3 General test 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 in the range plus an additional
drop test, seat impact test and 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 plus an additional
impact stability test on the smallest 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 Sequence of testing
The tests shall be carried out in the order the clauses are numbered in this standard.
4 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 2 mm radius;
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;
e) with the exception of setting up or folding tables and chairs, there shall be no accessible gaps ≤ 8 mm or
≥ 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) parts which are lubricated shall be covered in order to avoid staining;
j) reflection of the working surface of tables shall be a maximum 45 ° determined in accordance with EN
13722 at 60 °;
k) tristimulus value of the working surface of tables shall be between 15 % and 75 % determined in
accordance with EN 13721;
l) chairs shall not overturn when tested as specified in 5.2;
m) chairs shall show no structural failure which can affect safety when tested for strength and durability as
specified in 5.3 and it shall still fulfil its function;
n) tables shall not overturn when tested in accordance with 6.7 of EN 1730:2000 and with 6.16 of EN
1728:2000;
o) 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.
5 Testing of chairs
5.1 General
When references are made to EN 1022 or EN 1728, the method of determining the seat and back loading points
specified is not always suitable for educational seating. For the purpose of this 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 5 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.
5.2 Stability
The stability of chairs shall be tested according to EN 1022:2005 but using the loads, forces and loading points
specified in the sub-clauses 5.1.1, 5.1.2 and 5.1.3. B
