The relationship 10 N = 1 kg should be used. — Velocities: ± 5 % of the nominal velocity; — Masses: ± 1 % of the nominal mass; — Dimensions: ± 1 mm of the nominal dimension; — Angles: ± 2° of the nominal angle. NOTE For the purposes of uncertainty measurement, test results are not considered to be adversely affected when the above tolerances are met. 5 Safety requirements 5.1 Principles of safety requirements 5.1.1 General The safety requirements are based upon the knowledge that kitchen units, bathroom units and domestic storage furniture and their components are likely to cause serious injury only when they are heavy and fall through a significant distance. This is possible if floor standing units overturn, wall or screen hanging units become detached, or heavy components become detached from units. 5.1.2 Determination of centre of gravity The centre of gravity above the floor (for floor standing units) shall be measured when installed according to the manufacturer's instructions. Levelling devices shall be set at their middle position. Height adjustable components shall be placed in their highest position. The centre of gravity of a component or unit shall be taken as the geometric centre of that unit, except in the case of extension elements, where the geometric centre of the usable volume shall be used. All wall hanging units or top hanging units or components thereof are considered to have their centre of gravity more than 900 mm above the floor. SIST EN 14749:2016
EN 14749:2016 (E) 10 5.1.3 Determination of total mass The total mass is the mass of the component or unit plus the mass determined according to Table 1, unless the unit or component is conspicuously and durably marked by the manufacturer with a maximum load, in which case the unit or component shall be loaded with the stated maximum load multiplied by 1,2. The volume of fixed baskets shall be taken as the volume contained below their top edge. The volume of extension elements shall be taken as the area of its bottom multiplied by the clear height. Table 1 — Loads Component Load All horizontal storage areas, including shelves, bottoms, tops and bottom hinged flaps 0,65 kg/dm2 Extension elements and fixed baskets 0,2 kg/dm3 Clothes rails 4,0 kg/dm Suspended filing pockets 2,5 kg/dm a Storage area/-volume (3.10) for heavy appliances (e.g. refrigerator, washing machine)b 0,5 kg/dm3 c a Measured perpendicular to the plane of the filing pockets. b Other heavy objects, e.g. aquariums are not covered by this value. c Max. load 200 kg per unit. 5.2 General safety requirements 5.2.1 General The following requirements apply to all units and components. Components with which the user can come into contact during normal use shall have no burrs and/or sharp edges, nor shall there be any open-ended tubes. All movable components accessible during normal use shall have safety distances in any position during movement of
¶ 8 mm or
· 25 mm. This applies to any components moving relatively to each other, with the exception of doors, flaps and extension elements including their hardware. The safety distances also apply to the distance between handles/handgrips and other components. 5.2.2 Units moving vertically In order to avoid pinching points for feet, the safety height for units moving vertically shall be at least 100 mm from the floor. 5.2.3 Lids In order to prevent children's heads and necks from being entrapped by hinged lids of storage units horizontal lids that are 1 000 mm or less from the floor and weigh 0,25 kg or more, shall be provided with lid-support mechanisms to prevent sudden collapse or dropping of the lid. The lid-support mechanism shall support the lid so that at no position in the arc of travel of the lid from within 50 mm of the fully closed position through an arc not to exceed 60° from the fully closed position shall it drop more than 12 mm under the influence of its own mass, except in the last 50 mm of travel. The test shall be carried out in accordance with EN 71-1:2014, 8.31.2. In the case of adjustable mechanisms, product information shall be given for the correct adjustment. SIST EN 14749:2016
EN 14749:2016 (E) 11 5.2.4 Vertically moving roll fronts and vertically moving sliding doors All roll fronts and doors sliding vertically including those constructed from hinged components shall not move by themselves from any position higher than 200 mm measured from the closed position. 5.2.5 Extension elements All extension elements whose total mass (according to 5.1.3) exceeds 10 kg but where safety tests are not required shall have effective open stops, i.e. they shall resist being pulled out of the unit once by a horizontal force of 200 N applied to the handle of the loaded extension element (according to Table 1), or they shall be supplied with product information to this effect. 5.3 Structural safety requirements 5.3.1 General The tests and requirements in 5.3.2 to 5.3.9 apply to any component only when: — the height to the centre of gravity of the component is > 900 mm above the floor and the total mass (5.1.3) is ≥ 10 kg; or — the height to the centre of gravity of the component is > 350 mm and the total mass (5.1.3) is
· 35 kg. Where specified in EN 16122, storage units and their components shall be loaded in accordance with Table 1. Unless otherwise specified, all storage components, which are not subject to testing, shall be uniformly loaded with the specified load(s). When the unit or component is conspicuously and durably marked by the manufacturer with a maximum load, the unit or component shall be loaded with the stated maximum load multiplied by 1,2. Details on testing and application of safety requirements can be found in Annex B (informative). 5.3.2 Shelves 5.3.2.1 Shelf retention – vertical downward Unloaded shelves shall not fall down when tested according to EN 16122:2012, 6.1.3 with a downwards vertical force of 100 N. 5.3.2.2 Shelf retention – horizontal outward Unloaded shelves shall not fall down when tested according to EN 16122:2012, 6.1.2 with a force representing 50 % of the weight of the unloaded shelf. 5.3.3 Shelf supports If the clear height is less than 200 mm the test is not carried out. This test shall be carried out according to EN 16122:2012, 6.1.5 with impact plate No. One on all horizontal surfaces e.g. shelves, tops and bottoms that can be used as storage area.

