16、3 Foreword This document (EN 71-4:2013) has been prepared by Technical Committee CEN/TC 52 “Safety of toys”, the secretariat of which is held by DS. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by
17、 August 2013, and conflicting national standards shall be withdrawn at the latest by August 2013. Attention 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 pat
18、ent rights. This document supersedes EN 71-4:2009. This document has been prepared under a mandate given 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,
19、 which is an integral part of this document. The significant changes from the previous edition of this standard are detailed in Annex D. This standard is part 4 of a series of standards for the safety of toys. This part 4 of the EN 71 series is intended to be read in conjunction with EN 71, part 1.

BS EN 71-4:2013EN 71-4:2013 (E) 5 Introduction This European Standard, EN 71-4, is intended to reduce the risks and health hazards to a child when exper
26、imental sets involving chemical experiments are used as intended or in a foreseeable way, bearing in mind the behaviour of children. During use of these experimental sets, the hazards should be kept to a minimum by the provision of appropriate information to make the experiments safe and controllabl
27、e. Therefore, this European Standard specifies warning phrases and instructions for use for experimental sets. As a general rule, experimental sets are designed and manufactured for particular ages of children. Their characteristics are related to the age and stage of development of the children, an
28、d their use presupposes certain aptitudes. Age requirements are therefore given. The requirements of this European Standard do not release parents or carers from their responsibility of watching over the child while he or she is carrying out experiments. On the contrary, the use of these sets requir
29、es close supervision by adults. BS EN 71-4:2013EN 71-4:2013 (E) 6 1 Scope This European Standard specifies requirements for the maximum amount and, in some cases, the maximum concentration of certain substances and mixtures used in experimental sets for chemistry and related activities. These substa
30、nces and mixtures are: those classified as dangerous by the EC-legislation applying to dangerous substances 1, 2 and dangerous mixtures 2, 3; substances and mixtures which in excessive amounts could harm the health of the children using them and which are not classified as dangerous by the above men
31、tioned legislation; and any other chemical substance(s) and mixture(s) delivered with the experimental set. This standard applies to experimental sets for chemistry and related activities including crystal growing sets, carbon dioxide generating experimental sets and supplementary sets. It also cove
32、rs sets for chemical experiments within the fields of mineralogy, biology, physics, microscopy and environmental science whenever they contain one or more chemical substances and/or mixtures which are classified as hazardous according to Regulation (EC) No. 1272/2008 2. This standard also specifies
33、requirements for marking, a contents list, instructions for use, eye protection and for the equipment intended for carrying out the experiments. This standard does not apply to toys that are covered by EN 71-13 (e.g. cosmetic kits). Requirements for certain other chemical toys are given in EN 71-5.
34、NOTE The terms “substance“ and “preparation“, as used in Directives 67/548/EEC 1 and 1999/45/EC 3, are also used in the “REACH Regulation”, Regulation (EC) No. 1907/2006 4. According to the Globally Harmonised System (GHS) of classification and labelling of chemicals, which in the European Union has
35、 been enacted by Regulation (EC) No. 1272/2008 (classification, labelling and packaging of substances and mixtures) 2, the timetable for the introduction of GHS has to be followed. The words “preparation” and “mixture” should be considered synonymous; both are a mixture or solution of substances tha
36、t do not react with each other. The old term “preparation” will be replaced by the new term “mixture” in due course. In this standard, only the term “mixture” is used. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensab
37、le for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

44、substances in aqueous solutions. The crystals may be grown on different materials (e.g. stones or gypsum) and can be coloured in different ways (e.g. with food colours): The expanding nature of the growing crystal is not subject to requirements within EN 71-1 for expanding materials as the expansion
