This European Standard supersedes EN 85:1980. This European Standard shall be given th

16、e 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of an identical text or by endorsement, at the latest by February 2000, and conflicting national standards shall be withdrawn at the latest by February 2000.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 Internal Regulations, the national standards organizations

17、 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 and the United Kingdom. This standard is one of a ser

18、ies of standards for doors. This standard has been prepared taking into account ISO 8271 and EN 85.Page 3 EN 950:1999 BSI 12-1999 1 Scope This standard applies to all door leaves. The standard specifies the method to be used to determine the damage caused to a door leaf by the impact of a hard body.

19、 NOTE Such impacts, that might reasonably be expected from contact with small objects or parts of larger objects such as corners on furniture or footwear, can produce local surface failures affecting both strength and appearance. The kind of damage caused by impact can vary with the material used in

20、 the door construction. 2 Apparatus 2.1 Supports Rigid supports, to support the longer edges of the door leaf in a stable manner, when mounted horizontally. 2.2 Impact Equipment A (50 1) mm diameter steel ball, of known weight, and appropriate release tower. 2.3 Measuring equipment A dial or digital

21、 gauge, accurate to 0,01 mm mounted at the centre of a 50 mm long and 12 mm wide reference bar. A steel ruler, accurate to 0,5 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 % relative humidity. 4 Proce

22、dure Mount the door leaf horizontally, with rigid supports under the long edges resting on a solid base. Select one of the four aiming patterns shown in Figure 1 such that the theoretically weakest point is included, and mark the 15 impact points on the surface of the door leaf. Any glazed area shal

23、l be omitted from the test, thereby reducing the number of impact points. Impact points in the topmost row or rows of the aiming pattern shall also be omitted where the height of the door leaf is less than 2 000 mm. The test area is not extended where the height is more than 2 000 mm. NOTE 1 To faci

24、litate the setting out of the aiming pattern, templates can be made for standard sized door leaves in accordance with Figure 1. Holes of approximately 8 mm diameter are drilled in the centres of the numbered rectangles so that a marker pen can be used to indicate the selected aiming pattern onto the

25、 face of the door leaf. Position the release tower vertically over each of the impact points in turn, and drop the steel ball from a height, measured from its underside to the surface of the door leaf, which corresponds to the required impact energy. Where a permanent imprint is left by any impact,

26、after 30 min measure the maximum depth of the indentation to the nearest 0,1 mm, the maximum diameter of the indentation to the nearest 1,0 mm and the maximum diameter of the cracking area to the nearest 1,0 mm. NOTE 2 Where impacts occur at points where the surface is uneven, e.g. at mouldings, a m

27、ore general assessment of damage is permitted. Repeat the procedure for the other face of the door leaf only if the door construction is not symmetrical. 5 Expression of results Record: the measurement of indentation depth and diameter, and the diameter of cracking at each impact point; calculation

28、of the mean values and the coefficient of variation of the depths of indentations; calculation of the mean values and the coefficient of variation of the diameters of cracks. 6 Test report The test report shall contain the following information: a) reference to this standard; b) all necessary detail

29、s to identify the door leaf; c) all relevant details concerning the type, specified dimensions, materials, form and construction of the door leaf; d) position and size of any glazed areas omitted from the test; e) laboratory storage and testing conditions; f) the number and position of impact points

30、 used; g) the impact energy in joules applied in the test; h) the results expressed as in clause 5; i) the nature of any damage; j) name of testing laboratory. k) date of test.Page 4 EN 950:1999 BSI 12-1999 1 Width of door: 10 columns 2 Total of 15 rows 3 Bottom of door 4 Main area 10 Equal division
