BS EN 747-1:2012+A1:2015EN 747-1:2012+A1:2015 (E) 4 Introduction This part of EN 747 specifies requirements for bunk beds and high beds for use by one occupant per bed. EN 747-1:2012+A1:2015 (E)
27、5 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 heig
28、ht 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 ac
29、cidents, 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 Standa
30、rd does not apply to bunk beds and high beds used for special purposes, including but not limited to prison, the military and fire brigades. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

37、0 mm or more (see Figure 1), have a maximum height at which a line, drawn at 45 touches it, of not more than 5 mm above at least one adjacent/adjoining horizontal component; the maximum vertical protrusion above that component shall not exceed 20 % of the largest horizontal dimension of parts (see F
38、igure 1 c), or d) where the largest dimension is less than 50 mm, have a maximum height at which a line, drawn at 45 touches it, of not more than 5 mm above at least one adjacent/adjoining horizontal component; the maximum vertical protrusion above that component shall not exceed 10 mm (see Figure 1
