Energy consumption of vending machines

This document 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 categories shown in Table 1 of machine types. The following types of vending machine are excluded from this standard: — 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 may also be made individually for the study of a particular characteristic. This standard does not deal with any characteristics of machine design other than energy consumption.

This document supersedes EN 50597:2015.

EN 50597:2018 includes the following significant technical changes with respect to EN 50597:2015:

The ambient test conditions have been harmonised with those in other related standards. The order of tests

has been modified to make the testing less time consuming and more efficient. This revised standard

includes an extra category of machine: one divided vertically into two compartments each with different

functions.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

Introduction

Vending machines are included in the European Commission’s eco-design study on ENER Lot 12. It is

foreseen that an Ecodesign Regulation implementing Directive 2009/125/EC on the eco-design of energy-

related products will be adopted in the future, and a corresponding standardization request will be issued to

CEN and CENELEC accordingly. The development of the present European Standard was deemed

necessary in order to anticipate the above-mentioned developments.

1 Scope

This document 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 categories shown in Table 1 of machine types.

Table 1 — Vending machine categories
CATEGORY MACHINE TYPE
1 Refrigerated closed fronted can and bottle machines where the products
are held in stacks
2 Refrigerated glass fronted can and bottle, confectionery & snack
machines
3 Refrigerated glass fronted machines entirely for perishable foodstuffs
4 Refrigerated dual-temperature glass fronted machines
5 Confectionery and snack machines that are not refrigerated
6 Combination machines consisting of two different categories of machine

The following types of vending machine are excluded from this standard:
— 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 may also

be made individually for the study of a particular characteristic.

This standard does not deal with any characteristics of machine design other than energy consumption.

50 related products will be adopted in the future, and a corresponding standardization request will be issued to

51 CEN and CENELEC accordingly. The development of the present European Standard was deemed

52 necessary in order to anticipate the above-mentioned developments.

53 1 Scope

54 This European Standard defines methods for the measurement of energy consumption of vending machines,

55 whether or not fitted with refrigerating appliances.

56 The standard applies (but is not limited) to the categories shown in Table 1 of machine types.

57 Table 1 — Vending machine categories
CATEGORY MACHINE TYPE
1 Refrigerated closed fronted can and bottle machines where the products
are held in stacks
2 Refrigerated glass fronted can and bottle, confectionery & snack
machines
3 Refrigerated glass fronted machines entirely for perishable foodstuffs
4 Refrigerated dual-temperature glass fronted machines
5 Confectionery and snack machines that are not refrigerated
6 Combination machines consisting of two different categories of machine
in the same housing and powered by one chiller

58 For verification purposes, all of the tests specified are to be applied to a single unit. The tests may also be

59 made individually for the study of a particular characteristic.

60 This standard does not deal with any characteristics of machine design other than energy consumption.

170 4 General requirements
171 4.1 Applicability

172 This European Standard establishes the tests and calculations necessary to determine the energy rating of a

173 vending machine.

174 The standard relates to the categories of vending machines described in Table 2 and to any combination of

175 them.
176 Table 2 — Description of vending machine categories
CATEGORY MACHINE TYPE COMMENT
1 Refrigerated closed fronted can and bottle These machines serve refrigerated
machines where the products are held in beverages that are not visible before
stacks vending.

2 Refrigerated glass fronted can and bottle, These machines are for foodstuffs which

confectionery & snack machines are refrigerated for reasons not related to
food safety
3 Refrigerated glass fronted machines These machines are refrigerated for food
entirely for perishable foodstuffs safety reasons and have a health control
cut-out function
4 Refrigerated dual-temperature glass These machines have two compartments,
fronted machines each of which is held at a different
temperature, one of which is for perishable
food. The compartment containing
perishable food must be controlled by a
health control cut-out function.

5 Confectionery and snack machines that are These machines store product at ambient

not refrigerated temperature without cooling
6 Combination machines consisting of two The machines usually consist of two

different categories of machine in the same machine modules separated by a vertical

housing and powered by one chiller. panel but could also be two units mounted
one above the other. Typical combination
machine would consist of a closed fronted
bottle machine and a glass fronted snack
machine, or two separate food and snack
machines.
177 The following types of vending machine are excluded from this standard:
178 — drink machines dispensing hot and/or cold drinks into cups;
179 — machines with a food heating function;
180 — vending machines operating at temperatures below 0 °C; or
181 — any machine including one or more of these compartments.

182 The machine manufacturer shall provide adequate information to confirm that the machine is suitable for

183 testing according to this specification and that it can perform the tests as required, if necessary with minimum

184 intervention by manufacturers’ technical staff.
185 Information shall be provided by completing the test report in Annex B.
