This European Standard supersedes EN
16、 129:1984. 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of an identical text or by endorsement, at the latest by February 2000, and conflicting national standards shall be withdrawn at the latest by February 2000. According to the CEN/CENELEC Interna
17、l 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, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland an
18、d the United Kingdom. This standard is one of a series of standards for doors. This standard has been prepared taking into account ISO 9381 and EN 129 and supersedes EN 129.Page 3 EN 948:1999 BSI 12-1999 Introduction For manufacturers of door leaves whose products are not sold as part of a doorset,
19、provision is made for claiming compliance with the relevant requirements by the testing of such door leaves in a typical frame. Nevertheless, the fact that a particular door leaf meets with the relevant requirements in this way does not necessarily mean that a door assembly incorporating that door l
20、eaf will meet the requirements. 1 Scope This European Standard applies to all vertically hinged or pivoted doors. The standard specifies the method to be used to determine the permanent deformation caused when static stress in torsion is applied to an open door leaf fixed in its own door frame as pa
21、rt of a doorset. NOTE Such torsional stresses that might reasonably be expected, such as in attempts to free a door which sticks, should neither damage nor impair the performance of a door. The method may also be used in respect of a door leaf submitted for test in a frame which the manufacturer con
22、siders appropriate to and typical for the intended utilization. 2 Apparatus 2.1 Test surround The surround in which the test specimen is tested, which shall be sufficiently rigid to withstand the test load without deflecting to an extent likely to influence the test result. 2.2 Loading equipment A s
23、uitable device, with weights or a controlled and calibrated ram, accurate to 2 %. 2.3 Measuring equipment A dial or digital gauge, accurate to 0,01 mm. 3 Test specimens Test specimens shall be stored and tested in a non-destructive environment within the ranges of 158C to 308C and 25 % to 75 % relat
24、ive humidity. Doors which are designed to be glazed, shall be supplied for testing with all glazing carried out in accordance with the door manufacturers specification. 4 Procedure Without any vertical restraint, position the door leaf at an angle of (90 5)8 to the plane of the frame, and fix the to
25、p lockside corner at a point (50 5) mm from each edge of the door leaf. To take up any slack in the hinges, carefully apply a preload of (200 4) N, horizontally and normal to the plane of the leaf at the lower lockside corner, at a point (50 5) mm from each edge of the door leaf. Maintain this load
26、for (60 5) s. Remove the load and after (60 5) s measure, to the nearest 0,1 mm, the location of the lower corner of the door leaf at the loading position (see Figure 1). To the same loading point apply a static load F and maintain for (300 5) s. Measure the maximum deformation under load to the nea
27、rest 0,1 mm. Remove the load and after (180 5) s repeat the measurement at the lower corner of the door leaf. All loads shall be carefully applied and removed in maximum 100 N, accurate to 2 % increments and over a minimum of 1 s for each increment, or the equivalent rate if continuous, in order to
28、avoid dynamic effects. 5 Expression of results Record: the deformation under load F and the residual deformation of the door leaf as expressed by the difference in the measurements at the lower corner of the door leaf before the application of load F and (180 5) s after the removal of this load. 6 T
29、est report The test report shall contain the following information: a) reference to this European Standard; b) all necessary details to identify the doorset or door leaf; c) all relevant details concerning the type, specified dimensions, materials, form and construction of the doorset or door leaf,
30、including the position of hardware; d) full details of the frame and hardware supplied if the assembly is not a doorset; e) laboratory storage and testing conditions; f) the load F, in newtons, applied in the test; g) the results expressed as in clause 5; h) details of any damage that appeared durin
31、g the test; i) name of testing laboratory; j) date of test.Page 4 EN 948:1999 BSI 12-1999 Dimensions in millimetres Figure 1blankBS EN 948:1999 BSI 389 Chiswick High Road London W4 4AL | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
