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.

Consommation d'énergie des distributeurs automatiques
Le présent document définit des méthodes de mesure de la consommation d'énergie des distributeurs automatiques, qu'ils soient équipés ou non d'appareils de réfrigération. La norme s'applique (entre autres) aux catégories de distributeurs présentées dans le Tableau 1. Les types de distributeurs automatiques suivants ne sont pas couverts par la présente norme: — distributeurs de boissons chaudes et/ou froides dans des gobelets; — distributeurs avec une fonction de chauffage des denrées; — distributeurs automatiques fonctionnant à des températures inférieures à 0 °C; ou — tout distributeur comprenant un ou plusieurs de ces compartiments. À des fins de vérification, il est indispensable d’appliquer tous les essais spécifiés à un seul appareil. Les essais peuvent également être effectués séparément pour l'étude d'une caractéristique particulière. La présente norme ne couvre pas les caractéristiques de conception du distributeur autres que la consommation d'énergie.
Poraba energije prodajnih avtomatov

170 4 General requirements171 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 tofood 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 cooling6 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 mountedone 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.

186 4.2 Test room
187 Tests shall be carried out in a test room at climate class (3, 25 ± 1) °C and (60 ± 5) % relative humidity with
188 defined air movement. The conditions in the test room shall be measured by a probe located 500 mm
189 upstream of the vending machine (on the air supply side of the cabinet) in line with the front of the cabinet
190 and at half the height of the vending machine being tested.191 Lighting shall be installed to maintain (600 ± 100) lx measured at a height of 1 m above the floor level.
192 Air movement shall be provided. The air movement shall be, as far as practicable, parallel to the plane of the
193 cabinet opening and to the horizontal axis. The air velocity at any point on the vertical side of the vending
194 machine shall be between 0,1m/s and 0,2 m/s.195 The direction of air flow shall be such that the air does not enter the cabinet when the door is open.
196 4.3 Instruments, measuring equipment and measuring accuracy197 All measurement shall be carried out with instruments that have been calibrated.
198 Temperature measurements shall be made to an accuracy of ±1 °C. The time interval between temperature
199 measurements should be no greater than 1 min.200 Time measurements shall be made to the nearest [0.01] hours.
201 Relative humidity shall be measured to an accuracy of ± 5 %.
202 Electrical energy consumption shall be measured to a resolution of ± 0,01 kWh and with an accuracy of
203 ± 1 %.204 NOTE See EN 50564 for guidance on power measurement.
