4.2.2 Defrosting The proposed defrosting procedures (automatic or manual) shall not affect the temperature requirements (see 5.3.4). 4.2.3 Water vapour condensation The presence of water vapour condensation shall be verified according to the conditions and test methods specified in 5.3.5. 4.2.4 Electrical energy consumption The electrical energy consumption (E24h) shall be measured over 24 h period according to the conditions and the test methods specified in 5.3.6. The energy consumption shall be expressed in kWh/24h rounded to two decimal places. 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).BS EN 16825 pdf download.
