The UK participation in its preparation was entrusted by Technical Committee B/538, Doors, windows, shutters, hardware and curtain walling, to Subcommittee B/538/2, Doors,
5、 which has the responsibility to: aid enquirers to understand the text; present to the responsible European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the U
6、K. A list of organizations represented on this subcommittee can be obtained on request to its secretary. This British Standard forms part of a package of standards on doors which will not become fully effective until all standards in the package have been published and any superseded standards have
7、been withdrawn. The date of withdrawal for national standards will be agreed within CEN and will be notified. Cross-references The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entit
8、led International Standards Correspondence Index, or by using the Find facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance w
9、ith a British Standard does not of itself confer immunity from legal obligations.

16、12-1999 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 supersedes EN 24:1974. This European Standard shall be given the status of a national standard
17、, either by publication of an identical text or by endorsement, at the latest by February 2000, and conflicting national standards shall be withdrawn at the latest by February 2000.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
18、 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 United Kingdom. This draft standard is one of a series of standards for door
19、s. This standard has been prepared taking into account EN 24:1974 and prEN 224, and supersedes both.

20、leaves. The standard specifies the method to be used to measure the deviations in general and local flatness of door leaves. 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 equ
21、ipment for general flatness A vertically mounted rigid frame, on which is attached four reference points forming a rectangular 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, accur
22、ate to 0,01 mm, or feeler gauges. 2.2 Measurement equipment for local flatness A dial or digital gauge, accurate to 0,01 mm mounted at the centre of a 200 mm long straight reference bar. NOTEFor non-laboratory testing (e.g. on site) it is acceptable to use a 200 mm long straight reference bar and fe
23、eler gauges. 3 Test specimens Test specimens shall be stored and tested in a non-destructive environment within the ranges of 15 8C to 30 8C 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
24、 each corner of the door leaf, when mounted with its long edges horizontal. Place the door leaf vertically on a long edge against 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
25、 the fourth corner of the reference plane, to the nearest 0,1 mm. 4.2 General flatness measurement of bending With the door leaf 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 deviatio
26、n of the face of the door leaf from the reference bar, to the nearest 0,1mm. Repeat the procedure for the other edges of the 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 visuall
27、y apparent deviations from local flatness on the face of the door leaf, to the nearest 0,05 mm. Repeat the procedure for the other face of the door leaf. NOTEThe test may be carried out with the door leaf in the horizontal or vertical plane. 5 Expression of results Record: the measured value of twis
28、t and maximum deviations in bending for each edge of the door leaf; the position and measured value of any apparent deviations 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 deta
29、ils to identify the door leaf; c) all relevant details concerning the type, specified dimensions, materials, form and construction 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.