Introduction
This European Standard is the result of the revision of EN 14749:2005, which was a merged standard out of
the previous and withdrawn:
EN 1727:1998, Domestic furniture — Storage furniture — Safety requirements and test methods, and
EN 1153:1995, Kitchen furniture — Safety requirements and test methods for built-in and free standing
kitchen cabinets and worktops.
With this revision the included test methods have been as far as possible taken out of this European Standard
and referenced to:
EN 16122:2012, Domestic and non-domestic storage furniture — Test methods for the determination of
strength, durability and stability.
This European Standard was prepared in order to provide assurance that domestic storage furniture and
kitchen-worktops comply with the given requirements and are reasonably safe.
Note that the assessment of ageing and degradation of materials and the effects caused by heating from
appliances are not included, nor is fire safety.
The intention of this European Standard is the prevention of serious injury through normal use, as well as
foreseeable misuse. It cannot ensure that structural failure will not eventually occur as a result of habitual
misuse.
Co-ordinating sizes for kitchen furniture (including kitchen-worktops) kitchen appliances, sinks and decorative
panels are covered by EN 1116, Kitchen furniture — Co-ordinating sizes for kitchen furniture and kitchen
appliances.

1 Scope
This European Standard specifies safety requirements for all types of kitchen and bathroom storage units and
domestic storage furniture that are fully assembled and ready for use, including kitchen-worktops and movable
and non-movable components and components made of glass.
It specifies additional test methods in Annex A (normative).
It does not apply to non-domestic storage, office storage, industrial storage, catering equipment, retail storage
and industrial storage lockers.
It does not apply to units covered by EN 71-1, Safety of toys – Part 1: Mechanical and physical properties and
EN 60065, Audio, video and similar electronic apparatus – Safety requirements.
It does not include requirements for electrical safety.
If the furniture has additional functions, it is essential that it also meets the safety requirements of the
appropriate European safety standard for that function.
Safety depending on the structure of the building is not included, e.g. the strength of wall hanging units
includes only the cabinet and its components. The wall and the wall attachments are not included.
This European Standard does not include requirements for the resistance to ageing, degradation and
flammability.
Annex A (normative) contains additional test methods.
Annex B (normative) contains a guideline for testing according to this document.
Annex C (informative) contains an example of loading of wall hanging units.
Annex D (informative) contains the relation between safety requirements, total mass and position of centre of
gravity.

