EN 1129-2-1995 pdf download.Furniture-Foldaway beds Safety requirements and testing Part 2 : Test methods.
This Part of EN 1129 describes test methods that assess the safety of foldaway beds (hereafter referred to as “beds”) for domestic use.
Folding beds, camping beds, convertible bed/chairs or settees are not covered by this standard.
The tests are designed to be applied to a foldaway bed that is fully assembled and ready for use.
NOTE The test results arc only valid for the article tested. When the test results are intended to be applied to other similar articles, the test specimen should he representative of the
production model.
In the case of designs not catered for in the test procedures, the test should be carried out as far as possible as described, and a list made of the deviations from the test procedure.
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 I)ublications 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.
EN 1129-1:1995, Furniture—Foldaway beds— Safety requirements and testing — Part I: Safety requirements.
ISO 554, Standard atmospheres for conditioning and/or testing — Specifications.
ISO 2439, Polymeric materials, cellular flexible — Dci erm in at ion of hardness (indentation technique).
3 General
All forces shall have an accuracy of& 5 %, all masses an accuracy of± 0,5 % and all dimensions an accuracy of± 1 mm.
Before any of the tests described in this standard 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 joint in timber and the like.
Immediately before testing, the bed shall be stored for at least one week in a standardized atmosphere with a temperature of (23 ± 2) °C and a relative humidity of(50 ± 5) % in accordance with ISO 554.
The bed shall be tested as delivered. If of knock-down type, it shall be assembled in accordance with instructions supplied with the furniture. 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.
In the case of beds with adjustable characteristics, the test shall be carried out at both ends of the adjustment range.
4 Test equipment
NOTE The test forces 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 apparatus.
4.1 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 edge radius (see Figure 1).
4.2 Test mattress
Flexible polyether foam sheet with a thickness of 100 mm, a bulk density of(30 ± 2) kg/rn3 and an indentation hardness index of (170 + 20) N at 40% indentation in accordance with ISO 2439, at least 800 mm >c 800 mm in area, but not larger than the mattress base of the bed under test. The test mattress shall have no cover.
4.3 Stops
Stops shall be used to prevent the bed from sliding. but not tilting, and shall be no higher than 12 mm except in cases where the design of the bed necessitates the use of higher stops, in which case the lowest that will prevent the bed from moving.
4.4 Floor surface Horizontal and flat.
5 Testing procedures
5.1 Assembly and inspection before test Assemble the bed shall be assembled in accordance with the manufacturer’s instructions. Prior to the test, inspect the bed visually for defects.
5.2 Inspection of workmanship Inspect the bed to determine whether exposed edges, screws, bolts, and other fittings are rounded or chamfered and free of burrs and Shari) edges.
5.3 Opening and closing
Measure the opening and closing force at a slow constant rate of movement in order to eliminate dynamic forces.
Plot the opening and closing forces throughout the arc of opening of the bed. Take the results for both opening the bed and closing it and with the bed fitted with a mattress of the maximum and minimum weight stated in the instruction. Calculate the opening energy from the opening arc under the appropriate part of the resultant diagram (see Figure 2).EN 1129-2-1995 pdf download.
