21、ring processes. This document does not apply to outdoor furniture for severe contract use where higher requirements may be necessary, nor does it apply to street furniture and furniture permanently fixed to the ground/wall. Annex A (informative) specifies guidelines for purchase information. Informa
22、tion regarding ageing and degradation caused by light, temperature and moisture has not been included. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the l
23、atest edition of the referenced document (including any amendments) applies.

24、ty 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 outdoor tables for contract use outdoor tables intended for non-private use in places with public access such as restaurants, open-air swimming pools, beaches and vocational and leisure sites
25、 3.2 outdoor tables for domestic use outdoor tables intended for private use in places without public access such as gardens, winter gardens, terraces, balconies etc 3.3 outdoor tables for camping use outdoor tables, foldable or knock-down and light-weight, intended for use in connection with campin
26、g and travelling 4 General test conditions The general test conditions shall be as specified in EN 1730 with the exception of the conditioning time, which shall be at least 24 h, instead of 1 week. The tests are described in terms of the application of forces. Masses, however, can be used. The relat
27、ionship 10 N = 1 kg shall be used for this purpose.

28、. 5.2 Floor Horizontal, flat and rigid with a smooth surface. NOTE Examples of suitable floors: Plastics laminate, Bakelite board and steel. 5.3 Steel test tube A steel tube, 18 mm in diameter and a 1,5 mm wall thickness with a length that allows a force to be applied from 2 200 mm above the floor.
29、6 Test methods and requirements 6.1 General The general safety requirements stated in EN 581-1 shall be fulfilled. The table shall not overturn when tested according to clause 6.2. At the end of each test specified in clause 6.3 and clause 6.4, there shall be no structural damage or other deteriorat
30、ion that affects safety, and the table shall fulfil its functions (i.e. folding, unfolding, adjustments, operation of extensions etc). 6.2 Stability 6.2.1 Stability test under vertical load Measure the largest dimension of the table top. NOTE 1 For rectangular tables, the largest dimension to consid
31、er is the length. The diagonal is not to consider as a dimension in this case. Using this dimension, determine the force F, as follows (see also Figure 2): Camping use: F = 200 Domestic use: For L smaller than 800 mm F = 200 N For L between 800 mm and 1600 mm F = L/4 N For L larger than 1 600 mm F =
32、 400 N Contract use: For L smaller than 800 mm F = 200 N For L between 800 mm and 1 000 mm F = L-600 N For L larger than 1 000 mm F = 400 N If the table is fitted with drawers, these shall not be loaded during this test.

33、opy, (c) BSIEN 581-3:2007 (E) 6 The vertical force F shall be applied to the side where the load is most likely to cause overturning, as far away from the supports as possible, and at a point 50 mm from the outer edge of the table top (see Figure 1).

This test only applies to tables that do not require parasols to be used with their own bases. Secure the steel test tube (5.3) in the tables fixture for holding parasols. Apply a horizontal f
36、orce F of 30 N at a height h of 2 200 mm (see Figure 3). Figure 3 shows an example of a table where the structure is intended to support a parasol.

Apply, according to EN 1730, the force(s) F, specified in Table 1, at the following application point(s): for a table top length L 1 600 mm, at the geometric centre of the table (see Figure 4), for a ta
38、ble top length L 1 600 mm, at 2 points positioned on the longitudinal axis of the table top with 400 mm on either side of the transversal axis (see Figure 5), Licensed Copy: Wang Bin, na, Thu Aug 09 02:42:55 GMT+00:00 2007, Uncontrolled Copy, (c) BSIEN 581-3:2007 (E) 8 for table tops with central ex
39、tension(s), assemble the extension(s), and apply the force(s) at 1 or 2 point(s) as specified above. NOTE If necessary, a foam layer may be used between the loading pad and the test surface. Carry out for the number of cycles specified in Table 1, with 5 s to 10 s between applications. Figure 4 Stre

41、r (5.2) in normal position of use. Load the table top with an evenly distributed load sufficient to prevent overturning during the test. In the extended configuration, apply a force F, 100 mm from the outer edge of the table top, at the middle of the width (see Figure 6). NOTE If necessary, a foam l
42、ayer may be used between the loading pad and the test surface. Carry out for the number of cycles specified in Table 1, with 5 s to 10 s between applications. Figure 6 Strength of end extensions 6.4 Horizontal fatigue test Restrain the base of the table by placing stops around each leg/base (in all
43、directions). Place a mass M, specified in Table 1, at the geometric centre of the table top so that the table remains horizontal during testing. Apply two alternating horizontal forces, specified in Table 1, using, e.g. masses, string and pulley, at the height of the top surface by means of two load
44、ing pads. These should be applied to the application points specified in Figure 7. The test may be carried out in a one stage cycle a, c, b, d or in a two stage cycle a, b followed by c, d. If the table tends to tilt in one direction of loading at a load less than that specified, reduce the horizont
45、al force until tilting is just prevented in that direction only. Carry out the test using this reduced force in that direction only. Record the value of any reduced force used. Carry out the test for the number of cycles specified in Table 1. Licensed Copy: Wang Bin, na, Thu Aug 09 02:42:55 GMT+00:0
