31、g the test (see Figure 1). This can be done either by the back wall itself or by a flat cooling surface (emission coefficient has to be at least 0,9) covering the whole width and height of the room placed in front of the back wall of the closed test room in accordance with EN 442-2. The space betwee
32、n the cooling plate and the booth back wall shall be closed off to prevent air from flowing through. Dimensions in metres Key a cooling surface, temperature 16 C 0,5 K 1 reference air temperature trFigure 1 Positioning of the cooling surface in the test room The trench convector with its associated
33、trench and the intended covering is installed in the booth floor in front of this cooling surface, flush with the finished floor level, in accordance with the manufacturers instructions. Unless other dimensions have been given by the manufacturer, the distance between the trench and the cooled back
34、wall shall be 0,05 m (see Figure 2). For the purposes of the test, the trench in itself is covered with a thermal insulation shown in Figure 2 which has a thermal resistance of at least R =1,0 m2K/W. If the floor of the test booth is cooled then the floor has to have a thermal resistance of at least
35、 R =2,5 m2K/W. If the floor of the test booth is not cooled then there is no requirement for such a thermal resistance.

In the case of trench convectors without fan(s) the convector length to be tested (finned length) should be 2 m; if that length is not available, th
38、e next available length 2 m shall be tested. The length of the sample under test shall be adapted if the requirements for either the minimum or maximum thermal output according to 4.2.1 are not fulfilled. In the case of finned tube convectors, a finned length of 1 m is assumed as the module. In the
39、case of trench convectors with fan(s) the convector length to be tested (finned length) should be at least 1 m, if that length is not available, the next available length 1 m shall be tested. The length of the sample under test shall be adapted if the requirements for either the minimum or maximum t

The convector as such is installed in the trench, applying the manufacturers fixing material, spacers, covering, etc. and following the manufacturers instructions. The testing application shall be accompanied by drawings showing the dimensions of t
41、he trench and the convector as well as the convectors positioning in the trench and the design of the covering. 4.1.2 Fan assisted radiators and wall mounted convectors Radiators and wall mounted convectors shall be installed according to EN 442-2. Unless other dimensions have been given by the manu
42、facturer, the distance between the radiator / convector and the back wall of the test room shall be 0,05 m, the distance between the radiator / convector and the floor of the test room shall be 0,11 m. If it is possible to allocate the models to a certain type with a characteristic size (e. g. heigh
43、t) whose changes point to the fact that a continuous dependence of the thermal output can be expected, the smallest and the largest sizes each and so many intermediate sizes shall be tested that a ratio of 1:2 is not exceeded. In the case of radiators / convectors the length of the sample to be test
44、ed (in case of convectors: finned length) should be 1 m, if that length is not available, the next available length 1 m shall be tested.

The testing application shall be accompanied by drawings showing the dimensions o

The standard heating out
47、put is to be determined at different water flow rates with the following limitations: Thermal output: min. 200 W; max. 3 500 W (according at standard conditions). 4.2.2 Determination of the thermal output 4.2.2.1 General The procedure of the test and the determination of the thermal output are perfo
