17、easure the dimensions and the defects of squareness of door leaves. 2 Field of application This standard can be applied to all doors which are nominally flat and rigid. 3 Principle of the method The measurement of dimensions and of the defects of squareness of a door leaf consist in taking: 4 Operat
18、ing method 4.1 Measurement of height. The height is measured along the lines aa and bb (see Figure 1) parallel to and not more than20mm from the two longitudinal edges. 4.2 Measurement of width. The width is measured along the lines cc and dd (see Figure 1) parallel to and not more than20mm from the
19、 transverse edges. 4.3 Measurement of thickness. The thickness is measured at6points located approximately20mm from the edges and at the positions indicated on Figure 1. 4.4 Measurement of defects of squareness. The deviation from squareness of adjacent edges of the door leaf is determined at all fo
20、urs corners of the door leaf with a square with arms500mm long. 5 Accuracy of measurement The height and width are to be measured with a maximum uncertainty of 0.5mm. The thickness and deviation from squareness are to be measured with a maximum uncertainty of 0.1mm. 6 Statement of results The result
21、s of all the measurements are to be noted in the report. The height and width are to be rounded to the nearest millimetre. The thickness and deviation from squareness are to be expressed in millimetres to one place of decimals. a) at one face, measurements of height and width; b) at the indicated po
22、ints, measurements of thickness; c) at the four corners, measurements of deviation from squareness; Figure 1 Door leaf measurementsblankBS5278:1976 BSI 03-1999 National appendix A The United Kingdom participation in the preparation of this European Standard came under the authority of the Building D
