The limits for the migration of certain elements are exp

36、ressed in milligram per kilogram toy material and are detailed in Table 2. The purpose of the limits is to minimise childrens exposure to certain potentially toxic elements.

38、kel, selenium, strontium, tin, organic tin and zinc from toy materials and from parts of toys. Packaging materials are not considered to be part of the toy unless they have intended play value. NOTE 1 See guidance document of the European Commission guidance document no. 12 2 on the application of t

39、he Directive on the safety of toys packaging. The standard contains requirements for the migration of certain elements from the following categories of toy materials: Category I: Dry, brittle, powder like or pliable materials; Category II: Liquid or sticky materials; Category III: Scraped-off materi

40、als. The requirements of this standard do not apply to toys or parts of toys which, due to their accessibility, function, volume or mass, clearly exclude any hazard due to sucking, licking or swallowing or prolonged skin contact when the toy or part of toy is used as intended or in a foreseeable way

41、, bearing in mind the behaviour of children. NOTE 2 For the purposes of this standard, for the following toys and parts of toys the likelihood of sucking, licking or swallowing toys is considered significant (see H.2 and H.3): All toys intended to be put in the mouth or to the mouth, cosmetics toys

42、and writing instruments categorised as toys can be considered to be sucked, licked or swallowed; All the accessible parts and components of toys intended for children up to 6 years of age can be considered to come into contact with the mouth. The likelihood of mouth contact with parts of toys intend

43、ed for older children is not considered significant in most cases (see H.2). 2 Normative references The following documents, in whole or in part, are referenced in this document and are necessary for its application.
