This Eur

19、opean Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2006, and conflicting national standards shall be withdrawn at the latest by June 2006. This European Standard has been prepared under a mandate given

20、to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this European Standard. This European Standard constitutes part 10 of the E

21、uropean Standard on Safety of Toys. This part should be read in conjunction with parts 9 and 11. This European Standard defines the sample preparation and extraction procedures used to address potential exposure to organic compounds from ingestion, mouthing, inhalation, skin contact with solids and

22、skin and eye contact with liquids. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary,

23、Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 71-10:2005 (E) 4 Introduction The European Standard EN 71 for safety of toys consists of the following parts: Part 1: Mechanical

24、 and physical properties Part 2: Flammability Part 3: Migration of certain elements Part 4: Experimental sets for chemistry and related activities Part 5: Chemical toys (sets) other than experimental sets Part 6: Graphical symbols for age warning labelling Part 7: Finger paints Requirements and test

25、 methods Part 8: Swings, slides and similar activity toys for indoor and outdoor family domestic use Part 9: Organic chemical compounds Requirements Part 10: Organic chemical compounds Sample preparation and extraction Part 11: Organic chemical compounds Methods of analysis The standards EN 71-9, EN

26、 71-10 and EN 71-11 were mandated by the European Commission (M/229) to address the risks presented by organic compounds in toys by taking into account the potential exposure and toxicological effects of those substances considered to present the greatest risk to health. This European Standard speci

27、fies the procedures for preparing and extracting samples of toy materials prior to analysis by the methods described in EN 71-11. This part should be read in conjunction with EN 71-9, which contains requirements for certain organic compounds in toys, and EN 71-11, which specifies methods of analysis

28、. This European Standard takes into account the opinion of the Toxicology Section of the Scientific Advisory Committee published in 1992 (EUR 13976), which recommended that certain groups of chemical compounds used in toys and toy materials need to be given special attention. In drafting this Europe

29、an Standard CEN/TC 52 has considered organic chemicals that can be classified within the following groups: Solvents Preservatives Plasticisers (excluding phthalate plasticisers)1 Flame retardants Monomers Biocides (wood preservatives) Processing aids Colouring agents During the development of this E

30、uropean Standard, CEN/TC 52 has considered the requirements set out in Council Directive 82/711/EEC as amended and its supporting standards. 1Phthalate plasticisers were specifically excluded from the scope of mandate M/229. EN 71-10:2005 (E) 5 1 Scope This Part 10 of the European Standard EN 71 for

31、 safety of toys specifies sample preparation and extraction procedures for establishing the release or content of organic compounds from those toys for which requirements exist in EN 71-9. 2 Normative references The following referenced documents are indispensable for the application of this Europea
