This European Standard replaces EN 25:1975. This European Standard

16、shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 1999, and conflicting national standards shall be withdrawn at the latest by December 1999. This standard is one of a series of standards for doors. The test method r

17、elates to performance requirements to be published in EN 1529. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece

18、, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.Page 3 EN 951:1998 BSI 05-1999 1 Scope This European Standard applies to all rectangular door leaves and the measurable parameters of doors of other shapes. This standard specifies

19、 the method to be used to measure the dimensions of height, width and thickness, and defects of squareness of door leaves. 2 Apparatus 2.1 Measurement instrument for height and width, steel measuring tape, or similar measuring instrument, accurate to 0,5 mm. 2.2 Measurement instrument for thickness,

20、 micrometer, or similar measuring instrument accurate to 0,01 mm. 2.3 Measurement instrument for squareness, a metal square having two arms with inside reference dimensions of (500 1) mm. The right angle between the arms shall be accurate to 0,1 mm in 500 mm. The square shall incorporate a dial or d

21、igital gauge accurate to 0,1 mm mounted at the 500 mm reference point of one arm (see Figure 1). NOTE An additional block and feeler gauges may be used in place of the dial or digital gauge. 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. Doors which are designed to be glazed, shall be supplied for testing with all glazing carried out in accordance with the door manufacturers specifications. 4 Procedure 4.1 Height and width measurement Measure, to the nearest 1 mm, the height and w

23、idth of each door leaf along lines a-a, b-b, c-c, d-d parallel to, and (20 5) mm from, each edge respectively (see Figure 2). NOTE In the case of a door leaf with rebated edges, the dimensions of height or width should be measured to the inner edges of the rebates. 4.2 Thickness measurement Measure

24、the thickness at 6 points located (20 5) mm from the edges and at the positions indicated in Figure 2, to the nearest 0,1 mm. NOTE If a measuring point occurs where the thickness is not representative of the doors, e.g. because of surface profiles, local adjustment of the measurement position is per

25、mitted. 4.3 Squareness measurement Measure any deviation from squareness of the door leaf at all four corners to the nearest 0,1 mm. 5 Expression of results Record: height and width measurements and maximum deviations in relation to the specified dimensions; thickness measurements and maximum deviat

26、ion in relation to the specified dimension; the four measured values of deviation from squareness. 6 Test report The test report shall contain the following information: a) reference to this European Standard; b) all necessary details to identify the door leaf; c) all relevant details concerning the

27、 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.Page 4 EN 951:1998 BSI 05-1999 Dimensions in millimetres 1 reference square to calibra
