The dry cooling capacity shall be quoted as a function of the temperature difference between the reference temperature and the average cooling water temperature. The test is carried out in a testing system according to EN 442-2, which consists of a closed booth with controlled temperatures of the inside surfaces and a secondary master radiator for dry cooling capacity (see 4.4). All laboratories performing tests according to this standard shall participate in inter-laboratory comparison exercises (according to EN 442-2). To balance the dry cooling capacity, the test booth will be heated with a number of electrically heated dry cooling load simulators which are positioned on the floor of the test booth. To obtain reproducible results, the simulators shall be arranged according to 4.2. 4.2 Test booth The test is carried out in a test booth according to EN 442-2. In deviation from these definitions the surfaces, floor and ceiling of the test booth shall be insulated in such a way as that the average heat flow in those surfaces is lower than 0,40 W/m² during the test. This heat flow shall be determined by preliminary calibration tests of the booth or by calculations. In deviation from EN 442-2, the reference air temperature shall be 28 °C ± 0,5 K during the measurement. The temperature of the metal surfaces under the insulation of the walls, floor and ceiling of the test booth shall be regulated and be maintained at a value, which is necessary to guarantee a max. temperature difference between these surfaces and the reference air temperature of less than 1,0 K. The radiant emissivity of the surface of the insulation shall be at least 0,9. The test booth will be heated with 10 electrically heated dry cooling load simulators (see Figure 1), which are positioned on the floor of the test booth. The dimension of "a" in Figure 1 depends on the thickness of the inner wall insulation. The output of each simulator shall not exceed 180 W and shall be continually variable. The housing of the simulators consists of pa
