Möbel - Tische - Prüfverfahren zur Bestimmung der Standsicherheit, Festigkeit und Dauerhaltbarkeit This European Standard was approved by CEN on 18 August 2012.
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has the same status as the official versions.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic 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 United Kingdom.

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 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 Republic 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.

± 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:
± 2o of the nominal angle. The accuracy for the positioning of loading pads 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 results 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 the unit/component during testing. SIST EN 1730:2012

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 slide, 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 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 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 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.

5.2 Floor, horizontal, flat and rigid with a smooth surface. For the drop test (6.9) the floor shall be faced with a 2 mm thick layer of rubber with a hardness of 85 ± 10 IRHD according to ISO 7619-2. SIST EN 1730:2012

If a test cannot be carried out as specified in this standard, e.g. because a loading pad cannot be used for the application of a force due to the design of a product, the test shall be carried out as far as possible as specified. Tables supplied with storage features shall be tested with the specified load in the storage item. 6.2 Horizontal static load test Position the table on the test surface, in its normal position of use without extending, or inserting, ancillary surfaces. Unless otherwise specified, height adjustable tables shall be set to their highest position. Restrain the base of the table by stops placed in all directions at the opposite end to that at which the horizontal test force is first to be applied. Apply the specified mass to an area of (300 ± 50) mm x (300 ± 50) mm, or a diameter of (300 ± 50) mm, to the approximate centre of the table top. Apply the specified horizontal force by means of the loading pad (5.4) at the table top level in a direction perpendicular to a line joining the two legs/supports, midway between the legs/supports.
