24、re unable to sit up unaided. This standard applies also to car seats complying with ECE 44 that can be used as reclined cradles according to manufacturers instructions. This standard does not apply to reclined cradles when used as swings. If a reclined cradle has several functions or can be converte

25、d into another function the relevant European standards apply to it (see Annex B). 2 Normative references The following referenced documents are indispensable for the application of this document.

34、 content not exceeding the following values: Antimony: 60 mg/kg; Arsenic: 25 mg/kg; Barium: 1 000 mg/kg; Cadmium: 75 mg/kg; Chromium: 60 mg/kg; Lead: 90 mg/kg; Mercury: 60 mg/kg; Selenium: 500 mg/kg. The test procedure is defined in EN 71-3. Where a surface is coated with a multi-layer of paint or s

35、imilar coating, the test sample shall not include any of the base material. 4.2 Flammability There shall be no parts of the reclined cradle which can give rise to surface flash, when tested in accordance with EN 1103. BS EN 12790:2009EN 12790:2009 (E) 8 5 Construction 5.1 Shrinkage After cleaning an

36、d drying twice in accordance with the manufacturers instructions, any resulting shrinkage in the fabric covering materials shall not prevent removable fabrics from being refitted. 5.2 Finger entrapment When tested in accordance with 6.3 there shall be no holes, openings or gaps greater than 7 mm and

37、 less than 12 mm unless the depth of penetration of the appropriate probe is less than 10 mm on the inner and upper surface which supports the child. The test shall be carried out with the product in any intended position of use. Restraint systems are excluded from this requirement. 5.3 Moving parts

38、 To avoid the risk of shearing and crushing once the reclined cradle is assembled for normal use the distance between two parts which move relative to each other shall be less than 5 mm or more than 12 mm throughout the entire movement. Moving parts can arise from: a) the movement of the reclined cr

39、adle; b) the movement of the body weight or action of the child using the reclined cradle; c) a powered mechanism. Locking mechanisms and the base of the article and its functional parts for rocking and bouncing are excluded from this requirement. 5.4 Edges, points and corners All accessible edges,

40、corners and protruding parts on the reclined cradles inner and upper surface which supports the child shall be rounded or chamfered and free from burrs. All surfaces shall be free from burrs and sharp edges. 5.5 Small parts When tested in accordance with 6.4, any part that can be detached shall not

41、fit wholly within the small parts cylinder. Parts intended to be removed shall not fit wholly within the small parts cylinder. 5.6 Cords, ribbons and parts used as ties Cords, ribbons and parts used as ties excluding restraint system shall have a maximum free length of 220 mm when stretched by a for

42、ce of 25 N. 5.7 Springs If the reclined cradle is fitted with springs, a protection is required when the space between two helical coils can become equal to or greater than 3 mm and smaller than 12 mm, when tested in accordance with 6.5. BS EN 12790:2009EN 12790:2009 (E) 9 5.8 Locking mechanism(s) f

43、or folding system 5.8.1 General Reclined cradles which may be folded for storage or transportation purposes shall be fitted with locking mechanism(s) for the folding system. Locking mechanism(s) is required to prevent a reclined cradle folding whilst the child is in the cradle and also during the pr

44、ocess of a child being put in and taken out of the cradle. 5.8.2 Incomplete deployment To avoid the hazard due to incomplete deployment, at least one locking mechanism shall engage automatically when the product is deployed for use in accordance with the manufacturers instructions for use. When test

45、ed in accordance with 6.6.1 the reclined cradle, with the non automatic locking mechanism(s) not fully engaged, shall not collapse or tip over. 5.8.3 Unintentional release of locking mechanism(s) To avoid the hazards due to unintentional release, one of the following conditions shall be fulfilled: a

46、) at least one locking mechanism requires an operating force greater than 50 N before and after testing in accordance with 6.6.3, or b) at least one locking mechanism is released by the use of a tool, or c) folding requires at least two consecutive actions, the first of which must be maintained whil

47、e the second is carried out, or d) folding requires at least two independent and simultaneous actions. When tested in accordance with 6.6.2, the reclined cradle shall not collapse. 5.9 Reclining system Any adjustment mechanism(s) for the reclining system shall not be positioned on the inner and uppe

48、r surface which supports the child. Reclined cradles with adjustable backrest or seat angle shall be fitted with a stop at the maximum reclined position to avoid inadvertent contact between the seat unit and the ground or any rigid part of the frame during testing in accordance with 6.7. The reclining system shall still function after testing in accordance with 6.7. During testing in accordance with 6.7, angles and distance H of the reclined cradle shall still satisfy the requirements of 5.10. 5.10 Angle and height
