DIN EN 13050:2011-09 EN 13050:2011 (E) 4 1 Scope This European Standard defines an additional test method which may be used when assessing the watertightness of curtain walling, both its fi
19、xed and openable parts. It is a supplementary test, not required for classification purposes, and it should be used only when the project specifier has determined its necessity. This European Standard describes how the outside face of a curtain walling specimen should be subjected to a continuous sp
20、ray of water and a turbulent airflow, with continuous pulses of positive air pressure on the outside of the test specimen generated from within the chamber. This European Standard applies to any curtain walling product as defined in EN 13830. 2 Normative references The following referenced documents
21、 are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 13119:2007, Curtain walling - Terminology 3 Terms and definitions For the purpos
22、es of this document, the terms and definitions given in EN 13119:2007 and the following apply. 3.1 test pressure difference between the static air pressures on the outside and inside faces of the test specimen, which is expressed in Pascals (Pa) 3.2 positive test pressure when the static air pressur
23、e is greater on the outside face of the test specimen than on the inside face 3.3 watertightness ability of the curtain walling specimen to resist water leakage 3.4 water leakage penetration of water that continuously or repeatedly wet parts of : 1) the inside face of the specimen 2) any parts of th
24、e specimen not intended to be wetted as part of the system of water drainage to the outside 4 Principle The application of a constant and specified quantity of water in a spray combined with a specified turbulent airflow and continuous regular pulses of positive test pressure, on to the outside face
25、 of the specimen, while inspecting for water leakage. DIN EN 13050:2011-09 EN 13050:2011 (E) 5 5 Apparatus 5.1 A chamber with an opening into which the test specimen can be fitted. This chamber shall be of sufficient strength and rigidity to withstand the test pressures likely to be imposed during t
26、he tests. It shall not deflect under test pressure to any extent which would affect the performance of the test specimen (Figure 2). Adequately representative structural supports shall be provided to which the specimen shall be attached in accordance with the conditions of use in the works (see also
27、 Clause 6). 5.2 A means for applying controlled positive test pressures to the specimen arranged such that the air does not impinge directly on the specimen with any significant velocity. 5.3 A means by which rapidly controlled changes of test pressure may be produced within defined limits. 5.4 A me
28、ans of measuring the applied test pressures, steady or fluctuation, calibrated within an accuracy of 5 %. 5.5 An adjustable device for spraying water at a minimum of 2 l/mmin so that a constant and continuous film is applied to the outside surface of the specimen. The water spraying device shall hav
29、e nozzles spaced on a regular grid and at a uniform distance from the outside surface of the specimen (see Figures 3 and 4). The local mains water supply will be an acceptable source providing it is clean enough to allow the spray nozzles to function properly throughout the test. The nozzles shall i
30、nclude the following features: Circular full cone spray; Spray angle minimum 90 to maximum 120; Working pressure range two to three bars according to the manufacturers specification. 5.6 A means of measuring the total amount of water supplied within an accuracy of 10 %. 5.7 A drain for the sprayed w
31、ater which will not interfere with the drainage of the specimen frame. 5.8 A mobile wind generator for applying a controlled turbulent airflow to all points on the outside surface of the specimen. The turbulent airflow shall be generated by a variable speed axial fan fixed to a 600 mm diameter rigid
32、 duct which directs the airflow around a 90 bend onto the outside surface of the specimen (see Figure 5). The bend in the duct shall have an inside radius of 300 mm 5 mm and the straight length of duct after the bend shall be 300 mm 10 mm. The fan shall be capable of generating an airflow with the f
33、ollowing features, measured 20 mm from the end of the duct and not more than 300 mm from its central horizontal axis: 3) A minimum velocity of not less than 30 m/s along the central horizontal axis. 4) A minimum velocity of not less than 20 m/s over 75 % of the measurement area. 5) A minimum velocit
