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/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.

Sicherheit von Spielzeug - Teil 4: Experimentierkästen für chemische und ähnliche Versuche

Dieses Dokument legt Anforderungen an die Höchstmengen und, in einigen Fällen, an die Höchstkonzen-trationen bestimmter Stoffe und Gemische fest, die in Experimentierkästen für chemische und ähnliche Ver-suche verwendet werden.
Bei diesen Stoffen und Gemischen handelt es sich um:
—   solche, die nach den für gefährliche Stoffe und gefährliche Gemische geltenden EU Rechtsvorschriften [1] als gefährlich eingestuft sind;
—   Stoffe und Gemische, die in übermäßigen Mengen die Gesundheit der Kinder, die sie verwenden, 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.
Dieses Dokument gilt für Experimentierkästen für chemische und ähnliche Versuche, einschließlich Experimentierkästen zur Kristallzucht und Experimentierkästen zur Erzeugung von Kohlenstoffdioxid sowie Ergänzungskästen. Es 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 [1] als gefährlich eingestuft sind.
Darüber hinaus legt dieses Dokument Anforderungen an die Kennzeichnung, die Inhaltsangabe, die Ge-brauchsanleitung, den Augenschutz und an die zur Durchführung der Versuche zu verwendende Ausrüstung fest.
Dieses Dokument gilt nicht für kombinierte Experimentierkästen, z. B. eine Kombination aus einem Chemie-experimentierkasten und einem Experimentierkasten zur Kristallzucht. Ferner gilt es 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 Begriffe „Stoff“ und „Zubereitung“ werden in der „REACH Verordnung“, Verordnung (EG) Nr. 1907/2006 [2], 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) [1] erlassen wurde, wird der Zeitplan für die Einführung des GHS eingehalten. Die Wörter „Zubereitung“ und „Gemisch“ werden als Synonyme betrachtet; 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 diesem Dokument wird ausschließlich der Begriff „Gemisch“ verwendet.

Sécurité des jouets - Partie 4: Coffrets d'expériences chimiques et d'activités connexes

Le présent document 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 :

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.

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 is followed. The words

“preparation” and “mixture” are 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.
2 Normative references

3 Terms and definitions
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 https://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 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 71-1:2014+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).

3.5
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
