13、 secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 1999, and conflicting national standards shall be withdrawn at the latest by May 1999. It is part of a p
14、ackage of standards dealing with blinds and shutters defined in prEN 12216. The test method is linked to performance requirements for exterior blinds specified in a standard in preparation (Wi 000331 43 : “Exterior blinds - Requirements and classification”). According to the CENCENELEC Internat Regu
15、lations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the
16、United Kingdom. 1. SCOPE This European Standard specifies a test method for determining the ability of exterior blinds to resist loads caused by the retention of rain water by the fabric. This Standard is applicable to exterior blinds forming an overhang when they are in extended position. These are
17、 : - folding arm blind - trellis arm blind - adjustable or fixed Dutch awning. 2. NORMATIVE REFERENCE This European Standard incorporates by dated or undated references, provisions from other publications. These normative references are cited at the appropriate places in the text and the publication
18、s are listed hereafter. For dated references, subsequent amendments to, or revisions, of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies. prEN 1221 6 Ter

DEFINITIONS For the purposes of this Standard, the definitions given in prEN 12216 and in the standard in preparation (Wi 00033143) apply together with the following : P
20、age 4 EN 1933:1998 3.1 Water pocket A reservoir formed when, under the action of precipitation, the fabric of the external blind, in extended position, retains and accumulates water and suffers progressive deformation (see figure 1). 3.2 Slope Angle of the fabric in relation to the horizontal expres
21、sed in degrees (see figure 1). Does not apply to Dutch awning. Figure 1 : Water pocket caused by precipation (rain) for folding arm blind 3.3 Drainage holes Holes made in the fabric at carefully chosen points allowing the drainage of water retained by the fabric before water pockets form. 3.4 Projec
22、tion Distance AL measured horizontally with the blind in the fully extended position, between the wall and the front profile. 3.5 Width Width L of the fabric, or the frame width for a Dutch awning. STD-CEN EN 1133-ENGL 1798 E 34U4587 0382559 375 Page 5 EN 1933:1998 4 TEST CONDITIONS The extended bli
23、nd is sprayed with a controlled amount of water and its mechanical performance is tested under the action of a weight of retained water. 5 EQUIPMENT 5.1 Test rig The test rig is made up of rigid support in which the blind is installed using its fixtures according to the installation instruction. For
24、 trellis arm and folding arm blinds, the angle below the horizontal is 14“ (slope 25%). 5.2 Watering spray pipe The shower of water is obtained using a row of 1W (38 mm diameter) pierced with holes of 2,O 0. mm diameter spaced at regular intervals of 50 mm f 1 mm and positioned above the blind as sh
25、own in figures 2a) and 2b). A uniform spraying requires a two point entry of water to the spray pipe equidistant from the middle. The distance between the two entry points is between one third and one hat of the total pipe length. The pipe length shall be at least the width of the awning. If the awn
26、ing width is less, it shall be positioned in the middle of the water spray pipe. The extra holes shall be sealed. Dimensions in millimetres 2a) : Projecting and trellis arm blinds Page 6 EN 1933:1998 Dimensions in millimetres 2b) : Dutch awning Figure 2 : Positioning of watering spray pipe and holes
27、 5.3 Measuring equipment An installation capable of measuring the water flow to an accuracy of f5%. 6 TEST SAMPLE DIMENSIONS 6.1 Folding and trellis arm blinds Use the maximum dimensions (width and projection) of the manufacturers specification for a pair of arms. Smaller sizes awnings receive the s
28、ame class. 6.2 Dutch awning Use the maximum dimensions (width and projection) of the manufacturers specification for the maximum distance between the arms. Smaller sizes awnings receive the same class. 7 TESTS For adjustable blinds, measure and record the operating force Pi, according to prEN 12046,
29、 prior to the test. With the flow of water set for the class being tested, the spraying is maintained for 1 h. In the case of class 1 : 17 l/m2/h, for class 2 : 56 m2/h (surface = L x AL). The test method described also applies to test the correct functioning of the drainage holes where they exist.
30、* Once the showering has stopped, the water has drained and the fabric dried for 30 mn, measure the operating force Pe as described in prEN 12046. Page 7 EN 1933:1998 8 EXPRESSION OF RESULTS - Failure, yes/no - Record any deterioration - for adjustable blinds, record the value of the operating force
31、 Pe (after the fabric has dried) and the performance variation : Pe Pl v = 100(-1) in % -dhere : Pi is the operatrng force before test Pe is the operating force aiter test V is the variation as a percentage 9 TESTREPORT The report shall cover the following : a) Conformity of the test product with th
32、e manufacturers technical instructions including dimensions, b) Positionning of the operating mechanism used relative to the types of operation available, posible options and their technical limits, c) Infomation necessary to identify the product, d) Information as to type, the dimensions, materials
33、, form and assembly, means of evacuating the water, instruction relating to the projection, e) Informations on accessories, fixings, operation mechanism, f) Dimensional limits relative ot width, drop, height, surface area and slope, g) Dimensions of the product under test, h) Types of test carried o
34、ut, ,i) Types and weight per m2 of the cover, j) Height of the water column supported by the new fabric (stated by the manufacturer), k) Number and position of drainage holes (eyelets), i) Diameter of the eyelets, m) Adjustable blinds -the values of Pi and Pe of the operating force and the percentage variation V in performance, n) Name of the test laboratory (firm or laboratory), name of person responsible for the test, o) Date of the test, p) Reference of the Standard prevailing.
