This European Standard specifies safety requirements
on the stsucture of built-in and freestanding kitchen
units, work tops and breakîast bars includuig those with glass in their construction
It applies to units after installation This standard does not apply to catering equipment However, safety, depending on the structure of the building, is not included, e.g the strength of wall hanging cabinets includes only the cabinet and its parts The wall and the wall attachment are not included
This standard specifies requirements to prevent serious
MLUY through normal functional use, as well as misuse
that might reasonably be expected to occur
It should be understood that the tests do not ensure that structurai failure will not eventually occur as a
result of habitual misuse or after an excessively long period of service
Assessment of ageing, degradation and the heating effect of appliances are not included nor are the ergonomic aspects of safety and resistance to fire
This European Standard incorporates by dated or undated reference, provisions from other publications
These normative references are cited at the appropriate places in the text and the publications are listed hereafter For dated references, subsequent amendments to or revisions of m y of these publications apply to this European Standard only when incorporated in it by amendment or revision For undated references the latest edition of the publication referred to applies
Determirurtion of hardness (hnrdwss
between 1 O IRHD a,nd 1 O0 IRHD)
For the purposes of this standard the following definitions apply
3.1 free-standing unit
A unit not attached to the structure of the building
3.2 built-in unit
A unit attached to the structure of the building, directly
or via other units

4.1 Preliminary preparation
Before any of the tests are commenced, the item shall have developed its full strength At least four weeks in normal indoor conditions shall have elapsed between manufacturing (or assembly) and testing in the case of glued joints in timber and the like
The furniture shall be tested as delivered If of
knockdown type, it shall be assembled accordmg to instructions supplied with the furniture if the furniture can be assembled or combined in different ways, the most adverse combination shall be used for each test The same is valid for units that can be combined with
other units or components
Units shall be attached at the fixjng points specified by
the manufacturer, using fixings which will not fad during the tests
Any assembly fittings shall be tightened before testing The tests refer to furniture parts with conventional function Combinations of tests may be necessary to cover the properties of multi-function components, e.g a sheif that can be pulled out on runners shall be tested for strength of shelf supports and tested for sîrength of the runners
4.2 Test equipment
The forces in the static load tests shall be applied sufficiently slowly to ensure that dynamic loads are negligible
Unless otherwise specified, the tests may be applied by any suitable device because results are not dependent
upon the apparatus
4.3 Tolerances

forces: +50/0;
velocities: f 5 "/.;
masses: 0,5 "/.;
cimensions 1,0 mm
4.4 Sequence t ' testing
The tests shall be carried out 7 the sequence laid down in this standard
Ail tests specified for a particular part and/or unit shall
be carried out on the same sample

6 Safety requirements 6.1 Principles of safety requirements
The following safety requirements are based upon the knowledge that kitchen units or components are likely
to cause serious ~ u r y onìy when they are heavy and fall through a significant distance
As a consequence, the test methods specified are applicable to all units and components whose centre of
gravity is at or above 900 mm from the floor and whose total mass (in accordance with 7.2) exceeds 10 kg The test methods also apply to
components whose centre of gravity is between 350 mm and 900 mm from the floor and whose
total mass exceeds 35 kg (see annex B)
AIIY external vertical glass components 2 0,i m2 in area, any part of which is less than 900 mm above the floor shall fulfil the requirements according to 8.9
or 8.10
6.2 Constructional safety requirements
Components or parts of the kitchen units and worktops with which the user may come into contact during normal use shall have no buns andor sharp
edges, ilor shall there be open-ended tubes
To avoid the haz
between accessibit moving parts during n o d use
the safety distance between such parts shall be kept
to 5 8 mm or 2 25 mm in any position during movement, with the exception of doors and extension elements, but including handles
in order to avoid pinching points for feet the safety distance shall be 2 100 mm
Ail roll front doors sliding vertically shall not move by themselves from any position higher than 50 mm
measured from the closed position if this can cause
of a pinching or scissoring action
any W W
Units intended for storage of hazardous items or substances shall, when locked, not be opened by a force of 5 200 N applied directly to the handle
AU drawers whose total mass (in accordance with 7.2)
exceeds 10 kg but where safety tests are not carried
out (see clause 7) should have effective open stops,
i.e they shall resist being pulled out of the carcase once by a force of 200 N applied to the handle of the
loaded drawer or they shall be supplied with product informatioii to the effect that drawers can easily be pulled out
Additional requirements are specified for strength of work tops and stability of free standing units (see 8.7
and 9)
7 Tkst parameters 7.1 Determination of the centre of gravity The centre of gravii, of a component or unit shall be taken as the geometric centre of the usable volume of
drawers and cupboards and as the geometric centre of
doors, flaps and shelves
The height of the centre of gravity above the floor s h d
be measured for floor units or their components when installed according to the manufacturer’s inStnictions
Adjustable feet shall be set at their middle position
Height aaustable components of floor units shall be placed in their highest position
AU work-tops and wall or topmounted units or components thereof are considered to have their centre of gravity more than 900 mm above the floor, unless restrictions are stated by the manufacturer
7 Determination of total mass
Tii iotaì mass shall be the mass of the component or
unit plus the mass supported by it

Unless conspicuously and durably marked by the
manufacturer with a maximum allowable load, the
mas supported shall be determined according
to table 1, which specifies the load per unit area for
shelves, -pS and bottoms and the load per unit
volume for drawers and baskets
The volume of baskets shall be taken as the volume
contained below the top edge
The volume of drawers shall be taken as the area of
the drawer bottom multiplied by the clear height
NOTE The clear height is the maximum clear distance over the
drawer bottom This is often the distance from the top of the
drawer bottom to the lower edge of the drawer front of the
drawer above, or the structure of the unit

8 l è s t procedures and requirements
8.1 Shelves
Shelves more than 900 mm above the floor shall be
secured against falling out
If the shelf is not restmined by a physical stop, this
requirement is fulfilled when the horizontal force
applied to the middle of the front edge required to
initiate movement of the unloaded shelf is more
than 50 % of the weight of the unloaded shelf
Any unloaded shelf shail not tip when a downward
vertical force of 100 N is applied at any point 25 mm in
from the front edge
8.2 Shelf supports
Ail supports of the tested shelf shall be tested
For units with an indeterminate number of shelves, unless otherwise specified, àivide the internal height of
the unit in milhetres by 300 and take the nearer integer This number minus 1 shall then be the number
of shelves to be fitted Load all components intended for storage purposes uniformly in accordance with table 1
For the shelf being tested, distribute the load
uniformly, except at approximately 220 mm from one support, where the impact plate (6.8) shall be tipped over 10 times at a point as close to the support as
possible (see figure 3) The striking surface shall be that faced with rubber
After the test the shelf supports and/or the sheWcarcase shall show no fracture or other damage that can affect safe@
8.3 Pivoted doors
This test applies to a l l doors hinged to the carcase on one vertical side (including folding doors)
Load ail components intended for storage purposes uniformly in accordance with table 1
Load the door as shown in figure 4 with a load
of 30 kg
Swing the door 10 full cycles (back and forth) from a
position 45" f 2" from fully closed to a position 10" f 2" from fully opened, but to a maximum of 135"
Opening and closing can be done by hand using 3 s to
5 s for opening and 3 s to 5 s for closing
After the test the door shall remain attached to the cabinet
