BS EN 71-4:2013 pdf download – Safety of toys Part 4: Experimental sets for chemistry and related activities
This European Standard specifies requirements for the maximum amount and, in some cases, the maximumconcentration of certain substances and mixtures used in experimental sets for chemistry and relatedactivities.
These substances and mixtures are:
those classified as dangerous by the EC-legislation applying to dangerous substances ，anddangerous mixtures .
substances and mixtures which in excessive amounts could harm the health of the children using themand which are not classified as dangerous by the above mentioned 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. lt also covers sets for chemicalexperiments within the fields of mineralgy， biology，physics, microscopy and environmental sciencewhenever they contain one or more chemical substances andlor mixtures which are classified as hazardousaccording to Regulation(EC) No.1272/2008.
This standard also specifies requirements for marking, a contents list,instructions for use, eye protection andfor the equipment intended for carrying out the experiments.
This standard does not apply to toys that are covered by EN71-13(e.g. cosmetic kits).Requirements forcertain other chemical toys are given in EN 71-5.
NOTE The terms “substance” and”preparation”, as used in Directives 67/548/EEC  and 199945/EC , are alsoused in the “REACH Regulation’，Regulation (EC) No. 1907/2006 . According to the Globally Harmonised System(GHS) of classification and labelling of chemicals,which in the European Union has been enacted by Regulation (EC) No.1272/2008 (classication,labelling and packaging of substances and mixtures) , the timetable for the introduction ofGHS has to be followed.
The words “preparation” and “mixture”should be considered synonymous; both are a mixture or solution of substancesthat do not react with each other. The old term “preparation” will be replaced by the new term “mixture” in due course. Inthis standard, only the term “mixture”” is used.

3Terms and definitions
For the purposes of this document,the following terms and definitions apply.
toy intended for the direct handling of chemical substances and mixtures and which is used in a mannerappropriate to a given age-group and under the supervision of an adult
chemical toy where the experimental and explorative character in playing with single chemical substances andmixtures along strict instructions dominates over the creative ideas of the user
experimental set consisting of one or more chemical substances and/or mixtures with or without equipmentintended for carrying out chemical experiments
Note 1 to entry: The definition also covers experimental sets for chemical experiments within the fields of mineralogy,biology, physics, microscopy and environmental sciences whenever they contain one or more chemical substances andiormixtures which are classifed as hazardous according to Regulation (EC)No 1272/2008,excluding crystal growing setsand carbon dioxide generating experimental sets.
crystal growing set
experimental set consisting of one or more chemical substances for growing crystals without any reactionbetween the supplied substances
Note 1 to entry: A crystal growing set is used to grow crystals of different substances in aqueous solutions. Thecrystals may be grown on different materials (e.g. stones or gypsum) and can be coloured in different ways (e.g. with foodcolours): The expanding nature of the growing crystal is not subject to requirements within EN 71-1 for expandingmaterials as the expansion is not related to the absorption of water in the crystal and the expansion usually takes placeover a long period of time (several days or weeks).
carbon dioxide generating experimental set
experimental set consisting mainly of a carbon dioxide-donor substance or mixture and a carbon dioxide-liberating substance or mixture which after combination generate carbon dioxide in the presence of water inan open system without any gas-tight restriction or confinement
Note 1 to entry. The set is used to carry out and observe chemical reactions where there is no intention to generatecarbon dioxide in order to demonstrate speed, velocity or noise.
incomplete experimental set which is intended to be used with a complete experimental set
toy, the purpose of which is to assist a child to learn to make products such as fragrances, soaps, creams,shampoos, bath foams, glosses, lipsticks, other make-up, tooth-paste and conditioners
