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 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 [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.
Sicherheit von Spielzeug - Teil 4: Experimentierkästen für chemische und ähnliche Versuche
Diese Europäische Norm legt Anforderungen an die Höchstmengen und, in einigen Fällen, an die Höchstkonzentrationen bestimmter Stoffe und Gemische fest, die in Experimentierkästen für chemische und ähnliche Versuche verwendet werden.
Bei diesen Stoffen und Gemischen handelt es sich um:
solche, die nach den für gefährliche Stoffe [1], [2] und gefährliche Gemische [2], [3] geltenden EU Rechtsvorschriften als gefährlich eingestuft wurden;
Stoffe und Gemische, die in übermäßigen Mengen die Gesundheit der Kinder schädigen könnten und die nicht durch die vorstehend genannten Rechtsvorschriften als gefährlich eingestuft sind; und
sonstige chemische Stoffe und Gemische, die in einem Experimentierkasten enthalten sind.
Diese Norm gilt für Experimentierkästen für chemische und ähnliche Versuche, einschließlich Experimentierkästen zur Kristallzucht und Experimentierkästen zur Erzeugung von Kohlenstoffdioxid sowie Ergänzungskästen. Sie umfasst außerdem Experimentierkästen mit chemischen Versuchen auf dem Gebiet der Mineralogie, Biologie, Physik, Mikroskopie und der Umweltwissenschaften, sofern diese einen oder mehrere chemische Stoffe und/oder Gemische enthalten, die nach der Verordnung (EG) Nr. 1272/2008 [2] als gefährlich eingestuft sind.
Außerdem legt diese Norm Anforderungen an die Kennzeichnung, die Inhaltsangabe, die Gebrauchsanleitung, den Augenschutz und an die zur Durchführung der Versuche zu verwendende Ausrüstung fest.
Diese Norm gilt nicht für Spielzeug, das in EN 71-13 behandelt wird (z.B. Kosmetik-Sets). Anforderungen an bestimmte andere chemische Spielzeuge sind in EN 71-5 enthalten.
ANMERKUNG Die Fachausdrücke „Stoff“ und „Zubereitung“, wie in den Richtlinien 67/548/EWG [1] und 1999/45/EG [3] verwendet, werden ebenfalls in der „REACH-Verordnung“, Verordnung (EG) Nr. 1907/2006 [4], verwendet. Nach dem Global Harmonisierten System (GHS) zur Einstufung und Kennzeichnung von Chemikalien, das in der Europäischen Union durch die Verordnung (EG) Nr. 1272/2008 (Einstufung, Kennzeichnung und Verpackung von Stoffen und Gemischen) [2] erlassen wurde, muss der Zeitplan für die Einführung des GHS eingehalten werden.
Die Wörter „Zubereitung“ und „Gemisch“ sollten als Synonyme betrachtet werden; beides sind Gemische oder Lösungen aus Stoffen, die nicht miteinander reagieren. Der veraltete Begriff „Zubereitung“ wird zu gegebener Zeit durch den neuen Begriff „Gemisch“ ersetzt. In dieser Norm wird ausschließlich der Begriff „Gemisch“ verwendet.
Sécurité des jouets - Partie 4 : Coffrets d'expériences chimiques et d'activités connexes
La présente Norme Européenne spécifie les exigences relatives à la quantité maximale et, dans certains cas, à la concentration maximale de certaines substances et de certains mélanges utilisés dans les coffrets d’expériences chimiques et d’activités connexes.
Ces substances et mélanges sont les suivants :
- ceux classés comme dangereux par la législation de l’UE s’appliquant aux substances dangereuses [1], [2] et aux mélanges dangereux [2], [3] ;
- des substances et mélanges qui, en quantités excessives, pourraient être néfastes pour la santé des enfants les utilisant, mais qui ne sont pas classés comme dangereux par la législation susmentionnée ; et
- toute autre substance et tout autre mélange fournis avec le coffret d’expériences.
La présente Norme s’applique aux coffrets d’expériences chimiques et d’activités connexes, y compris les coffrets de développement de cristaux, les coffrets d’expériences produisant du dioxyde de carbone et les coffrets additionnels. Elle couvre également les coffrets permettant de faire des expériences chimiques dans les domaines de la minéralogie, de la biologie, de la physique, de la microscopie et des sciences de l’environnement, lorsqu’ils contiennent une ou plusieurs substances et/ou un ou plusieurs mélanges chimiques qui sont classés comme dangereux selon le Règlement (CE) N° 1272/2008/CE [2].
La présente norme spécifie également des exigences relatives au marquage, à la liste des informations, à la notice d’utilisation, à l’équipement de protection des yeux et au matériel destiné à être utilisé pour réaliser les expériences.
Les exigences relatives aux autres jouets chimiques sont données dans l’EN 71-5.
NOTE Les termes « substance » et « préparation » utilisés dans les Directives 67/548/CEE [1] et 1999/45/CE [3] sont également employés dans la réglementation « REACH », Règlement (CE) N° 1907/2006 [4]. Selon le Système général harmonisé de classification et d’étiquetage des produits chimiques (SGH), qui a été adopté au sein de l’Union européenne via le Règlement (CE) N° 1272/2008 (classification, étiquetage et emballage des substances et des mélanges) [2], le calendrier pour l’introduction du SGH doit être suivi.
Il convient de considérer les termes « préparation » et « mélange » comme des synonymes ; les deux concernent des mélanges ou des solutions de substances qui ne réagissent pas les unes avec les autres. L’ancienne dénomination « préparation » sera remplacée par le nouveau terme « mélange » en temps opportun. Dans la présente norme, seul le terme « mélange » est employé.

Introduction
This European Standard, EN 71-4, 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 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, and 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
requires close supervision by adults.

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 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 [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.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
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 adult
3.2
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
3.3
chemistry set
experimental set consisting of one or more chemical substances and/or mixtures with or without equipment
intended 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 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.
3.4
crystal growing set
experimental set consisting of one or more chemical substances for growing crystals without any reaction
between the supplied substances
Note 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 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).
3.5
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 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.
3.6
supplementary set
incomplete experimental set which is intended to be used with a complete experimental set
3.7
cosmetic kit
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

Introduction
This European Standard EN 71-4 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. Warning phrases and instructions for
use are required for experimental sets according to this European Standard.
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. Therefore age requirements are 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
requires close supervision by adults.

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 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.
Requirements for 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.

The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
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 adult
3.2
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
3.3
chemistry set
experimental set consisting of one or more chemical substances and/or mixtures with or without equipment
intended for carrying out chemical experiments
NOTE 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 1272/2008/EC,excluding crystal growing sets and
carbon dioxide generating experimental sets.
3.4
crystal growing set
experimental set consisting of one or more chemical substances for growing crystals without any reaction
between the supplied substances
NOTE A carbon dioxide generating experimental 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 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).
3.5
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 in
an open system without any gas-tight restriction or confinement
NOTE 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.
3.6
supplementary set
incomplete experimental set which is intended to be used with a complete experimental set
4 Chemical substances in experimental sets
4.1 Chemistry sets
Only the chemical substances, mixtures and indicators given in Table 1 and Table 2 may be supplied in
chemistry sets or in a supplementary set for a chemistry set up to the amounts and concentrations specified in
those tables.
NOTE 1 The quality of the chemicals used should be appropriate for the experiments described. In particular the
chemicals should not contain impurities or substances which allow undefined and dangerous reactions to occur.
