For this r

21、BS EN 747-1:2007 EN 747-1:2007 (E) 5 1 Scope This European Standard specifies requirements for the safety, strength and durability of bunk beds and high beds for domestic use. The loads and forces in the strength and durability tests apply to beds with a maximum bed base width of 120 cm. It is parti
22、cularly intended to minimise the risk of accidents happening to children. If the bunk bed/high bed includes other products, for example a table or storage furniture, the safety requirements for these products are not covered by this standard. 2 Normative references The following referenced documents

28、ent shall not exceed 10 mm (see Figure 1). Dimension in millimetres Key 1 Bedpost Figure 1 Example of a vertically protruding part 4.3 Safety barriers Any bed where the height of the upper surface of the bed base is 800 mm or more above the floor shall be equipped with safety barriers all around the
29、 bed. The safety barriers shall be secured against unintentional loosening. This requirement is fulfilled if the safety barriers do not become damaged or loosened when tested in accordance with 5.4.2 of EN 747-2:2007. It shall not be possible to remove the barriers without the use of a tool. The dis
30、tance between the upper edge of the safety barriers and the upper surface of the bed base shall be at least 260 mm. The top of the mattress shall be at least 160 mm below the upper edge of the safety barriers. The maximum thickness of the mattress shall be permanently marked, see clause 5 d) and cla

With the exception of the upper corners of the safety barrier, which may end in a maximum radius of 85 mm, the opening for access shall have a width between 300 mm and 400 mm from the maximum mattress thickness mark (see clause 6 b) to 160 mm above it (see Figure 2).
