BS EN 12727:2016EN 12727:2016 (E) 4 1 Scope This European Standard specifies requirements determining the safety, structural strength and durability of al
18、l types of seating that are permanently fastened to the floor and/or wall, whether in bench or individual seat form. This standard does not apply to linked seating not fastened to the floor and/or walls and street furniture. It does not include requirements for resistance to ageing, degradation, fla
19、mmability, the effect of ambient temperature and the durability of upholstery materials. The standard has two annexes: Annex A (normative) Additional test methods; Annex B (informative) Test severity in relation to application. 2 Normative references The following documents, in whole or in part, are
20、 normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 1728:2012, Furniture - Seating - Test methods for the
21、 determination of strength and durability 3 Terms and definitions For 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 seating is in the intended configuration of use and for which the probabi
22、lity of intentional user contact is high 3.2 shear and squeeze points shear and squeeze points exist if the distance between two accessible parts moving relatively to each other is less than 18 mm and more than 7 mm for adults in any position during movement 3.3 structure load bearing parts of furni
23、ture such as the frame, seat, back and arm supports and suspension 3.4 auxiliary writing surface small work surface for writing or similar activities 4 Test conditions General test conditions shall be in accordance with EN 1728:2012, Clause 4. BS EN 12727:2016EN 12727:2016 (E) 5 5 Safety, strength a
24、nd durability 5.1 General requirements The seating shall be so designed as to minimize the risk of injury to the user. All accessible parts (3.1) shall be so designed that physical injury and damage are avoided. This requirement is met when: a) accessible corners and edges are rounded or chamfered;
25、b) all other corners and edges are free from burrs and sharp edges; c) ends of hollow components with a diameter greater than 7 mm and less than 12 mm, where the accessible depth is greater than 10 mm, are closed or capped. Movable and adjustable parts shall be designed so that injuries and inadvert
26、ent operation are 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 squee
27、ze points when setting up and folding Unless 5.2.2 or 5.2.3 are applicable, shear and squeeze points that are created only during setting up and folding, including tipping seat actions, are acceptable, because the user can be assumed to be in control of his/her movements and to be able to cease appl
28、ying 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 5.1. 5.2.2 Shear and squeeze points under influence of powered mechanism With the exception of tipping seats, there shall be no shear and
29、 squeeze points created by parts of the seating operated by powered mechanisms, e.g. springs and gas lifts. 5.2.3 Shear and squeeze points during use There shall be no shear and squeeze points created by forces applied during normal use, see Table 1. There shall be no shear and squeeze points if a h
30、azard is created by the weight of the user during normal movements and actions, e.g. by adjusting the backrest. NOTE This hazard is best prevented by the use of automatic locking mechanisms. 5.3 Strength and durability 5.3.1 General Seating shall be tested for strength and durability according to th
31、e order of Table 1. The guidance for selecting test severity with due respect for the end use of the product is given in Annex B. For multiple seating units, all seats not undergoing testing shall be loaded with 950 N when required by EN 1728:2012. BS EN 12727:2016EN 12727:2016 (E) 6 Table 1 Strengt

A.1.2 Test Procedure The horizontal force as specif
43、ied in Table 1 shall be applied acting forwards using the smaller seat loading pad (EN 1728: 2012, 5.6) 50 mm below the centre of the top of the back of one end seat only. The force shall be applied for the number of cycles specified in Table 1. BS EN 12727:2016EN 12727:2016 (E) 9 Annex B (informati
44、ve) Test severity in relation to application Table B.1 shows the type of use that might be expected from furniture in relation to the four test severities contained in Table 1. It should be emphasized that there are applications where moderate usage can be combined with high frequency of use and vic
45、e versa. Therefore the precise nature of the intended use of a ranked seating installation should be carefully considered before selecting the appropriate loads and cycles from Table 1.
