26、pounds Methods of analysis The European Standards EN 71-9, EN 71-10 and EN 71-11 were mandated by the European Commission (M/229) to address the risks presented by organic chemical compounds in toys by taking into account the potential exposure and toxicological effects of those substances considere
27、d to present the greatest risk to health. This European Standard specifies methods of analysis to enable assessment of compliance with the chemical requirements specified in EN 71-9 when toy and toy material extracts have been prepared according to the sampling procedures in EN 71-10. This part on m
28、ethods of analysis should be read in conjunction with EN 71-9, which contains requirements for certain organic chemical compounds in toys, and EN 71-10, which describes sample preparation and extraction procedures. This European Standard takes into account the opinion of the Toxicology Section of th
29、e 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 European Standard CEN/TC 52 has considered organic chemicals that can be classified within th
30、e following groups: Solvents Preservatives Plasticisers (excluding phthalate plasticisers)1 Flame retardants Monomers Biocides (wood preservatives) Processing aids Colouring agents 1 Phthalate plasticisers were specifically excluded from the scope of mandate M/229.

EN 71-11:2005 (E) 6 4 Environmental, health and safety precautions When preparing this European Standard, consideration was given to the minimisation of environmental impacts caused by the use of the methods of analysis. It is the users responsibil
40、ity to use safe and proper techniques in handling materials in the methods of analysis specified in this European Standard. Consult manufacturers for specific details such as material safety data sheets and other recommendations. Wear protective goggles and coats in all laboratory areas. Be careful
41、about substances, which are toxic and/or human carcinogens. A fume cupboard shall be used during preparation of organic solvent solutions. Solvents shall be disposed of in accordance with environmental requirements. 5 Methods of analysis 5.1 General All chemicals used for analysis shall be of analyt
42、ical grade (pro analysis) or, if unavailable, the best technical grade. Water shall be of grade 3 according to EN ISO 3696 or of a comparable quality, and demonstrably free from analytes of interest. The precision of volumetric glassware should be grade A. The analysis of toys and toy materials for
43、chemical compounds for which limits are given in Tables 2 A to 2 I of EN 71-9:2005 shall be performed in accordance with the sampling procedures specified in EN 71-10 and the methods of analysis described in this European Standard. Alternative methods of analysis are acceptable only if they are capa
44、ble of achieving at least the accuracy and precision of the methods described in this European Standard; an adequate sensitivity; and have been validated to show that the results are equivalent to those of these standard methods. 5.2 Flame retardants NOTE Methods are given for pentabromodiphenyl eth
45、er and octabromodiphenyl ether in order to enable compliance with Directive 2003/11/EC of the European Parliament and of the Council to be demonstrated for textile toy materials. 5.2.1 Principle Flame retardants are determined in acetonitrile extracts of toy materials by liquid chromatography with d
46、iode- array and mass spectrometry detection (LC-DAD-MS) using the external standard method of calibration.
