part 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
castors
assembly comprising a housing, one or more wheels and at least one axes
3.3
leg rest
extension of the seat area intended to support the legs of the sitter
Note 1 to entry: A leg rest may or may not be permanently attached to the seat. Some leg rests may not be
designed to support the load of the user.
3.4
footrest
component intended as an occasional support for the feet or to assist getting on and off an item of seating
Note 1 to entry: A footrest may be a part of the structure of the underframe of a chair or stool.
3.5
visitor chair
seating for one person used in the office environment additional to the office work chair
Note 1 to entry: It is used for meetings or collaborative work as well as for reading, writing, listening and waiting.
3.6
single column seating
item of seating whose upper part, which includes the seat, is mounted on a single support with a
dimension of up to 120 mm at its narrowest point
Note 1 to entry: This includes e.g. chairs with gas lifts and with or without swivel function.
3.7

4 Safety, strength and durability
4.1 General requirements
The seating shall be designed so as to minimize 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:
a) edges and corners of the seating which are directly in contact with the user are rounded or
chamfered;
b) all other edges and corners accessible during intended use are free from burrs and/or sharp edges.
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.
For non-domestic chairs, see Annex G (Informative) that contains recommended dimensions for non-
domestic chairs.
4.2 Holes and tubular/rigid components
There shall be no holes in the ends of tubular components or holes in rigid components in accessible parts
between 8 mm and 12 mm, unless the depth of penetration is less than 10 mm. This requirement is
fulfilled if there is no hazard present when tested in accordance with A.1.
4.3 Shear and compression points
4.3.1 General
The requirements contained within 4.3.2, 4.3.3 and 4.3.4 do not apply to electrically operated furniture.
NOTE The requirements for electrically operated furniture will be provided in EN 17684 which is under
preparation.
4.3.2 Shear and compression points when setting up and folding
Unless 4.3.3 or 4.3.4 are applicable, shear and compression points that are created only during setting up
and folding are acceptable, because the user can be assumed to be in control of his/her movements and
to be able to cease applying the force immediately upon experiencing pain.
The edges of parts moving relative to each other and creating shear and compression points shall be as
specified in 4.1.
4.3.3 Shear and compression points under influence of non-electrically powered mechanisms
With the exception of operation of doors, flaps, lids and extension elements, there shall be no areas where
the distance between two accessible parts moving relative to each other can be less than 25 mm, and
more than 8 mm in any position during movement that could present a risk of injury to the user, created
by parts of the furniture operated by powered mechanisms, e.g. mechanical springs and gas lifts.
This requirement is fulfilled if there is no hazard present when tested in accordance with A.2.2.
NOTE Further guidance of the accessible parts is given in CEN/TR 17202.
4.3.4 Shear and compression points during use
With the exception of operation of doors, flaps, lids and extension elements, there shall be no areas where
the distance between two accessible parts moving relative to each other can be less than 18 mm, and
more than 8 mm in any position that could present a risk of injury to the user, created by loads applied
during normal use.
The loads used for durability tests within Table 1 are considered representative of normal use.
This requirement is fulfilled if there is no hazard present when tested in accordance with A.2.3.
4.4 Stability
The seating shall fulfil the relevant requirements of EN 1022 after having completed the relevant tests
listed in Table 1.
4.5 Strength and durability
4.5.1 Test methods
Seating shall be tested on the same sample for safety, strength and durability according to and in the
order given in Table 1 and in accordance with the test conditions contained in EN 1728:2012.
Seating with a seat and back made of one piece of flexible material suspended in the upper part of the
backrest and the front of the seat shall be tested according to Annex D. For this type of seating, only the
tests on seat shall be carried out.
The following tests described in Table 1 are considered to be relevant for safety.
Test No.: 1, 2, 4.1, 4.2, 6, 7.1, 7.2, 8, 9, 10, 11, 12, 13, 14, 15, 16.
Annex E (Informative) contains additional drop tests
The guidance for selecting level L1 or L2 with due respect for the end use of the product is given
in Annex F.
Annex H (Informative) contains a rationale for single column seating.
