5 Test conditions
5.1 General
When the characteristics of a cabinet are to be verified, all the tests and inspections shall be applied to one and the same cabinet. These tests and inspections may also be made individually for the study of a particular characteristic.
Compartment(s) of a combined refrigerated cabinet that are not foreseen for storage of foodstuffs are not subjected to tests and verifications of this standard.
Table 2 lists the tests and verifications.
5.2 Tests outside test room The tests which may be carried out outside the test room deal with the inspection of construction characteristics and physical dimensions, linear dimensions, areas and volumes. Measurements shall be made with the cabinet not in operation but situated in a place where the temperature is maintained between 16 °C and 30 °C. If the cabinet includes permanent jacks, rollers, feet or other components for adjustment of height, they are considered in the measurement of the height of the cabinet. The height for counter shall not include the work top. 5.3 Tests inside test room
5.3.1 General The tests which are carried out inside the test room deal with the measurement of the following characteristics:
— temperature and defrosting;
— water vapour condensation;
— electrical energy consumption.
5.3.2 Test conditions
5.3.2.1 General In the following, general testing conditions which are common for all tests specified in Clause 6 carried out inside the test room are defined. These conditions concern the test room, the test and M-packages, and the measuring instruments.
5.3.2.2 Test room — General design, walls, floor and radiant heat The test room shall be a parallelepiped space. The walls of the room shall be thermally insulated. The minimum dimensions of the test room shall be such as to allow at least 0,5 m above the top of the cabinet, 1 m on the side of the climate measuring point, 0,5 m on the opposite side and 1,5 m on the front of the cabinet with doors in closed position (see Figure 4). A minimum insulation level equivalent to 60 mm of rigid polyurethane foam (λ = 0,03 W/m °C) should be used for the building of the test room.
The floor shall be made of concrete or of thermally equivalent material and/or shall be sufficiently insulated to ensure that external climatic conditions do not affect the floor temperature. Lighting shall be installed to maintain (600 ± 100) lx measured at a height of 1 m above the floor level and shall be lit continuously during the test period. The walls, ceilings and any partitions of rooms intended for the testing of refrigerated cabinets shall have an emissivity between 0,9 and 1 at 25 °C.
5.3.2.3 Test room climate definition
5.3.2.3.1 Test room climate classes Tests shall be carried out in one of the climate classes according to Table 3. During the test, the test room shall be capable of maintaining values of temperature and humidity within ± 1 °C of the temperature and ± 5 units of the relative humidity percentage figures at the specified climate measuring point(s).
5.3.2.3.2 Climate measuring point The climate measuring point shall be located in the test room air flow, 500 mm upstream of the cabinet (i.e. on the air supply side of the cabinet), in line with the front of the cabinet at a vertical height that is half the cabinet height (including cabinet feet and fixings). To avoid undue influence from the movement of doors or of doors operating means, for the value of the relative humidity, the mean of the relative humidity values measured during 1 min shall be considered. The warm condenser air flow shall be prevented from influencing the temperature at the measuring point by air deflectors or other suitable means. Positioning and type of air deflectors if any shall be indicated. This information is included in the information foreseen in Annex A.BS EN 16825 pdf download.
