21、les without regard to materials, design/construction or manufacturing processes. The tests are designed to be applied to an article of furniture that is fully assembled and ready for use. Not all tests are necessarily applicable to all types of tables. This European Standard does not apply to outdoo
22、r tables and changing tables, for which specific standards exist. Test methods for the assessment of ageing and degradation are not included. This standard does not include any requirements. Safety requirements can be found in prENV 12521:1999. 2Normative references This European Standard incorporat
23、es by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European
24、Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

EN 1727Domestic furniture - Storage furniture - Safety requirements and test methods 3Definitions For the purpose of this European Standard, the following definitions apply: 3.1 static tests: Tests consisting of heavy loads
26、 being applied a few times to ensure that the furniture has sufficient strength under the highest levels of loading that might reasonably be expected to occur. 3.2 impact tests: Tests to assess the strength of the article under shock loading that occasionally occur. 3.3 fatigue tests: Tests simulati
27、ng the repeated application of loads or movement of components occurring during normal long-term use. 3.4 structure: The load bearing parts of furniture such as the frame, top and legs. 3.5 stability: Ability to withstand forces that tend to cause the article to overturn. 3.6 ancillary surface: A su
28、rface additional to the main surface intended for occasional use as part of the table top. e.g. flaps or extension leaves.

29、eliminary preparation Before any of the tests are commenced, the item shall be old enough to ensure that it has developed its full strength. The test unit shall be tested as delivered. Knock-down furniture shall be assembled according to the instructions supplied with it. If the test unit can be ass
30、embled or combined in different ways, the most adverse combination shall be used for each test. Knock-down fittings shall be tightened before testing if applicable. Further tightening shall not take place unless this is specifically required by the manufacturer. The test unit shall be stored in indo
31、or ambient conditions for at least one week immediately prior to testing. Any deviation from this procedure shall be recorded in the report. The tests shall be carried out in indoor ambient conditions, but if during a test the atmospheric temperature is outside the range of 15C to 25C, the maximum a
32、nd/or minimum temperature shall be recorded in the test report. 4.2Application of forces The forces in fatigue and static load tests shall be applied sufficiently slowly to ensure that dynamics forces are negligible. The forces in fatigue tests shall be applied sufficiently slowly to ensure that hea
33、ting does not occur. Unless otherwise stated, static loads shall be maintained for (10 2) seconds and fatigue test loads shall be maintained for (2 1) seconds. 4.3Tolerances For tolerances, unless otherwise stated: - forces shall have an accuracy of 5 % of the nominal force; - masses an accuracy of
34、0,5 % of the nominal mass; - dimensions an accuracy of 1 mm of the nominal dimension. The tolerance for position of loading pads shall be 5 mm. 5Test equipment and apparatus Unless otherwise stated, the tests may be applied by any suitable device because the results are not dependent upon the appara
35、tus. 5.1Vertical force application device A device capable of applying either a fixed vertical force, or a gradually increasing vertical force. The device shall not hinder the free movement of the article. Licensed Copy: sheffieldun sheffieldun, na, Mon Oct 30 12:35:59 GMT+00:00 2006, Uncontrolled C
36、opy, (c) BSI Page 6 EN 1730:2000 BSI 19 October 2001 5.2Horizontal force application device A device capable of applying a gradually increasing horizontal force to an article at the height of its top. The device shall be capable of applying the force at the required angle of inclination of the horiz
37、ontal (see 6.2) and shall not hinder the free movement of the article. 5.3Vertical impactor (see Figure 1) 5.3.1Cylindrical body, approximately 200 mm in diameter, separated from the striking surface by helical compression springs and free to move relative to it on a line perpendicular to the plane
38、of the central area of the striking surface. The body and associated parts minus the springs shall have a mass of (17 0,1) kg and the whole apparatus, including body, springs and striking surface, shall have a mass of (25 0,1) kg. 5.3.2Springs. Such that the combined spring system has a nominal spri
39、ng rate of (6,9 1) N/mm and the total frictional resistance of the moving parts shall be between 0,25 N and 0,45 N. The spring system shall be compressed to initial load of (1040 5) N (measured statically) and the amount of spring compression movement available from the initial compression point to
40、point where the springs become fully closed shall not be less than 60 mm. 5.3.3Striking surface, shall be a rigid circular object, 200 mm in diameter, the face of which has a convex spherical curvature of 300 mm radius with a 12 mm front edge radius. 5.4Floor Horizontal, flat and rigid with a smooth
41、 surface. For the drop test (6.9) a rubber mat 2 mm thick, with hardness (85 5) IRHD according to ISO 48 shall cover a concrete floor.

Stops shall not be higher
43、 than 12 mm except in cases where the design of the article necessitates the use of higher stops, in which case the lowest stop that will prevent the article from sliding shall be used. 5.6Loading pad Rigid cylindrical object, 100 mm in diameter, with a flat face and a 12 mm edge radius. 5.7Foam for
44、 impact tests Two 25 mm thick layers of polyether foam with a hardness index according to ISO 2439, method A, of (1100 100) N. They shall be positioned between the loading pad and the test unit. For use of the foam with the impactor test, see 6.6. 6Test procedures In the case of design not catered f
45、or in the test procedures, the test shall be carried out as far as possible as described, and deviations from the test procedure recorded in the test report. 6.1Drawer loads The volume of drawers shall be taken as the area of the drawer bottom multiplied by the clear height. The clear height is the
46、distance between the top of the drawer bottom and the lower edge of the front of the drawer above or the structure of the unit. Drawers with a clear height of 110 mm or less shall be loaded with 0,35 kg/dm volume; all other drawers shall be loaded with 0,20 kg/dm volume. 6.2Horizontal static load te
47、st Position the table on the test surface, in its normal position of use. Restrain the base of the table by placing stops (5.5) around each leg/base (in all directions) on one short side (figure 2a). Load all drawers, if there are any, as specified in 6.1 and maintain the drawers closed. Apply the f
48、orce for the number of cycles specified in the requirement document by means of the horizontal force application device (5.2) alternately at the centre of each short side (figure 2a). If the table tends to overturn, incline the test force downwards gradually until the table is just prevented from ov
49、erturning (see 6.2.1). One application at point A and one at point B represents one cycle. If the table is non-symmetrical about its transverse centre line, carry out the test first with the stops positioned at one end and then repeat with the stops at the opposite end.
