11、his European Standard was approved by CEN on 2 November 1999. CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical refe

12、rences concerning such national standards may be obtained on application to the Central Secretariat or to any CEN member. This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member i

13、nto its own language and notified to the Central Secretariat has the same status as the official versions. CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal,

14、 Spain, Sweden, Switzerland and United Kingdom.Page 2 EN 1933:1998 BSI 03-1999 Foreword This European Standard has been prepared by Technical Committee CEN/TC 33, Doors, windows, shutters and building hardware, the Secretariat of which is held by AFNOR. This European Standard shall be given the stat

15、us 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of an identical text or by endorsement, at the latest by May 1999, and conflicting national standards shall be withdrawn at the latest by May 1999.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 package of standards dealing with blinds and shutters defined in prEN 12216. The test m

16、ethod is linked to performance requirements for exterior blinds specified in a standard in preparation (WI 00033143, Exterior blinds Requirements and classification). According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to imple

17、ment this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

This standard is applicable to exterior blinds forming an overhang when they are

20、 in extended position. These are: folding arm blind; trellis arm blind; adjustable or fixed Dutch awning. 2 Normative references This European Standard incorporates by dated or undated references, provisions from other publications. These normative references are cited at the appropriate places in t

21、he text and the publications 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

22、to applies. prEN 12216, Terminology and definitions for blinds and shutters. prEN 12046, Shutters and blinds Measurement of operating force Test methods. 3 Definitions For the purposes of this standard, the definitions given in prEN 12216 and in the standard in preparation (WI 00033143) apply togeth

23、er with the following. 3.1 water pocket 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 expre

24、ssed in degrees (see Figure 1) Does not apply to Dutch awning. 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 projection distance AL measured horizontally with the blind in the fully extended

25、position, between the wall and the front profile 3.5 width width L of the fabric, or the frame width for a Dutch awning Figure 1 Water pocket caused by precipation (rain) for folding arm blind 4 Test conditions The extended blind is sprayed with a controlled amount of water and its mechanical perfor

26、mance is tested under the action of a weight of retained water. 5 Equipment 5.1 Test rig The test rig is made up of a rigid support in which the blind is installed using its fixtures according to the installation instruction. For trellis arm and folding arm blinds, the angle below the horizontal is

27、148 (slope 25%). 5.2 Watering spray pipe The shower of water is obtained using a 1 in (38 mm diameter) row pierced with holes of 2,0 mm 0 +0,5 diameter spaced at regular intervals of 50 mm 1m m and positioned above the blind as shown in Figures 2a) and 2b). A uniform spraying requires a two point en

28、try of water to the spray pipe equidistant from the middle. The distance between the two entry points is between one-third and one-half of the total pipe length. The pipe length shall be at least the width of the awning. If the awning width is less, it shall be positioned in the middle of the water

29、spray pipe. The extra holes shall be sealed. 5.3 Measuring equipment An installation capable of measuring the water flow to an accuracy of 5%.Page 4 EN 1933:1998 BSI 03-1999 Dimensions in millimetres a) Projecting and trellis arm blinds b) Dutch awning Figure 2 Positioning of watering spray pipe and

30、 holesPage 5 EN 1933:1998 BSI 03-1999 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 of awnings receive the same class. 6.2 Dutch awning Use the maximum dimensions (wid

31、th and projection) of the manufacturers specification for the maximum distance between the arms. Smaller sizes of awnings receive the same class. 7 Tests For adjustable blinds, measure and record the operating force P i , according to prEN 12046, prior to the test. With the flow of water set for the

32、 class being tested, the spraying is maintained for 1 h. In the case of class 1: 17 l/(m 2 h), for class 2: 56 l/(m 2 h) (surface = L3 AL). The test method described also applies to test the correct functioning of the drainage holes where they exist. Once the showering has stopped, the water has dra

33、ined and the fabric dried for 30 min, measure the operating force P e as described in prEN 12046. 8 Expression of results Failure, yes/no. Record any deterioration. For adjustable blinds, record the value of the operating force P e (after the fabric has dried) and the performance variation: V = 100

34、in % 21 P e P i where P i is the operating force before test; P e is the operating force after test; V is the variation as a percentage. 9 Test report The report shall cover the following: a) conformity of the test product with the manufacturers technical instructions including dimensions; b) positi

35、oning of the operating mechanism used relative to the types of operation available, possible options and their technical limits; c) information necessary to identify the product; d) information as to type, the dimensions, materials, form and assembly, means of evacuating the water, instruction relat

36、ing to the projection; e) information on accessories, fixings, operation mechanism; f) dimensional limits relative to width, drop, height, surface area and slope; g) dimensions of the product under test; h) types of test carried out; i) types and weight per square metre of the cover; j) height of th

37、e water column supported by the new fabric (stated by the manufacturer); k) number and position of drainage holes (eyelets); l) diameter of the eyelets; m) adjustable blinds the values of P i and P e of the operating force and the percentage variation V in performance; n) name of the test laboratory

38、 (firm or laboratory), name of person responsible for the test; o) date of the test; p) reference of the standard prevailing.BSI 389 Chiswick High Road London W4 4AL | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
