4 General test conditions
4.1 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, plus additional stability tests on the smallest size mark in the range.

Safety requirements for chairs and tables as specified in Clause 4 shall be assessed for all size marks in

the range. Additional safety requirements as specified in Annex A shall be assessed for all size marks 0 to

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.

If a chair is adjustable between two sizemarks (i.e. sizemark 3 and 5), largest sizemark (i.e. sizemark 5)

shall be fully tested and the smallest sizemark (i.e. sizemark 3) shall only be tested for stability.

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.
4.2 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.

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.
4.3 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 document.
5 Safety requirements
5.1 General safety requirements

In order to minimize 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 2 mm radius or chamfer;

b) edges of the handles shall be rounded with a minimum 2 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 < 8 mm or ≥ 25 mm;

NOTE for commenting: This requirement conflicts with the requirement in 5.2 b) for chairs sizemarks 0

to 3.

e) with the exception of setting up or folding tables and chairs, there shall be no accessible gaps > 8 mm

and < 25 mm created during normal movements and actions;

f) adjustment controls shall not operate inadvertently or accidentally;

g) when accessible to the user under normal use, 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) chairs shall not overturn when tested as specified in 6.2;

j) chairs shall show no structural failure which can affect safety when tested for strength and durability

as specified in 6.3 and they shall still fulfil their function. For overload tests there shall be no visible

fracture or breakage;
k) tables shall not overturn when tested as specified in 7.1 of this document;

l) tables shall show no structural failure which can affect safety when tested for strength and durability

as specified in 7.2 and they shall still fulfil its function.
