14、retariat of which is held by AFNOR. It is the first method of a series applicable to doors. Work on it was undertaken in June1971 by the group of experts EG3 “Door tests” created in February1971 by the working group, and the method was accepted in1972 by CEN/WG33. This European Standard was adopted
15、by CEN on30 December1974, on the strength of its acceptance by the following member countries: Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, Netherlands, Norway, Spain, Switzerland and United Kingdom.

17、applied to all doors which are nominally flat and rigid. 3 Definition For the purpose of the present standard the concept of general flatness is limited to that of the coincidence of the edges of a face of a door leaf with a reference plane. 4 Principle of the method The measurement of the defects o
18、f general flatness of a door leaf consists in measuring on one face its twist as well as the longitudinal and transverse bending close to the edges. 5 Operating method The door leaf is mounted vertically so that there is no external restraint. 5.1 Measurement of twist. The measurement of twist is ca
19、rried out on one face of the leaf. Any three corners of this face determine a plane of reference. The deviation of the fourth corner is measured with respect to this plane. The measuring points shall not be more than20mm from the edges. 5.2 Measurement of bending. The measurement of bending(s) is ca
20、rried out on one of the faces of the door leaf with respect to straight lines parallel to each edge and located20mm or less from each one. Measure the distance from the face to the straight lines. 6 Accuracy of measurement The twist and bending(s) are to be measured with a maximum uncertainty of 0.5
21、mm. 7 Statement of results The results are to be expressed to the nearest millimetre, 0.5mm being rounded down.4 blankBS 5277:1976 BSI 03-1999 National Appendix A The United Kingdom participation in the preparation of this European Standard came under the authority of the Building Divisional Council
