that are not refrigerated
- Combination machines consisting of two different categories of machine in the same housing and powered by one chiller
The following types of vending machine are excluded from this document:
- drink machines dispensing hot and/or cold drinks into cups;
- machines with a food-heating function;
- vending machines operating at temperatures below 0 °C; or
- any machine including one or more of these compartments.
For verification purposes, it is essential to apply all of the tests specified to a single unit. The tests can also be made individually for the study of a particular characteristic.
This document does not deal with any characteristics of machine design other than energy consumption.
