DIN EN 12520:2016-03 EN 12520:2015 (E) 4 1 Scope This European Standard specifies the minimum requirements for the safety, strength
20、and durability of all types of domestic seating for adults. It does not apply to ranked seating, seating for non-domestic use, office work chairs, office visitors chairs, chairs for educational institutions, outdoor seating and to links for linked seating for which European Standards exist. It does
21、not include requirements for the durability of upholstery materials, castors, reclining and tilting mechanisms and seat height adjustment mechanisms. It does not include requirements for electrical safety. It does not include requirements for the resistance to ageing, degradation, flammability and e
22、rgonomics. The tests are based on use by persons weighing up to 110 kg. 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. For undated refere
23、nces, the latest edition of the referenced document (including any amendments) applies. EN 1022, Domestic furniture - Seating - Determination of stability EN 1728:2012 , Furniture - Seating - Test methods for the determination of strength and durability 3 Terms and definitions For the purposes of th
24、is document, the following terms and definitions apply. 3.1 accessible part part to which access can easily be gained by the user when the seating is in its intended configuration of use and for which the probability of unintentional user contact is high 3.2 part accessible during setting up and fol
25、ding part to which access can only be gained when setting up and folding the furniture 3.3 shear and squeeze point shear and squeeze point exists if the distance between two accessible parts moving relative to each other can be more than 7 mm or less than 18 mm in any position during movement 4 Test
26、 sequence The tests shall be carried out in the order in which they are listed in this document. 5 Constructional requirements 5.1 General requirements All parts of the seating with which the user comes into contact, during intended use, shall be designed to ensure that physical injury and damage ar
27、e avoided. N1)National footnote: Corresponds to DIN EN 1728:2014-02, Furniture Seating Test methods for the determination of strength and durability (EN 1728:2012 + AC:2013) N1)DIN EN 12520:2016-03 EN 12520:2015 (E) 5 These requirements are met when: a) edges of the seat, back rest and arm rests, wh
28、ich are in contact with the user when sitting are rounded or chamfered. All other edges accessible during use shall be free from burrs and/or sharp edges; b) ends of hollow components are closed or capped. Movable and adjustable parts shall be designed so that injuries and inadvertent operation are
29、avoided. It shall not be possible for any load bearing part of the seating to come loose unintentionally. All parts which are lubricated to assist sliding shall be designed to protect users from lubricant stains when in normal use. 5.2 Shear and squeeze points 5.2.1 Shear and squeeze points when set
30、ting up and folding Unless 5.2.2 or 5.2.3 are applicable, shear and squeeze points, as defined in 3.3, that are created only during setting up and folding, including tipping seat, are acceptable, because the user can be assumed to be in control of his/her movements and to be able to cease applying t
31、he 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 5.1. 5.2.2 Shear and squeeze points under influence of powered mechanisms With the exception of tipping seats there shall be no shear and squee
32、ze points created by parts of the seating under powered mechanisms, e.g. springs and gas lifts. NOTE Electrically operated seating is covered by EEC Directives for EMC, Machinery, Low Voltage or Medical Devices. 5.2.3 Shear and squeeze points during use There shall be no shear and squeeze points cre
33、ated by loads applied during normal use. The loads applied during normal use can be found in Table 1. Shear and squeeze points are not acceptable if a hazard is created by the weight of the user during normal movements and actions, e.g. attempting to move the seating by lifting the seat or by adjust
34、ing the backrest. NOTE This hazard is best prevented by the use of automatic locking mechanisms. 5.3 Stability The seating shall fulfil the relevant requirements of EN 1022. 5.4 Strength and durability 5.4.1 General Seating shall be tested for strength and durability according to and in the order gi
35、ven in Table 1 and in accordance with the test conditions contained in EN 1728:2012. DIN EN 12520:2016-03 EN 12520:2015 (E) 6 Table 1 Tests and test sequence Test Reference Test parameters 1.

41、ting not tested in accordance with Test 12. dIn derogation of EN 1728:2012 the loading points shall be 80 mm from the relevant edges of the seat. eThe minimum back force is the force that just prevents rearward overturning.

42、rements The strength and durability requirements are fulfilled when during and after testing in accordance with Table 1: a) there are no fractures of any member, joint or component; b) there are no loosening of joints intended to be rigid; c) seating fulfils its functions after removal of the test l
43、oads; d) seating fulfils the stability requirements. 6 Information for use Information for use shall be available in the language of the country in which it will be delivered to the end user.
