This European Standard shall be given the status of a national standard, either by publication of an identical text or by endo
22、rsement, at the latest by April 2013, and conflicting national standards shall be withdrawn at the latest by April 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identify
23、ing any or all such patent rights. This document supersedes EN 1730:2000. The main changes with respect to the previous edition are listed below. All test methods for seating used in European Standards for furniture have been collated in one document. The document now contains methods that were prev
24、iously listed in EN 581-3, Outdoor furniture, EN 527-3, Office Work Tables and Desks and EN 15372, Non-domestic tables. A durability test for tables with castors has been added. A durability test for height adjustment mechanisms has been added. Wherever possible test methods have been simplified and
25、 clarified for ease of use. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republ
26、ic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. DIN EN 1730:2013-01 EN 1730:2012 (E) 4 1 Scope This Europea
27、n Standard specifies test methods for the determination of stability, strength and durability of the structure of all types of tables and desks without regard to use, materials, design/construction or manufacturing process. This European Standard does not apply to changing units which are covered by
28、 other European Standards. Test methods for the assessment of ageing, degradation, and electrical functions are not included. This European Standard does not apply to the strength and durability of any storage features that are covered by other European Standards. This European Standard does not inc
29、lude any requirements. Requirements for different end uses can be found in other Standards. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies
30、. For undated references, the latest edition of the referenced document (including any amendments) applies.

31、r the purposes of this document, the following terms and definitions apply. 3.1 structure load bearing parts of furniture such as the frame, top and legs 3.2 ancillary surface surface additional to the main surface intended for occasional use as part of the table top 3.3 duty cycle length of time th
32、e height adjustable tables drive system may be operated without impairing its useful life 3.4 levelling device device intended to keep the table top horizontal e.g. adjustable feet or similar DIN EN 1730:2013-01 EN 1730:2012 (E) 5 4 General test conditions 4.1 Preliminary preparation The furniture s
33、hall be tested as delivered. Knock-down furniture shall be assembled according to the instructions supplied with it. If the instructions allow the furniture to be assembled or combined in different ways, the most adverse combination shall be used for each test. Knock-down fittings shall be tightened
34、 before testing. Further tightening shall not take place unless specifically required by the manufacturer. Unless otherwise specified by the manufacturer, the sample for test shall be stored in indoor ambient conditions for at least 24 h immediately prior to testing. The tests shall be carried out a
35、t indoor ambient conditions but if during a test the temperature is outside the range 15 C to 25 C the maximum and/or minimum temperature shall be recorded in the test report. The test for deflection of table tops (see 6.7), except those made from metal, glass and stone, shall be carried out at a re
36、lative humidity of (50 5) % and a temperature of (23 2) C. 4.2 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. The forces in durability tests shall be applied sufficiently slowly to ensu
37、re 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 maintained for (2 1) s. The forces may be replaced by masses. The relationship 10 N = 1 kg shall be used. 4.3 Tolerances Unless otherwise
38、 stated, the following tolerances are applicable to the test equipment: Forces: 5 % of the nominal force; Velocities: 5 % of the nominal velocity; Masses: 1 % of the nominal mass; Dimensions: 1 mm of the nominal dimension; Angles: 2oof the nominal angle. The accuracy for the positioning of loading p
39、ads and impact plates shall be 5 mm. NOTE For the purposes of uncertainty measurement, test results are not considered to be adversely affected when the above tolerances are met. 5 Test Equipment and Apparatus Unless otherwise stated, the tests may be applied by any suitable device because the resul
40、ts are not dependent upon the apparatus, except in the case of impact tests where the apparatus described in 5.2 shall be used. The equipment shall not inhibit deformation nor cause unnatural deformation of the unit/component, i.e. it shall be able to move so that it can follow the deformation of th
41、e unit/component during testing. DIN EN 1730:2013-01 EN 1730:2012 (E) 6 With the exception of the horizontal static, durability and stiffness tests, described in 6.2 and 6.4, all loading pads shall be capable of pivoting in relation to the direction of the applied force and the pivot point shall be
42、as close as practically possible to the load surface. Loading pads for the horizontal static, durability and stiffness tests, described in 6.2 and 6.4, shall not pivot. With the exception of the horizontal static, durability and stiffness tests described in 6.2 and 6.4, if a loading pad tends to sli
43、de, use a slip resistant material between the loading pad and the surface being tested. 5.1 Vertical impactor, as shown in Figure 1 and comprised of the following: 5.1.1 Circular body, 200 mm in diameter separated from the striking surface by helical compression springs and free to move relative to
44、it on a line perpendicular to the plane of the central area of the striking surface. The body and associated parts minus 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. 5.1.2 Springs, which shall be
45、 such that the nominal spring rate of the combined spring system is (7 2) N/mm and the total friction resistance of the moving parts is less than 1 N. The spring system shall be compressed to an initial load of (1 040 5) N (measured statically) and the amount of spring compression movement available
46、 from the initial compression point to the point where the springs become fully closed shall be not less than 60 mm. 5.1.3 Striking surface, which shall be a 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.
