BRITISH STANDARD
National foreword
This British Standard is the UK implementation of
EN 747-1:2012+A1:2015, incorporating corrigendum August 2012. It
supersedes BS EN 747-1:2012, which is withdrawn.
The start and finish of text introduced or altered by amendment is
indicated in the text by tags. Tags indicating changes to CEN text carry
the number of the CEN amendment. For example, text altered by CEN
amendment A1 is indicated by .
BSI, as a member of CEN, is obliged to publish EN 747-1:2012 as a


British Standard. However, attention is drawn to the fact that during
the development of this European Standard, the UK committee voted
against its approval as a European Standard.
NOTE  The UK committee registered a positive vote for the implementation
of CEN amendment A1 June 2015.

WARNING
Users of this British Standard should be aware that the BSI technical
committee responsible for the UK input into EN 747-1:2012+A1:2015 is of
the opinion that entrapment or strangulation hazards might be caused
by the provisions contained in the following clauses:
– Clause
 
4.1.1 (b) that allows for a 600 mm vertical protrusion on the
safety barrier;
– Clause
 
4.1.4 paragraph (7) that allows the outermost components of a
bed to deviate from vertical by 230 mm.
Attention is drawn to the provisions of the General Product Safety
Regulations 2005 which place a general duty on all suppliers of
consumer goods to supply products that are safe in normal or reasonably
foreseeable use.
The UK participation in its preparation was entrusted by Technical
Committee FW/0, Furniture, to Subcommittee FW/0/2, Domestic and
Contract Furniture.
A list of organizations represented on this committee can be obtained
on request to its secretary.
This publication does not purport to include all the necessary provisions
of a contract. Users are responsible for its correct application.

Scope


!This European Standard specifies requirements for the safety, strength and durability of bunk beds and
high beds for domestic and non-domestic use.
It applies to bunk beds with a height to the upper surface of the top bed base of 600 mm or more above the
floor and to high beds with a height to the upper surface of the bed base of 600 mm or more above the floor.
The loads and forces in the strength and durability tests apply to beds with an internal length greater than 140
cm and a maximum bed base width of 120 cm."
The dimensional requirements are intended to minimise the risk of accidents, particularly to children.
The strength and durability requirements are intended to represent use by one occupant per bed.
Safety requirements for other products included in a bunk bed/high bed, for example a table or storage
furniture, are not included in this standard.
This European Standard does not apply to bunk beds and high beds used for special purposes, including but
not limited to prison, the military and fire brigades.

With the exception of the opening for access, the safety barrier shall be designed so that in at least one
direction the clear space between two adjacent retaining elements (e.g. bands, filler bars) is either ≤ 5 mm or
is at least 60 mm and not more than 75 mm when tested in accordance with 5.3 of !EN 7472:2012+A1:2015".
