FprEN 71-4
(Main)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 substances 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 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. It also covers 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/EC [2].
This standard also specifies 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.
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 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 that 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.

Introduction
This document is intended to reduce the risks and health hazards to a child when experimental 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 controllable. Therefore, this document
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, and their use
presupposes certain aptitudes. Age requirements are therefore given.The requirements of this document 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 requires close supervision by adults.---------------------- Page: 7 ----------------------

1 Scope
This document 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 substances and mixtures are:
— those classified as hazardous by the EC-legislation applying to hazardous substances and hazardous
mixtures [1];— substances and mixtures which in excessive amounts could harm the health of the children using
them and which are not classified as hazardous by the above mentioned legislation; and
— any other chemical substance(s) and mixture(s) delivered with the experimental set.
This document applies to experimental sets for chemistry and related activities including crystal
growing sets, carbon dioxide generating experimental sets and supplementary sets. It also covers 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 [1].This document also specifies requirements for marking, a contents list, instructions for use, eye
protection and for the equipment intended for carrying out the experiments.This document does not apply to combined sets, e.g. a combination of a chemistry set and a crystal
growing set. It also 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.NOTE The terms “substance” and “preparation”, are used in the “REACH Regulation”, Regulation (EC) No.
1907/2006 [2]. According to the Globally Harmonized System (GHS) of classification and labelling of chemicals,
which in the European Union has been enacted by Regulation (EC) No. 1272/2008 (classification, labelling and
packaging of substances and mixtures) [1], 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 that do not react with each other. The old term “preparation” will be replaced by
the new term “mixture” in due course. In this document, only the term “mixture” is used.

For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
• IEC Electropedia: available at http://www.electropedia.org/• ISO Online browsing platform: available at http://www.iso.org/obp
3.1
chemical toy
toy intended for the direct handling of chemical substances and mixtures and which is used in a manner
appropriate to a given age-group and under the supervision of an adult3.2
experimental set
chemical toy where the experimental and explorative character in playing with single chemical
substances and mixtures along strict instructions dominates over the creative ideas of the user
3.3chemistry set
experimental set consisting of one or more chemical substances and/or mixtures with or without
equipment intended for carrying out chemical experimentsNote 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 and/or mixtures which are classified as hazardous according to Regulation (EC) No.
1272/2008, excluding crystal growing sets and carbon dioxide generating experimental sets.
3.4crystal growing set
experimental set consisting of one or more chemical substances for growing crystals without any
reaction between the supplied substancesNote 1 to entry: A crystal growing set is used to grow crystals of different 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 71-1:2014+A1:2018 for expanding materials as the expansion is not related to the absorption of water in the
crystal and the expansion usually takes place over a long period of time (several days or weeks).
3.5carbon 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 in an 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
generate carbon dioxide in order to demonstrate speed, velocity or noise.---------------------- Page: 9 ----------------------
