1 Scope
This European Standard specifies requirements and test methods for storage units (see 3.1) used in
laboratories.
This European Standard specifies strength, durability and safety requirements to prevent serious injury
through normal functional use, as well as misuse that might reasonably be expected to occur.
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 fixing in the wall are not included.
It should be understood that the tests do not ensure that structural 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 ergonomic
aspects or resistance to fire.

4 General test conditions
4.1 Preliminary preparation
The furniture shall be tested as delivered. If of knock-down type, it shall be assembled according 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.
The test unit shall be stored in indoor ambient conditions for at least one week immediately prior to testing.
Any deviation from this procedure shall be stated in the test report.
Except for the deflection of shelves, the tests shall be carried out in indoor ambient conditions, but if during a
test the temperature is outside the range 15 ºC to 25 ºC, the maximum and/or minimum temperature shall be
recorded in the test report.
The tests for the deflection of shelves shall be carried out at a relative humidity of 45 % to 55 %, If during a
test the relative humidity is outside this range, the maximum and/or minimum shall be recorded in the test
report.
Where applicable, units shall be mounted with the fixing points specified by the manufacturer, using fixings
which will not fail during the tests.
Tighten any assembly fittings before testing.
The tests refer to furniture parts with conventional function. Combination of tests may be necessary to cover
the properties of multi-function components, e.g. a shelf that can be pulled out on runners shall be tested for
strength of shelf supports and tested for strength 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. Operation tests shall be carried out sufficiently slowly to ensure that kinetic heating does not occur.
Unless otherwise specified, the test loads may be applied by any suitable device because results are not
dependent upon the apparatus, provided the test equipment does not restrict deformation under load or
tipping except when specifically required.

EN 14727:2005 (E)
4.3 Tolerances
Unless otherwise stated the following tolerances are applicable:
forces  ± 5 % of the nominal force;
velocities ± 5 % of the nominal velocity;
masses  ± 1,0 % of the nominal mass;
dimensions ± 1,0 mm on the nominal dimension;
Angles ±2° of the nominal angle.
The accuracy for the positioning of loading pads shall be ±5;mm.
If masses are used instead of forces, the relationship 10 N = 1 kg shall be used.
4.4 Sequence of testing
All the tests specified for a component, e.g. doors, shall be carried out in the sequence laid down in this
European Standard, but it is not necessary to test the different components of the article e.g. doors or drawers
in the sequence of the clauses.
All tests specified for a component part and/or unit shall be carried out on the same sample.
5 Test apparatus
5.1 Test floor
A rigid, horizontal and flat surface.
5.2 Test wall
A rigid, vertical and plane surface.
5.3 Stops
Stops to prevent the article from sliding but not tilting, not higher than 12 mm except in cases where the
design of the item necessitates the use of higher stops, in which case the lowest that will prevent the item
from sliding shall be used.
5.4 Loading pad
A rigid cylindrical object, 50 mm in diameter, having a flat face with 12 mm radius on the edge.
5.5 Apparatus for slam open of extension elements
Two examples for a suitable apparatus as well as calibration instructions are given in annex A.
5.6 Dead loads
Masses shall be designed so that they do not reinforce the structure or redistribute the stresses.
Bags shall be divided into small compartments to prevent the contents from moving during the test.

---------------------- Page: 9 ----------------------
SIST EN 14727:2006
EN 14727:2005 (E)
5.7 Glass marbles
Marbles between 10 mm and 15 mm in diameter shall be used during the test described in 7.5 (slam open test
of drawers). They shall be in a flexible bag large enough to allow them to move during the test.
5.8 Impact plate
A 1,7 kg impact plate, with a steel plate of 200 mm -109 mm -10 mm faced with a 3 mm thick layer of rubber
with a hardness of (85 ± 10) IRHD according to ISO 7619-2.
6 General safety requirements
Components or parts of the storage units and worktops of storage units with which the user may come into
contact during normal use shall have no burrs and/or sharp edges, nor shall there be open-ended tubes.
To avoid the hazard of a pinching or scissoring action between moving parts accessible during normal use the
distance between such parts shall be kept to less than ≥8 mm or greater than ≥25 mm in any position during
movement, with the exception of doors (including hinges) and extension elements (including runners), but
including the distance between handles and other parts.
In order to avoid pinching points for feet the safety height for vertically moving units shall be at least 100 mm
from the floor.
All 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 any injury.
All extension elements whose mass including contents exceeds 10 kg (see table 1) shall 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 a label on the drawer's front, that the drawer can easily be
pulled out.
2
Any external, vertical glass component ≥0.1 m in area, where the smallest dimension is greater than or equal
to 200 mm and any part of which is less than 900 mm above the floor, shall not break when tested according
to EN 14072, when using a drop height of 60 mm or shall break as specified in EN 14072:2003, clause 7, C2
or C3.
At least two of the wheels or castors of movable units shall be lockable.
If high storage units are equipped with ladders, the ladders shall comply with the relevant requirements of EN
131-2.
The tests specified in clauses 7.1. 1; 7.2; 7.3.2; 7.5.2; 7.6.2; 7.7; 7.8; 8.1 and 8.2 are safety tests.
7 Test procedures and requirements
7.1 Shelves
7.1.1 Stable positioning of shelves
All shelves shall be secured against falling out.
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.
No unloaded shelf shall tip when a downward vertical force of 100 N is applied at any point 25 mm in from the
front edge.

EN 14727:2005 (E)
7.1.2 Deflection of shelves
Testing of the deflection of shelves, which are not made of metal, glass or stone, shall be carried out in a
controlled humidity atmosphere (see 4.1).
Place the shelf on its supports in the unit.
The deflection of the shelf shall be measured at the front edge where it is greatest.
The deflection shall be measured to an accuracy of ±0,1 mm with reference to a straight line parallel to the
front edge drawn between two adjacent supports.
Load the shelf uniformly with the maximum load specified by the manufacturer or within the loads in Table 1
and apply for:
-one hour for shelves made of metal, glass and stove;
-one week for all other shelves.
At the same points as specified above, measure and record the deflection under load to an accuracy of ± 0,1
mm and as a percentage of the distance between the supports.
7.2 Shelf supports
All supports of the shelf for testing shall be tested.
For units with an indeterminate number of shelves, unless otherwise specified, divide the internal height of the
article in millimetres 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 according to table 1.
Table 1 — Required loads
2
Shelves/flaps/bottoms 1,00 kg/dm
3
0,65 kg/dm
Baskets with internal heights ≤ 100 mm
3
All other baskets 0,20 kg/dm
3
0,35 kg/dm
Extension elements with ≤ 110 mm clear height
3
All other drawers 0,20 kg/dm

For the shelf being tested, distribute the load uniformly, except at approximately 220 mm from one support,
where the impact plate (5.8) shall be tipped over 10 times at a point as close to the support as possible (see
Figure 1). The striking surface shall be that faced with rubber.
After the test the shelf supports and/or the shelf/carcase shall show no fracture or other damage that can
affect the safety.