34、y of not less than 8 m/s at any point within the measurement area. The axis of the airflow from the duct shall be horizontal and normal to the outside surface of the specimen with the end of the duct 650 mm, 50 mm, from the specimen. The wind generator shall be mounted on a device that provides cont
35、rolled movement in any direction in a plane DIN EN 13050:2011-09 EN 13050:2011 (E) 6 parallel to the glazing or infill panels without regard for any small inclined sections of the specimen. 6 Test specimen The specimen shall be submitted in a fully operable condition, ready for use. It shall be supp
36、lied in a suitable manner for fixing onto the test chamber. The test specimen shall not be less than two typical units wide and shall be sufficient to provide full loading on at least one typical vertical joint or framing member or both. The specimen shall not obtain additional stiffness from the te
37、st chamber. The height shall be not less than the full distance between the curtain walls point of connection to the building structure. For custom designed curtain walls or special elements, the specimen shall be a size which is adequate to demonstrate its compliance with the specified requirements
38、. All parts of the specimen shall be full size, using the same materials, details, methods of construction and fixing as intended for use in the works. Conditions for connection to the structural support shall simulate those in the works as accurately as possible (see also 5.1). This standard does n
39、ot apply to the perimeter joints between the curtain walling and the test chamber, or to the joints between the curtain walling and the building construction. 7 Specimen preparation No further preparations are necessary other than those already carried out for the preceding air permeability, waterti
40、ghtness and wind resistance tests. 8 Test Procedure Open and close all openable windows 5 times and finally secure them in the closed position. Calculate the maximum test pressure (Pmax) and the minimum test pressure (Pmin) from the actual, or intended maximum, design wind pressure (Pdesign) for the
41、 certain walling to comply with: For the calculation generally the highest design wind pressure (Pdesign)(positive or negative) shall be taken in account. Pmax= 3 Pmin= 0,375 x Pdesign Apply 3 pulses of positive pressure equal to 500 Pa or 10 % greater than the maximum test pressure (Pmax), whicheve
42、r is greater. The time to increase the pressure up to the maximum value shall be between 1 s and 3 s. Each pulse shall be maintained for at least 3 s. Operate the water sprays with 0 Pa test pressure and adjust the total flow to provide 2 l/m2per minute or the higher flow specified by the manufactur
43、er calculated from the area of the specimen under test. After 15 min of spraying without pressure (if the test subsequently to a watertightness test according to EN 12155 the unpressurized spraying time can be reduced to 5 min) apply positive test pressures in continuous regular pulses with a maximu
44、m value equal to the maximum test pressure (Pmax) and a minimum value equal to 0,33 x Pmax. The duration of each pressure pulse shall be 5 s 1 s. The wind generator shall be positioned so that the distance between the horizontal axis of the duct and the bottom edge of the test specimen are approxima
45、tely 0,30 m. The vertical axis of the wind generator shall be not less then 0,30 m and not more than 0,90 m away from any mullion axis (case 1). If the distance between the axis of the mullions less than 0,6 m each mullion shall be tested separately (case 2). If the distance between the vertical axi
46、s of the mullions more than 1,80 m, than as well every mullion shall be tested separately. In this case the vertical axis of the wind generator shall be 0,30 m away from the axis of the tested mullion (case 3) see Figure 1.

Move the wi
48、nd generator upwards at 2,5 m/min, 0,5 m/min, until the central horizontal axis from the duct is 0,3 m from the top of the specimen (see cases 1 to 3). Return the wind generator as rapidly as possible to the starting position near the bottom of the specimen. Make a second upward pass with the wind g
49、enerator as before and return it to the starting position. Traverse the wind generator across the specimen so that the central horizontal axis of the duct is midway between the next pair of mullions and make two upward passes with the wind generator as before. Repeat this process until the whole of the specimen has been covered. Constantly inspect the inside surfaces of the specimen for water leakage throughout the spraying period. Record the details of any water leaks that are o
