The corresponding safety requirements are given in EN 13453-1.1 2 Normative references This European St
23、andard incorporates 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
24、 to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

25、lar polymeric materials - Determination of hardness (indentation technique) (ISO 2439:1997) 3 Test conditions 3.1 General The tests are designed to be applied to a bunk bed or high bed that is fully assembled and ready for use. The test results are only valid for the article tested. When the test re
26、sults are intended to be applied to other similar articles, the test specimen shall be representative of the production model. In the case of designs not catered for in the test procedures, the test shall be carried out as far as possible as described, and a list made of the deviations from the test
27、 procedure. 3.2 Preliminary preparation Before any of the test described in this part of EN 13453 are commenced, the bed 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 ca
28、se of glued joints in timber and the like. The bed shall be tested as delivered. If a knock-down type it shall be assembled according to instructions supplied with the bed. If the bed can be assembled or combined in different ways, the most adverse combination shall be used for each test. In the cas
29、e of bunk beds intended to be fastened together in pairs or attached to the structure of a building, they shall be tested as a single free standing bed unless the instructions specifically require attachment to another bunk bed or the building structure. Knock-down fittings shall be tightened before
30、 testing. Further tightening shall not take place unless specifically required by the manufacturer. The bed for test shall be stored in indoor ambient conditions for at least one week immediately prior to testing, any deviation from this procedure shall be recorded in the test report.

32、l be recorded in the test report. The test shall be carried out on the same bed in the same order as listed in this part of EN 13453. 3.3 Application of forces The test forces in durability and static load tests shall be applied sufficiently slowly to ensure that negligible dynamic load is applied.
33、The forces in durability tests shall be applied sufficiently slowly to ensure that kinetic heating does not occur. Unless otherwise stated static loads shall be maintained for (10 2) s. Unless otherwise stated durability loads shall be applied for (2 1) s. 3.4 Tolerances Unless otherwise stated: All
34、 forces shall have an accuracy of 5% of the nominal force; All masses shall have an accuracy of 1,0% of the nominal mass; All dimensions shall have an accuracy of 1,0 mm of the nominal dimensions; - All angles shall have an accuracy of 2% of the nominal angle. - The tolerance for the positioning of
35、loading pads shall be 5 mm. The tolerance for positioning loading pads shall be 5 mm. 4 Test equipment and apparatus 4.1 General The tests may, unless otherwise stated, be applied by any suitable device because results are dependent only upon correctly applied forces and loads and not upon the appar
36、atus. 4.2 Bed base impacter (see Figure 1) 4.2.1 Circular body, 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 of the central area of the striking surface. The body and associated parts minus
37、the springs shall have a mass of (17 0,1) kg and the whole apparatus, including mass, springs and striking surface, shall have a mass of (25 0,1) kg. 4.2.2 Springs, shall be such that the combined spring system has a nominal spring rate of (6,9 1) N/mm and the total friction resistance of the moving
38、 parts is between 0,25 N and 0,45 N.

39、load of (1040 5) N (measured statically) and the amount of spring compression movement available from the initial compression point to the point where the springs become fully closed shall be not less than 60 mm. 4.2.3 Striking surface, shall be a rigid circular object 200 mm in diameter, the face o
40、f which has a convex spherical curvature of 300 mm radius within a 12 mm front edge radius. 4.3 Loading pad 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 (see Figure 2). 4.4 50 mm diameter loading pad Rigi
41、d circular object 50 mm in diameter with a flat face and a 12 mm edge radius. 4.5 Test mattress Flexible polyether foam sheet with a thickness of 100 mm, a density of (30 2) kg/m3 and indentation hardness index of (170 20) N in accordance with A 40 in EN ISO 2439:2000. The dimensions shall be such a
42、s to overlap the size of the loading pad by at least 100 mm all round. The test mattress shall not have any cover. The same part of the test mattress shall not be re-used within two hours and the mattress shall be replaced after 5 tests. Licensed Copy: sheffieldun sheffieldun, na, Mon Oct 30 12:31:5

44、ere the design of the bed necessitates the use of higher stops, in which case the lowest that will prevent the bed from moving shall be used. 4.8 Floor surface Rigid horizontal flat and smooth. 5 Test procedures 5.1 Assembly and inspection before test Prior to the test, inspect the bed visually and
45、record any defects found.

46、ts, zips and other fittings are rounded or chamfered and free of burr and sharp edges. 5.3 Strength and durability tests 5.3.1 General Position the bed on the floor with all legs against stops (4.7). 5.3.2 Impact of bed base Place the test mattress (4.5) flat on the bed base. The impact shall be car
