33、cial test corner according to FigureZ201 and made of dull black-paintedplywood approximately20 mm thick. All measures given in the figure are internal. The wall A can bepositioned at different distances fr om the far end of the special test corner. For the tests the special test corner is placed in
34、a test corner, as described in EN60335-1, with wallBand the far end facing the walls of the test corner. The test corner as described in EN 60335-1 shall be atleast 470 mm wide, 760 mm deep and 470 mm high. NOTE WallB of the special testcorner, as well as its bottom ,can be open to facilitate access
35、 before and after test. During test thespecial testcorner is placed in the test corner in such a way, that it becomes closed by the walls and floor of the testcorner, leavingonly the opening towards wall A open.The cab heater is placed in the special test corner in the most unfavourable position acc
36、ording to the manufacturers instructions, if it will fit into the special test corner, and with the distance L = 0 mm. Theshortest distance to combustible material shall however not be less than stated in the manufacturersinstructions and the wall A can be moved to increase L to a maximum distance L
37、 = 220 mm. If the manufacturer has not supplied any instructions for the placing of the cab heater or if the heatercannot fit in the special test corner, the cab heater is placed in the most unfavourable position on the floor of the special test corner. Heaters containing PTC heating elements are pl
38、aced a way from the wallsif this will lead to higher temperatures.

44、to the test wall is measured as the shortest distance between the wall and the outletfireguard. The heater is covered, totally or partially, with a piece of cloth and is tested as specified in 19.1.The piece of cloth used shall have a thickness of 25 mm and a mass of (4,0 0,4) kg/m. It shall b e pla
