Atten

24、tion is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes CEN/TR 13387:2004. CEN/TR 13387 comprises the following five parts

25、: Part 1: Safety philosophy and safety assessment Part 2: Chemical hazards Part 3: Mechanical hazards Part 4: Thermal hazards Part 5: Product information CEN/TR 13387-3 should be used in conjunction with CEN/TR 13387-1. This new edition of this Technical Report is a hazard based Technical Report. In

26、 comparison with the previous version, the main changes related to the section on Mechanical hazards are: Ageing and wear: Reworded; Accessibility of mechanical hazards: Reworded; Entrapment Hazards: Addition of a new finger probe and a hip probe; Hazards from moving parts: Moving parts separated in

27、to two main areas; Entanglement hazards: Improvement of the diagram for the ball and chain test; clarification of the clause for “Cords, ribbons and parts used as ties; Suffocation hazards: Clarification of the clause for “Non air-permeable packaging”; Hazardous edges and projections: Drawings delet

28、ed; Protective function: Addition of a hip probe; Footholds: Reworded. PD CEN/TR 13387-3:2015 CEN/TR 13387-3:2015 (E) 6 1 Scope This Technical Report provides guidance information on mechnical hazards that should be taken into consideration when developing safety standards for child use and care art

29、icles. In addition, these guidelines can assist those with a general professional interest in child safety. 2 Mechanical hazards - Safety philosophy This clause addresses the most widely known mechanical hazards and is intended to provide guidance when drafting standards for child use and care artic

30、les. Anthropometric data and information on the abilities of children related to risks are given in Annex A of CEN/TR 13387-1:2015. When using these data for setting requirements, adequate safety margins should be considered. These data refer to static and not dynamic anthropometric data, therefore

31、care should be taken if using these data for anything other than static situations when drafting standards. When drafting standards, conditions of use should be considered, bearing in mind the behaviour of children. Also, it is to be considered whether the child is attended or unattended when using

32、the product and also the childs access to hazardous features. For each mechanical hazard a rationale is given, explaining the potential hazard to the child. Requirements, test equipment and test methods are also given. Where appropriate, these can be used when drafting standards. 3 Terms and definit

33、ions For the purposes of this document, the following terms and definitions related to mechanical hazards apply. 3.1 mechanical hazards physical factors which may give rise to injury due to the mechanical properties of products/product parts 3.2 reach envelopes age related physical data on the reach

34、 limits of the limbs of children in different postures, see 4.2 3.3 ageing change of properties of the material due to exposure to environmental factors such as temperature, humidity, UV radiation, cleaning agents etc 3.4 mechanical wear change of mechanical properties due to fatigue or repeated ope

35、ration of devices, mechanisms and other parts of the product 4 Accessibility of mechanical hazards 4.1 General Within the mechanical section no reference is made to specific areas of access, known as access zones. It would be wrong for this guidance document to specify exact areas of access as these

36、 should be determined in relation to the hazards and risks of individual products and risks when drafting the standard. As a general guidance to the types of contact associated with mechanical hazards, the following examples are given: PD CEN/TR 13387-3:2015 CEN/TR 13387-3:2015 (E) 7 the hazardous p

37、art is in reach of the child from the intended position of use in particular by head, mouth, hands or feet and there is a high probability for frequent, intensive and/or prolonged contact. Requirements need to address this primary contact; the hazardous part may be reached by the child or any other

38、child beyond the intended position of use. The product is considered to remain in its intended position(s). Access to hazardous parts is gained by passing/moving around the product or when proceeding to the intended position. The risk of harm deriving from frequent, intensive and/or pro-longed conta

39、ct may be less probable; the hazardous part exists, but cannot be reached by any child. Irrespective of the access category, the reasonably foreseeable conditions of use should always be considered when designing childrens products and/or writing product standards. 4.2 Accessibility areas Informatio

40、n for determination of accessibility areas in connection with age group is given in Table 1 and Figure 1. These reach envelopes are based on a computer simulation, therefore the dimensions should be treated with care. If in the future experiments with children are undertaken, these figures in the ta

41、ble may be determined more accurately.

44、ng Figure 1 Reach envelopes for determination of accessibility areas 4.3 Product information In order to ensure mechanical safety, the information for the carer should include appropriate instructions and warnings. For example: the need for restraint system and its adjustment; the opening and closin

45、g of products; the operation of safety locks for foldable parts; the method of attachment to fixed structures or to other products. Instructions should also inform the carer of the need to inspect the product regularly and also to use only replacement parts that are approved by the manufacturer/supp

PD CEN/TR 13387-3:2015 CEN/TR 13387-3:2015 (E) 9 CEN/TR 13387-5:2015 “Product information“ gives detailed advice concerning the presentation of product information. 5 Entrapment hazards 5.1 Introduction To avoid entrapment of head, neck, fingers, feet, and hands, safety distances are recommend

47、ed in relation to the anthropometric data (see Annex A of CEN/TR 13387-1:2015) of the growing child. It is important to take into account the intended age and/or development level of the child. As a priority, those parts of a product which are accessible when a child is using the product as foreseea

48、ble should be considered. It may also be appropriate for gaps and openings beyond these accessible areas to be addressed. Gaps and openings which are inaccessible need not to be considered. However, V-shaped openings or V-shaped arrangements of structural members should be avoided. Important entrapm

49、ent hazards are: entrapment of the neck in situations where the child is incapable of raising its body weight to relieve the pressure (e.g.: crawling child on the outside of play pen, V shapes, etc.); entrapment of the neck in situations where the child slips through a gap feet first (e.g.: child slipping between bars/slats); entrapment of fingers, which may cause loss of blood supply to the tips. If it is possible to position a child use and care article next to other furniture or a wall and create an entrapment hazard be
