23、(E) 4 1 Scope This European Standard specifies safety, strength and durability requirements for work tables and desks for office tasks to be undertaken in a seated, a sit-stand or standing position. It does not apply to other tables in the office area, which are covered by EN 15372. Annex A (informa
24、tive) contains a test for the deflection of tables tops. Annex B (informative) contains an example of calculation of the stiffness of the structure. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applicat
25、ion. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

26、 the purposes of this document, the following terms and definitions apply. 3.1 accessible part part to which access can easily be gained by the user when the table is in its intended configuration of use and for which the probability of unintentional user contact is high 3.2 part accessible during s
27、etting up and folding part to which access can only be gained when setting up and folding the table 3.3 shear and squeeze point gap which can cause harm to fingers and which occurs when two accessible parts move relative to each other 3.4 overturn event at which a table pivots to a point beyond whic
28、h the table continues to fall 4 Safety requirements 4.1 General The table shall be designed so as to minimize the risk of injury to the user. All parts of the table with which the user comes into contact during intended use, shall be designed so that physical injury and damage are avoided. These req
29、uirements are fulfilled when: a) all accessible edges and corners are free from burrs and rounded or chamfered; b) the edges and corners of the top surfaces are chamfered not less than 1 mm by 1 mm or rounded with a radius of not less than 2 mm; DIN EN 527-2:2017-03 EN 527-2:2016 (E) 5 c) the ends o
30、f feet and tubular components are closed or capped. Movable and adjustable parts shall be designed so that injuries and inadvertent operation are avoided. It shall not be possible for any load bearing part of the table to come loose unintentionally. All parts which are lubricated to assist sliding s
31、hall be designed to protect users from lubricant stains when in normal use. 4.2 Shear and squeeze points 4.2.1 Shear and squeeze points when setting up and folding Unless 4.2.2 or 4.2.3 are applicable, shear and squeeze points that are created only during setting up and folding are acceptable, becau
32、se the user can be assumed to be in control of his/her movements and to be able to cease applying the force immediately upon experiencing pain. The edges of parts moving relative to each other and creating shear and squeeze points shall be as specified in 4.1. 4.2.2 Shear and squeeze points under in
33、fluence of powered mechanisms There shall be no shear and squeeze points which close to less than 25 mm unless they are always less than 7 mm created by parts of the table operated by powered mechanisms, i.e. springs, gas lifts and motorized systems. 4.2.3 Shear and squeeze points during use There s
34、hall be no shear and squeeze points which close to less than 25 mm unless they are always less than 7 mm created by forces applied during normal use or created by the user during normal movements and actions, e.g. attempting to move the table. 4.3 Stability requirements The table shall not overturn
35、when tested according to tests 10 and 11 of Table 1. 4.4 Structural safety requirements The structural safety requirements are fulfilled when the requirements according to 5.2 are fulfilled. 5 Strength and durability 5.1 General Tables shall be tested according to Table 1 and following the order lis
36、ted in Table 1. With the exception of test 9 Drop test, work tables supplied with storage features shall be tested with the following loads in the storage feature: extension elements: 0,5 kg/dm3; suspended pocket files: 4 kg/dm.
