EN 15373:2007 (E) 3 Foreword This document (EN 15373:2007) has been prepared by Technical Committee CEN/TC 207 “Furniture”, the secretariat of which is held by UNI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2007, and conflicting national standards shall be withdrawn at the latest by October 2007. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.



EN 15373:2007 (E) 4 1 Scope This European standard specifies requirements for the safety, strength and durability of all types of non-domestic seating for adults. It does not apply to ranked seating, office work chairs, office visitors chairs, chairs for educational institutions, outdoor seating and to links for linked seating for which European standards or drafts exist. It does not include requirements for the durability of upholstery materials, castors, reclining and tilting mechanisms and seat height adjustment mechanisms.
The test requirements contained within this standard are based on use by persons weighing up to 110 kg.
It does not include requirements for resistance to ageing, degradation and flammability. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 1022:2005, Domestic furniture – Seating – Determination of stability EN 1335-1:2000, Office furniture – Office work chair – Part 1 : Dimensions – Determination of dimensions EN 1335-3:2000, Office furniture – Office work chair – Part 3 : Safety test methods
EN 1728:2000, Domestic furniture - Seating - Test methods for the determination of strength and durability 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 accessible parts parts 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 parts accessible during setting up and folding parts to which access can only be gained when setting up and folding the furniture
3.3 shear and squeeze points shear and squeeze points exist if the distance between two accessible parts moving relative to each other can be less than 18 mm or more than 7 mm in any position during movement 3.4 castor type H castors with rigid wheels, i.e. hard treads
NOTE 1 The wheel is of one colour over the entire surface NOTE 2 These castors are suitable for carpeted floors.



EN 15373:2007 (E) 5 3.5
castor type W castors with resilient tyred wheels, i.e. soft treads
NOTE 1 This is clearly a different colour to the wheel centre NOTE 2 These castors are suitable for hard stone, wooden or tiled floors or those featuring non-textiled covering. 4 Test sequence The tests shall be carried out in the order in which they are listed in this Standard. 5 Safety requirements 5.1 General The seating shall be designed so as to minimise the risk of injury to the user. All parts of the seating with which the user comes into contact during intended use, shall be designed so that physical injury and damage are avoided. This requirement is met when: 1. Edges of the seat, back rest and arm rests which are in contact with the user when sitting in the seating are rounded or chamfered and all other edges accessible during use are free from burrs and/or sharp edges. 2. Ends of hollow 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 seating to come loose unintentionally.
All parts that 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 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 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 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 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.



EN 15373:2007 (E) 6 There shall be no shear and squeeze points 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 adjusting the backrest. NOTE This hazard is best prevented by the use of automatic locking mechanisms. 5.3 Stability 5.3.1 General The seating shall not overturn
