18、e 3 EN 1725 : 1998 Introduction This European Standard has been prepared in order to provide assurance that domestic beds complying with the requirements are reasonably safe. It is intended to prevent serious injury through normal functional use, as well as misuse that might reasonably be expected t
19、o occur. It should be understood that the tests do not ensure that structural failure will not eventually occur as a result of habitual misuse or after an excessively long period of use. 1 scope This European Standard specifies mechanical safety requirements and testing for all types of fully erecte
20、d domestic adult beds including all component elements such as bed frame, bed base, mattress and mattress pads (when they form a unit with the mattress). It does not apply to foldaway beds, bunk beds, children cots and adjustable beds for disabled persons where separate Standards exist, as well as w
21、aterbeds and air beds. Further tests may be applicable for test units that are multi purposes, e.g. convertible sofa beds and power driven system. Assessment for ageing and degradation are not included. 2 Normative references This European Standard incorporates, by dated or undated reference, provis
22、ions 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
23、 amendment or revision. For undated references, the latest edition of the publication referred to applies.

24、itut Fur Normung E.V.- EnglishLicensed by Information Handling ServicesPage 4 EN 1725 : 1998 3 Definitions For the purposes of this standard the following definitions apply : 3.1 unframed slat base Bed base consisting of separate slats flexibly held together normally by means of textile, rubber or p
25、lastic tape. NOTE : When loading one slat, the load is transferred to the support by that slat only. 3.2 framed base Bed base consisting of slats, springs, etc. which are connected to a structural frame system. NOTE : When loading one component only, e.g. a slat or a spring, the load is distributed
26、by the frame to the support. 3.3 framed sprung mattress Upholstered bed base consisting of springs, topped with fillings, on a rigid frame to be used in a bed frame or freestanding. 3.4 divanbase Upholstered bed base used without the need of any framework. It may be constructed with a spring filling
27、 or a solid top and may include drawers or storage facilities. 4 General test conditions 4.1 Preliminary preparation Before any of the tests are commenced, the test unit shall be old enough to ensure that it has developed its full strength. The test unit shall be tested as delivered. Knock-down furn
28、iture shall be assembled according to the instructions supplied with it. If the test unit 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 if applicable. Further tightening shall not take p
29、lace unless this is specifically required by the manufacturer. The test unit shall be stored in indoor ambient conditions for at least one week immediately prior to testing. Any deviation from this procedure shall be stated in the report. The tests shall be carried out in indoor ambient conditions b
30、ut if during a test the atmospheric temperature is outside the range 15 C to 25 C, the maximum and/or minimum temperature shall be recorded in the test report.

31、The forces in static load and durability tests shall be applied sufficiently slowly to ensure that negligible dynamic load is applied. Test forces, unless otherwise stated, may be applied by any suitable device because results are not dependent upon the apparatus. 4.3 Tolerances Unless otherwise sta
32、ted : - all forces shall have an accuracy of f 5 % of the nominal force ; - all masses shall have an accuracy of f 0,5 % of the nominal mass ; - all dimensions shall have an accuracy of k 1 mm of the nominal dimension. The tolerance for position of loading pads shall be f 5 mm. 4.4 Sequence of testi
33、ng All tests specified for a particular part shall be carried out on the same sample. The tests shall be carried out in the sequence laid down in this standard. 5 Test environment and apparatus 5.1 Floor surface Rigid, horizontal and flat. 5.2 Stops Stops shall be used to prevent the bed from slidin
34、g but not tilting and shall be no higher than 12 mm except in cases where the design of the bed requires the use of higher stops ; in which case the lowest that will prevent the bed from moving, shall be used. 5.3 Standard test mattress Flexible polyether foam with a thickness of 100 mm, a density o
35、f (30 f 2) kg/m3 and an indentation hardness index of (170 I 20) N in accordance with A40 in ISOIDIS 2439. The size of the mattress shall be such as to overlap the size of the loading pad by at least 100 mm ali round. The test mattress shall have a cover with the following characteristics: Compositi
