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

Introduction
This part of EN 747 specifies requirements for bunk beds and high beds for use by one occupant per bed
Trang 7Introduction
This part of EN 747 specifies requirements for bunk beds and high beds for use by one occupant per bed
1 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
