15、 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 supersedes EN 24:1974. This European Standard shall be given the status of a national standard, either by publ

16、ication of an identical text or by endorsement, at the latest by February 2000, and conflicting national standards shall be withdrawn at the latest by February 2000. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implem

17、ent 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 draft standard is one of a series of standards for doors. This standard

18、 has been prepared taking into account EN 24:1974 and prEN 224, and supersedes both.Page 3 EN 952:1999 BSI 12-1999 1 Scope This standard can be applied to all rectangular door leaves. The standard specifies the method to be used to measure the deviations in general and local flatness of door leaves.

19、 In this standard the concept of local flatness deviation is limited to defects considered to be prejudicial to the appearance of the door leaf. 2 Apparatus 2.1 Measurement equipment for general flatness A vertically mounted rigid frame, on which is attached four reference points forming a rectangul

20、ar reference plane, appropriate to the size of door leaf to be tested. A straight reference bar, capable of spanning the height of the door leaf. A dial or digital gauge, accurate to 0,01 mm, or feeler gauges. 2.2 Measurement equipment for local flatness A dial or digital gauge, accurate to 0,01 mm

21、mounted at the centre of a 200 mm long straight reference bar. NOTE For non-laboratory testing (e.g. on site) it is acceptable to use a 200 mm long straight reference bar and feeler gauges. 3 Test specimens Test specimens shall be stored and tested in a non-destructive environment within the ranges

22、of 158C to 308C and 25 % to 75 % relative humidity. 4 Procedure 4.1 General flatness measurement of twist Position the reference points to occur (20 5) mm in from the edges of each corner of the door leaf, when mounted with its long edges horizontal. Place the door leaf vertically on a long edge aga

23、inst the reference plane so that without restraint it makes contact with three corners of the reference plane. Measure the deviation of the fourth corner of the door leaf from the fourth corner of the reference plane, to the nearest 0,1 mm. 4.2 General flatness measurement of bending With the door l

24、eaf mounted vertically, position the straight reference bar along the face of the door leaf, parallel to and not more than 20 mm in from one edge. Measure the maximum deviation of the face of the door leaf from the reference bar, to the nearest 0,1 mm. Repeat the procedure for the other edges of the

25、 door leaf. 4.3 Local flatness measurement The door leaf is to be supported without restraint. With the 200 mm long reference bar and dial or digital gauge, measure any visually apparent deviations from local flatness on the face of the door leaf, to the nearest 0,05 mm. Repeat the procedure for the

26、 other face of the door leaf. NOTE The test may be carried out with the door leaf in the horizontal or vertical plane. 5 Expression of results Record: the measured value of twist and maximum deviations in bending for each edge of the door leaf; the position and measured value of any apparent deviati

27、ons in local flatness for each face of the door leaf. 6 Test report The test report shall contain the following information: a) reference to this standard; b) all necessary details to identify the door leaf; c) all relevant details concerning the type, specified dimensions, materials, form and const

28、ruction of the door leaf; d) laboratory storage and testing conditions; e) the results expressed as in clause 5; f) name of testing laboratory; g) date of test.BS EN 952:1999 BSI 389 Chiswick High Road London W4 4AL | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
