5 Conditions for the tests
5.1 General Each machine intended to be tested shall be representative of stock or routine production and shall be typical in construction and have only default settings as supplied on delivery to the customer, except as required to meet 5.6 and to achieve the operational modes required under 6.3. Machines are to be prepared in accordance with the manufacturer’s instructions as if they were to be installed in their intended vending location, including the fitting of parts such as leg covers and spacers. Unless otherwise specified, the tests are carried out on a single machine that shall withstand all the relevant tests, and are carried out in the order given in this document. Machines are to be categorised in accordance with the information in the manufacturer’s brochure. A machine described as being capable of being operated as a chilled food machine and fitted with a health cut-out function shall be tested as a category 3 machine. A machine described as providing the facility for a compartment to sell perishable food, and whose compartment is fitted with a health control cut-out function, shall be tested as a category 4 machine. Where a machine is fitted with a chiller but where no reference is made to perishable food, it shall be tested as a category 2 machine. All carousel or drum machines (where the products on display are held on a circular disc) fitted with a chiller are to be tested as category 3 machines. As far as possible, combination machines shall be supplied by the manufacturer with half the total volume set up for each category of machine, e.g. half as can/bottle and half as snack.
If it is evident from the construction of the machine that a particular test is not applicable, the test is not carried out. NOTE For example, in a category 5 machine, there is no reloading or pull-down measurement. 5.2 Equipment location for test Figure B.1 shows the position of the machine in the test room. The machine is to be installed so that the rearmost part of the cabinet is at a minimum of 1 00 mm from any vertical surface at the rear of the machine. There shall be a minimum of 1 m between the side or front of the machine casing and any vertical surface at the side or front of the machine. There shall be a minimum of 250 mm between the top of the machine and the ceiling of the test room.
5.3 Energy consumption and recording The energy consumption shall be measured by a direct meter reading method, as described in EN 50564 and recorded in the test report shown in Annex B.
5.4 M-cans M-cans shall be commercial 330 ml cans having height of 1 1 5 mm and a diameter 66 mm and shall be filled with water or a liquid of similar heat capacity and with a temperature sensor at the geometric centre of the can. NOTE If a different can size is used, this is stated in the test report. Only results determined with the same can size are comparable. For category 1 machines, two M-cans are placed in the columns adjacent to the outer columns of the product stack. Thus, they shall be placed in columns 2 and 4 of a 5-column machine. They shall be placed in the fourth row from the bottom of the stack, or if there are fewer than 4 rows, in the top row. For category 2 and 3 and 5 machines, 1 2 M-cans shall be placed at the extremes of the cabinet and in the middle row. For category 4 machines, M-cans shall be placed at the extremes of the uppermost and lowest rows of each compartment, for a total of 1 6 M-cans. For category 6 machines, M-cans shall be placed as appropriate for the two individual sections. Glass-fronted carousel vending machines shall be set up with 1 2 M-cans, four located equidistant in each of the top, middle and bottom rows. M-cans are required for the testing of category 5 machines to ensure that the product is at the correct temperature before testing starts.
5.5 Product loading for test Glass-fronted spiral or tray machines shall be set up entirely with spirals or trays so as to vend only 330 ml cans. Carousel or drum machines are to be set up with the maximum number of sectors that are large enough to contain a 330 ml can. Closed-fronted can/bottle machines are to be set up to contain the maximum number of 330 ml cans. Machines are to be filled with the maximum capacity number of 330 ml cans. The capacity shall be reported in the test report (see Annex B).IEC 63252 pdf download.