4.3 Tolerances (allowed variation from the nominal values)
Unless otherwise stated, the following tolerances are applicable:
Forces: ± 5 % of the nominal force;
NOTE 1 The forces is replaced by masses. The relationship 10 N = 1 kg is used.
Velocities: ± 5 % of the nominal velocity;
Masses: ± 1 % of the nominal mass;
Dimensions: ± 1 mm of the nominal dimension;
Angles: ± 2° of the nominal angle.
NOTE 2 For the purposes of uncertainty measurement, test results are not considered to be adversely affected when
the above tolerances are met.
5 Safety requirements
5.1 Principles of safety requirements
5.1.1 General
The safety requirements are based upon the knowledge that kitchen units and domestic storage furniture and
their components are likely to cause serious injury only when they are heavy and fall through a significant
distance. This is possible if floor standing units overbalance, wall or screen hanging units become detached,
or heavy components become detached from units.
Therefore, with the exception of stability (5.4), vertical glass components (5.5) and TV-furniture (5.4.3), the
requirements specified in 5.3 are only considered to affect safety when:
the height of the centre of gravity of the unit, or any component, is > 900 mm above the floor and the total
mass is > 10 kg;
or
the height of the centre of gravity is above 350 mm and whose total mass (according to 5.1.3) is equal to
or exceeds 35 kg.
NOTE Values to be approved during CEN-enquiry.
The tests in 5.3.12 shall be carried out on all wall and top hanging units with a total mass equal to or more
than 10 kg. All components in wall and top hanging units shall be tested irrespective of their total mass.
However, the safety requirements specified in 5.3 do not apply to components with a total mass less than
10 kg, see 5.3.12.2.
The requirements for stability (5.4) only apply to storage units where the height to the top of the unit is
600 mm or more above the floor level, and when the potential energy (3.12), exceeds 60 Nm.
5.1.2 Determination of centre of gravity
The centre of gravity of a component or unit shall be taken as the geometric centre of that unit, except in the
case of extension elements, where the geometric centre of the usable volume shall be used.
The height of the centre of gravity above the floor (for floor standing units) shall be measured when installed
according to the manufacturer's instructions.

---------------------- Page: 11 ----------------------
oSIST prEN 14749:2013
prEN 14749:2013 (E)
All wall or top hanging units or components thereof are considered to have their centre of gravity more than
900 mm above the floor.
Levelling devices shall be set at their middle position.
Height adjustable components shall be placed in their highest position.
5.1.3 Determination of total mass
The total mass is the mass of the component or unit plus the mass determined according to Table 1.
When a component is conspicuously and durably marked by the manufacturer with a maximum load, this load
shall be used to determine the total mass.
The volume of fixed baskets shall be taken as the volume contained below their top edge.
The volume of extension elements shall be taken as the area of its bottom multiplied by the clear height.

the stated maximum load multiplied by 1,2
5.2 General safety requirements
5.2.1 General
The following requirements apply to all units and components regardless of the safety principles (5.1).
Components with which the user may come into contact during normal use shall have no burrs and/or sharp
edges, nor shall there be any open-ended tubes.
All movable components accessible during normal use shall have safety distances in any position during
movement of ≤ 8 mm or ≥ 25 mm. This applies to any components moving relatively to each other, with the
exception of doors, flaps and extension elements including their hardware. The safety distances also apply to
the distance between handles/handgrips and other components.
5.2.2 Vertical moving units
In order to avoid pinching points for feet, the safety height for vertically moving units shall be at least 100 mm
from the floor.

5.2.3 Lids
In order to prevent children's heads and necks from being entrapped by hinged lids of storage units horizontal
lids that are 1 000 mm or less from the floor and weigh 0,25 kg or more, shall be provided with lid-support
mechanisms to prevent sudden collapse or dropping of the lid. The lid-support mechanism shall support the lid
so that at no position in the arc of travel of the lid from within 50 mm of the fully closed position through an arc
not to exceed 60° from the fully closed position shall it drop more than 12 mm under the influence of its own
mass, except in the last 50 mm of travel.
The test shall be carried out in accordance with EN 71-1:2011, 8.31.2. In the case of adjustable mechanisms,
product information shall be given for the correct adjustment.
5.3 Structural safety requirements
5.3.1 General
The requirements in 5.3 apply only to units and components, which fall under the principles in 5.1.
