18、 a heating element (fitted opposite the burner). It shall be set up in an enclosedspace (test room).3.2 Fire chamberThe dimensions of the fire chamber and its floor, ceiling, walls and openings shall be as shown in figure 1. Itswalls shall be made of A353) refractory bricks having a density of 1,9 k
19、g/dm3to 2,1 kg/dm3, fitted in a steelframework. The ceiling and the floor shall be of refractory concrete having a density of 2 kg/dm3to 2,2 kg/dm3.The outside of the furnace may be clad with sheet steel about 2 mm thick, with thermal insulation beingoptionally provided between the furnace wall and
20、the cladding.There shall no be more than one opening for inserting a specimen in each longitudinal wall and in the ceiling.No more than two closable inspection openings, each having a maximum clear area of 100 cm2, may beprovided. The flue gas outlet shall be designed to produce a gauge pressure in
21、the fire chamber of up to 12 Paafter the first five minutes of testing.1) Issued by Deutsches Institut fr Bautechnik, Kolonnenstr. 30 L, 10829 Berlin, Germany.2) Issued by Verlag Stahleisen mbH, P.O.
