28、 test specimen where water does not drain to the outside in a controlled way Note 1 to entry: Continuous wetting could be described as an uninterrupted sequence of water, e.g. thin line of water, repeated wetting could be described as frequent intervals of water, e.g. more than one drop of water. 3.

29、5 limit of watertightness maximum test pressure Pmaxup to which the test specimen remains watertight under the test conditions for the specified time 4 Principle of test Constant spraying of a specified quantity of water onto the external surface of the test specimen while increments of positive tes

30、t pressure are applied at regular intervals during which details are recorded of test pressure and location of water penetration. 5 Test apparatus 5.1 A chamber with an open side to which the test specimen can be fitted. It shall be constructed so as to be able to withstand the test pressures withou

31、t deflecting to an extent likely to influence the test results. 5.2 Means for applying controlled test pressure to the test specimen. 5.3 Means of producing rapid changes in test pressure, controlled within defined limits. 5.4 Instrument suitable for measuring the quantity of water supplied within a

32、n accuracy of 10 % of the measured value. BS EN 1027:2016EN 1027:2016 (E) 6 If several rows of nozzles with different flows are included, the total flow of water has to be checked. It shall be in accordance with 5.6 c). Furthermore the spraying pattern of the lower row of nozzles has to be checked a

33、dditionally. It is recommended to use at least two such instruments. NOTE 1 Accuracy = (the sum of the amount of the error plus the amount of the expanded measurement uncertainty). For values of both error and expanded measurement uncertainty see last calibration certificate of the instrument. NOTE

34、2 For vocabulary of metrology see ISO/IEC Guide 99:2007. 5.5 Means of measuring the test pressure applied across the test specimen, within an accuracy of 5 %. 5.6 A spraying system capable of applying a continuous regularly dispersed film of water, all over the surface likely to be wetted in real ex

35、posure conditions, by means of full circular cone nozzles with the flowing features: a) angle of spray: ( )0- 10120 ; b) pressure working range: 2 bar to 3 bar according to manufacturers specifications; c) nozzle rate: top row (2 0,2) l/min per nozzle, additional rows (1 0,1) l/min per nozzle and (2

36、 0,2) l/min per nozzle (see 6.2.5). 6 Preparation of test specimen 6.1 Set-up of the test specimen The test specimen shall be fixed as intended for use without any twists or bends which may influence the test results. The test specimen shall be fully operable. The surround shall be prepared and inst

37、alled so that any water penetration, including that through the frame joints, shall be readily detectable. The test specimen shall be cleaned and surfaces dry. Ventilation devices, if any, shall be taped over. 6.2 Set-up spraying system (see Figures A.1 to A.6) 6.2.1 General The method of spraying (

38、Method A or Method B) shall be chosen by the manufacturer based on the location of the test specimen in the intended works (shielded or not)A test shall be carried out using only one set up. A template is recommended to set up the spraying system. 6.2.2 Positioning of the line connecting the nozzle

39、tips (the nozzle line) The nozzle line shall be located not more than 150 mm above the topmost horizontal joint line of any moving frame or the glazing line of any fixed glazing, in order to provide complete wetting of the adjacent horizontal frame member(s).The nozzle line shall be located at a dis

40、tance of ( )10 0 250+mm from the external face of the test specimen as defined by the outermost external joint plane of moving parts or the glazing plane of fixed parts. BS EN 1027:2016EN 1027:2016 (E) 7 6.2.3 Positioning relative to test specimen width Nozzles shall be spaced at (400 10) mm along t

41、he axis of the spray bar and the nozzles shall be arranged in order that the lateral distance c“ between the outer edge of the surround and the outermost nozzles shall be greater than 50 mm but not exceeding 250 mm (see Figure A.6). 6.2.4 Direction of nozzle spray The nozzle axis shall lie on a line

42、 ( )2024+ below the horizontal line for test according to Method 1A, and (84 2) for test according to Method 1B (see Figures A.1 and A.2). 6.2.5 Number of nozzle rows 6.2.5.1 For test specimens with a height up to 2,5 m, including e.g. extension profiles and/or shutter boxes (see Figure A.5) a singl

43、e row of nozzles shall be used, with each nozzle spraying, on average, 2 l/min for spraying Method 1A and spraying Method 1B. NOTE The prescribed spraying rates above are appropriate for 2,5 m high test specimen. For smaller test specimen the nozzles spray water beyond the sill, hence the actual flo

44、w on the sprayed area is approximately 2 l/(minm2) when test is carried out according to Method 1A, 1 l/(minm2) when test is carried out according to Method 1B. 6.2.5.2 For test specimens exceeding 2,5 m height (see Figures A.3 and A.4), including e.g. extension profiles and/or shutter boxes (see Fi

45、gure A.5), an upper row of nozzles shall be fixed as described in 6.2.5.1. Additional rows of nozzles shall be fixed at vertical intervals at 1,5 m (within a tolerance of 150 mm) below the top nozzle line. Where any horizontal projection occurs, these additional rows shall be installed at a level su

46、ch that no water is sprayed upwards under the projection. The flow of each nozzle shall be on average 1 l/min for spraying Method 2A, 2 l/min for spraying Method 2B. 6.2.5.3 For test specimens containing one or more horizontal water bars which project more than 50 mm (see Figure A.8) an additional r

47、ow of nozzles, as described in 6.2.5.2, shall be arranged for each water bar as shown in Figure A.2. 6.3 Water characteristics Water temperature shall be between 4 C and 30 C and the water shall be clean enough to ensure that all nozzles spray correctly. 7 Test procedure 7.1 Preliminaries The ambien
