31、13 (E) 6 Introduction There are ongoing developments in the following area: the influence of the mouthing behaviour (mouthing time and sucking/chewing) on the migration out of teethers and other elastomers than balloons. WARNING N-nitrosamines can endanger human health owing to their toxicity. Perso
32、ns using this European Standard should be familiar with normal laboratory practice. This European Standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure
33、compliance with any national regulatory conditions.

34、he requirements and test methods for N-nitrosamines and N-nitrosatable substances for: toys and parts of toys made from elastomers and intended for use by children under 36 months; toys and parts of toys made from elastomers and intended to be placed in the mouth; finger paints for children under 36
35、 months. EXAMPLES Examples of toys made from elastomers are balloons and teethers. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
