chairs and tables If chairs in a range of size marks are all manufactured with the same design details and geometry, it is only necessary to carry out the complete test programme on the highest size mark (including multi-size and height adjustable) in the range, plus additional stability tests on the smallest size mark in the range If tables in a range of size marks are all manufactured with the same design details and geometry, it is only necessary to carry out the complete test programme on the highest size mark in the range In the event of failure in any of the chairs/tables in the above test programme, it is necessary to carry out the complete test programme on each chair/table size mark individually 3.2 Testing of height adjustable and multi-size chairs and tables Where tables or chairs can be set to a number of different configurations the worst case configuration shall be tested BS EN 1729-2:2012+A1:2015 EN 1729-2:2012+A1:2015 1729-2:2012+A1:2015 (E) (E) EN Where tables and chairs can be adjusted to suit multiple size marks the item shall be assessed in accordance with EN 1729-1 at all size marks, and structural testing shall be carried out at the highest size mark only 3.3 Sequence of testing Testing shall be carried out according to EN 1729-1 prior to testing in EN 1729-2 The tests shall be carried out in the order that the clauses are numbered in this European Standard Safety requirements In order to minimise the risk of personal injury or damage to clothing, the following requirements apply: a) edges of the seat, back rest and arm rests, which are in contact with the user when sitting in the chair shall be rounded with a minimum mm radius or chamfer; b) edges of the handles shall be rounded with a minimum mm radius in the direction of the force applied; c) all other edges and corners with which the user may come into contact with during normal use shall be smooth, rounded or chamfered and shall have no burrs; d) distance between accessible moving parts operated by powered mechanisms, e.g gas lifts, shall always be either < mm or ≥ 25 mm; e) with the exception of setting up or folding tables and chairs, there shall be no accessible gaps > mm and < 25 mm created during normal movements and actions; f) adjustment controls shall not operate inadvertently or accidentally; g) open ends and feet of tubular components shall be capped or otherwise closed; h) parts shall not be detachable without the use of an appropriate tool; i) j) parts which are lubricated shall be covered in order to avoid staining; the finish of the work surface shall not exceed silky matt (corresponding to 45 gloss units or to a 60o reflectometer value of less than 20) to minimise specular reflections in accordance with EN 13722 at 60o; k) chairs shall not overturn when tested as specified in 5.2; l) chairs shall show no structural failure which can affect safety when tested for strength and durability as specified in 5.3 and they shall still fulfil their function For overload tests there shall be no visible fracture or breakage; m) tables shall not overturn when tested in accordance with !EN 1730:2012, 7.2"; n) tables shall show no structural failure which can affect safety when tested for strength and durability as specified in 6.2 and they shall still fulfil its function BS EN 1729-2:2012+A1:2015 EN 1729-2:2012+A1:2015

for educational seating For the purpose of this European Standard, the seat loading point shall be measured forward of the point S (EN 1729-1) and the back loading point shall be measured upwards from a point on the seat vertically below point S NOTE The static loads specified in Clause reproduce the loads applied by adults, who may occasionally sit on small chairs These loads are sufficiently large to make it unnecessary to carry out durability tests on the smaller chair size marks Key BLP Back Load Point SLP Seat Load Point S x y point S point S to seat loading point seat to back loading

thickness of (22 ± 2) mm, with a laminated mat or smooth surface (e.g "velvet" finish) and with edges rounded to a radius of ( +− 10 ) mm A.3 Test method Hang the chair on the test tabletop with the chair placed against the front edge of the test tabletop Apply by means of the pendulum (see !A.2.1") an impact of Nm (31 mm drop height), at a height of 400 mm above the tabletop perpendicular to the back rest of the chair, to the inside surface of the back rest (direction towards the back of the seat) The pendulum shall hit the chair once only With the chair re-placed on the tabletop, repeat the test three times Record if the chair slides off the test tabletop during any of the force applications when tested as specified in !A.3" 24 This page deliberately left blank NO COPYING WITHOUT BSI
