33、 conditions 3.1 Testing ranges of 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, plu
34、s 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
35、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
36、 case configuration shall be tested.

37、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. 4 Safety requirements In order to minimise the risk of personal injury or damage to cl
38、othing, 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 2 mm radius or chamfer; b) edges of the handles shall be rounded with a minimum 2 mm radius in the direction of the fo
39、rce 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 8 mm and 1 00

45、sary to test their resistance to falling off tables. This applies only size mark 3, 4, 5, 6 and 7 chairs. Such chairs can be tested in accordance with the test method specified below in !A.3“. A.2 Test equipment A.2.1 An impact hammer as specified in !EN 1728:2012, 5.10“. A.2.2 A tabletop, with a th
46、ickness of (22 2) mm, with a laminated mat or smooth surface (e.g. “velvet“ finish) and with edges rounded to a radius of (102+) 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
47、impact of 2 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“. DIN EN 1729-2:2016-03
