Introduction This part of EN 13453 specifies tests consisting of the application to various parts of the item, of loads or forces simulating normal functional use, as well as misuse that can reasonably be expected to occur. The tests are designed to evaluate properties without regard to materials, design/construction or manufacturing processes. SIST EN 13453-2:2004

1 Scope This part of EN 13453 specifies test methods that assess the safety, strength and durability of bunk beds and high beds for non domestic use. The corresponding safety requirements are given in EN 13453-1.[1] 2 Normative references This European Standard 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 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). EN 747-1, Furniture - Bunk beds for domestic use - Part 1 : Safety requirements. EN ISO 2439:2000, Flexible cellular 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 results 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 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 case 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 case 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 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.

Key 1 Joint of lifting device not inhibiting free fall Figure 1 — Bed base impacter The spring system shall be compressed to an initial 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 of 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 Rigid 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.
