11、sh Standard has been prepared by Technical Committee CW/52, Childrens cots, bunk beds and mattresses. The types of bedguard covered by this standard are intended for domestic use for children within the age range of 18 months to 5 years. A bedguard used in conjunction with an adult bed is not consid
12、ered a suitable environment for children under 18 months of age. The principal danger from the use of bedguards is perceived to be entrapment should a childs body pass through gaps and then become trapped by the head. In such circumstances there is a real danger that the child could be strangled. Th
13、e entrapment of a limb by the bedguard, although possible in certain circumstances, is thought to be less hazardous, though potentially painful. In particular, attention is drawn to the following Statutory Instruments: Statutory Instrument 1988 No. 1324. The Furniture and Furnishings (Fire) (Safety)
14、 Regulations 1988 1; Statutory Instrument 1989 No. 2358. The Furniture and Furnishings (Fire) (Safety) (Amendment) Regulations 2; Statutory Instrument 1993 No. 207. The Furniture and Furnishings (Fire) (Safety) (Amendment) Regulations 3. A British Standard does not purport to include all the necessa
15、ry provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

17、1 1 Scope This British Standard specifies safety requirements and methods of test for childrens bedguards for domestic use. It applies to bedguards intended for use with beds having a maximum height of 600 mm and a minimum internal length of 1 400 mm. These bedguards, when used in conjunction with a
18、 bed/mattress combination, are intended to prevent children aged between 18 months and 5 years from falling out of bed. This standard is not applicable to bedguards designed for adult use, nor to bedguards which are an integral part of a bed, i.e. a permanent fixture not intended to be detached. 2 N
19、ormative references The following normative documents contain provisions, which, through reference in this text, constitute provisions of this part of this British Standard.

22、ntal member”. 3.2 single-sided bedguard bedguard with a vertical element on one side only, intended to fit against one long side of a mattress 3.3 double-sided bedguard bedguard with a vertical element on both sides, intended to fit against both long sides of a mattress 4 Materials NOTEThe requireme
23、nts of 4.1 and 4.2 do not apply if it is impossible to obtain at least 10 mg of the coating from a single bedguard. 4.1 Plastics Plastics on no part of the bedguard shall contain soluble antimony, arsenic, barium, cadmium, chromium, lead, mercury or selenium, nor any soluble compound of those elemen
24、ts, which exceeds the amounts specified in Table 1, when determined in accordance with BS EN 71-3:1995.

26、, chromium, lead, mercury or selenium, or any soluble compound of those elements, which exceeds the amounts specified in Table 2, when determined in accordance with BS EN 71-3:1995. Where a surface is coated with a multilayer of paint or similar coating, the sample shall be taken down to the substra
27、te. Table 2 Limits of elements in coatings and finishes 4.3 All materials Where different parts of the bedguard are coated with different materials, the coating of each part shall conform to 4.1 and 4.2. 4.4 Wood Wood used in any part of the bedguard shall be free from decay, loose knots and insect
28、infestation. 5 Construction NOTEAnnex A gives tolerances which apply to the tests specified in Annex B, Annex C, Annex D and Annex E. 5.1 General 5.1.1 Exposed edges and protruding parts shall be rounded and/or chamfered as shown in Figure 1a, Figure 1b or Figure 1c, and shall be free of burrs and s
29、harp edges. The edges of sheet materials with a thickness less than 0.5 mm, shall be bent, curled or rolled in at least one of the configurations shown in Figure 1d, Figure 1e or Figure 1f, or shall be covered as shown in Figure 1g. NOTEThe minimum radii shown in Figure 1 do not apply to small compo
30、nents such as hinges, brackets and catches. Hinges, brackets and catches shall be free of burrs and sharp edges.

32、ped. There shall be no openings with a dimension greater than 5 mm and less than 12 mm, unless the depth of possible penetration by a childs finger is less than 10 mm. 5.1.3 The length of the side of the bedguard shall be not less than 900 mm and not more than 1 500 mm. 5.1.4 The height of the bedgu
33、ard shall be not less than 160 mm at any point above the top of the mattress. This dimension shall be calculated using the maximum depth of mattress recommended by the manufacturer. 5.1.5 The distance between the underside of the lowest horizontal member on the vertical face of the bedguard and the
34、underframe of the bedguard shall be not more than 60 mm.

When the bedguard is tested in accordance with Annex B, the 45 mm cone of the slide gauge shall pass freely through the gap without load. The 65 mm cone shall not pass through the gap un
36、der a steady pushing force of 30 N. 5.1.7 When a single-sided bedguard is installed in position in accordance with the manufacturers instructions, the gap between the mattress and the bedguard shall not exceed 40 mm. When a double-sided bedguard is installed in accordance with the manufacturers inst
37、ructions, the total gap between both sides of the bedguard and the edge of the mattress shall not exceed 40 mm. 5.1.8 If the bedguard is covered by a detachable cover, the bedguard shall conform to 5.1.6 when the cover is removed. 5.1.9 When the bedguard is tested in accordance with Annex C, the dis
38、c shall not be supported by any parts of the bedguard. 5.1.10 Any cords, strap or ribbon, including those used for ties, shall have a free length of not more than 220 mm when stretched with a force of 25 N, or shall have a width that is at least half of its length. If cords, straps or ribbons are in

40、lways less than 5 mm. 5.1.12 Monofilament sewing thread shall not be used. 5.1.13 Connecting screws for direct fastening, e.g. self-tapping screws, shall not be used for the assembly of any component that is designed to be removed or loosened when dismantling the bedguard for purposes of transportat
41、ion or storage. 5.1.14 All staples shall be loaded in shear and shall be fully driven home. 5.2 Detachable components Components intended to be removed shall not, whatever their position, fit wholly within the small parts cylinder specified in BS EN 71-1:2001, 8.2. NOTEThis requirement is intended t
42、o prevent the risk of ingestion or inhalation of small objects. 5.3 Non-detachable components Any component which is not intended to be removed shall conform to one of the following. a) The component shall be so embedded that a child cannot grip it with its teeth or fingers. b) The component shall n
43、ot become detached when tested in accordance with BS EN 71-1:2001, 8.3 and 8.4. c) Any components which become detached in accordance with BS EN 71-1:2001, 8.3 and 8.4, shall not fit wholly within the small parts cylinder specified in BS EN 71-1:2001, 8.2. 5.4 Mesh When the mesh is tested in accorda
44、nce with Annex D, the probe shall not pass through the mesh and the threads of the mesh shall not break. 5.5 Security of bedguard After the bedguard has been tested in accordance with Annex E, the gaps in the bedguard shall still conform to 5.1.5 and 5.1.6, and all the locking devices shall remain o

Folding and locking mechanisms shall be considered inoperable by a child if at least one of the following conditions is fulfilled: a) folding or unlocking is only possible when two ind
47、ependent unlocking mechanisms are operated simultaneously; or b) release of the folding or locking mechanism requires a specified minimum force or the use of a tool (e.g. spanner or screwdriver); or c) release of the folding or locking mechanism requires two consecutive actions, the first of which h

49、l engage automatically when the product is deployed for use; or b) when tested with only the automatic locking mechanism(s) engaged, the application of a force of 200 N to any part of the product (except the folding or locking release mechanism) shall not result in hazardous folding or detachment. 5.6.3 Setting-up or folding away 5.6.3.1 There shall be no compression points which can close to less than 18 mm under the action of forces other than those of the carer setting up or folding away (e.g. spring force or gravity), un
