EN 1023-2 Office fwniture - Screens - Part 2: Mechanical safety requirements. 3 Definitions For the purposes of this standard, the following definition applies. 3.1 add-on elements types of biture items to be attached on screens
19、(worktops, shelves, hanging cupboards, lateral pull-out filing drawers .) 4 General test conditions The manufacturer shall indicate in his instruction manual the recommended screen configurations, the method of attachment of components, how to use the screens in combination with the different add-on
20、 elements, as well as the maximum admissible load of each type of screen (load in kg for 1 m of screen width). In case of designs not catered for in the test procedures, cany out the test as far as possible as described and state any deviations in the test report. 4.1 Preliminary preparation Before
21、any of the tests are commenced, the item shall be old enough to ensure that it has developed its full strength. At least four weeks in normal indoor conditions shall have elapsed between manufacture and testing in the case of glued joints in timber and the like. The furniture shall be tested as deli
22、vered. Knock-down furniture shall be assembled according to the instructions supplied with it. If the furniture can be assembled or combined in different ways, the most adverse combination shall be used for each test. Knock-down fittings shall be tightened before testing. For each test, all componen
23、ts shall be in their least favourable position. The tests shall be carried out in normal indoor ambient conditions but, if during a test, the atmosphere temperature is outside the range 15 “C to 25 OC, the maximum and/or minimum temperature shall be recorded in the report. O BSI 08-2000 Page 4 EN 10
24、23-3:2000 4.2 Test equipment The forces in strength tests shall be applied sufficiently slow to ensure that dynamic effects are negligible. Test loads and test forces may be applied by any suitable device because results are not dependent upon the apparatus. Unless otherwise specified, loading pads
25、shall pivot and shall be fixed so that they do not prevent the screen from moving during testing. 4.3 Tolerances Unless otherwise stated: - all forces shall have an accuracy of *5 % of the nominal force; - ail dimensions an accuracy of k1 mm of the nominal dimension; - all masses an accuracy of *l %
26、 of the nominal mass; - the tolerance for position of loading pads shall be 15 mm. 4.4 Test sequence The tests shall be carried out on the same sample and in the order specified in EN 1023-2. 5 Test apparatus 5.1 Floor surface A rigid, horizontal and flat surface. 53 stops Stops are intended to prev
27、ent the screen from sliding but not from overturning. They shall be not higher than 12 mm except in cases when the design of the screen needs the use of higher stops. In this case, the lowest position to prevent the screen from sliding shall be used. 53 Loadiugpad A rigid cylindrical pad, 200 mm in
28、diameter, with a flat face and a 12 mm edge radius. 5.4 Horizontal force application device A device which can apply a horizontal force through the loading pad (5.3). The device shall not hinder fiee movement of the screen being tested. 5.5 Vertical force application device A device which can apply
29、a vertical force through the loadi ig pad (5.3).

30、to horizontal forces. 6.1.2 Test procedure Examine the recommendations provided by the manufacturer to determine the screen configuration least favourable for stability. Place the screen configuration on the test surface (5.1). Restrain the base of the screen configuration by stops (5.2) as shown in
31、 Figure 1, Apply on the screen configuration a gradually increasing horizontal force, through the horizontal force application device (5.4). The force shall be applied at the least favourable position alongside a horizontal line at 1 300 mm above the floor, unless the top of the screen is lower than
32、 1 400 mm, in which case the height of the force application shall be 1 O0 mm lower than the screen height. Increase the force until either a 200 N force maximum is attained or until the screen is displaced 200 mm at the point of application. O BSI 08-2000 STDIBSI BS EN 3023-3-ENGL 2000 Lb24bb9 08b5

34、ot overturn when submitted to horizontal forces. 6.2.2 Test procedure Examine the recommendations provided by the manufacturer to determine the screen configuration, with all add-on elements, least favourable for stability. Place the screen configuration on the test surface (5.1). Restrain the base
35、of the screen configuration by stops (5.2) as shown in Figure 3. Load the add-on elements up to the worst case permitted by the manufacturers instructions, taking into account the min. and max. width of the screens recommended by the manufacturer. The worst case may mean a combination of loaded and
36、unloaded units. Moveable parts of add-on elements shall not be restrained from moving during this test. Apply on the screen configuration a gradually increasing horizontal force, through the horizontal force application device (5.4). The force shall be applied at the least favourable position alongs
37、ide a horizontal line at 1 300 mm above the floor, unless the top of the screen is lower than 1 400 mm, in which case the height of the force application shall be at 100 mm lower than the screen height. Increase the force until either a 200 N force maximum is attained or until the screen is displace
38、d 200 mm at the point of application. Repeat the test on the opposite side of the screen configuration. 8 BSI 08-2000 Page 8 EN 1023-3:2000 Worktop Shelves Hanging cupboards Figure 2 - Examples of add-on elements i I I.
