Annex C (informative): Environmental considerations
Annex D (informative): Significant technical changes between this European Standard and the previous version
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of an identical text or by endorsement, at the latest by August 2013, and conflicting national standards shall be withdrawn at the latest by August 2013.
This document supersedes EN 71-4:2009.
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.

CEN/TR 15071:2005, Safety of toys — National translations of warnings and instructions for use in EN 71
CEN/TR 15371:2013, Safety of toys — Replies to requests for interpretation of EN 71-1, EN 71-2, and EN 71-8.
According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
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.
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.
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.

3.1 chemical toy
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 dioxideliberating 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
4 Chemical substances in experimental sets1

5.2.6.3 Procedure
Weigh the pycnometer (m0). Make sure that the fraction from the glass sample is clean. Place it in the pycnometer and re-weigh the pycnometer (m2). Then fill up the pycnometer with water and place it in a water bath until the contents equilibrate at 20 °C. Top up the pycnometer with water. Remove the pycnometer from the water bath, dry exterior and weigh (m3). Empty the pycnometer. Fill up the pycnometer with water and place in water bath until the contents equilibrate at 20 °C. Top up the pycnometer with water, dry and weigh. Record the weight (m1).
ρ Glass = ( m 2 − m 0 ) ( m 1 − m 3 + m 2 − m 0 ) · ρ Water ( 20 ° c )
ρGlass is the density of the glass sample in g/cm3;
ρWater ( 20 °C ) is the density of water at 20 °C ( ρWater ( 20 °C ) = 0,9882 g / cm3 );
m0 is the mass of the empty pycnometer, in g;
m1 is the mass of the pycnometer filled with water, in g;
m2 is the mass of the pycnometer with the glass sample, in g;
m3 is the mass of the pycnometer with glass sample and water, in g.
NOTE Reference densities for certain types of glass are:
(2,40 ± 0,05) g/cm³ for sheet window glass;
(2,48 ± 0,05) g/cm³ for soft soda glass;
(2,25 ± 0,05) g/cm³ for borosilicate glass;

The following safety rules shall be given for carbon dioxide generating experimental sets:
Do not eat or drink in the experimental area. 26
If the carbon dioxide generating experimental set contains containers that comply with 5.2.4.1 the following safety rule shall also be given:
Test methods for closures of reagent containers
A.1 Closure test A
Open the closure and re-close it ten times. Apply an upward vertical force of (70 ± 2) N on the cap. Examine whether the cap is still closed.
Apply a downward vertical force of (30 ± 2) N on the cap. Apply a maximum torque of (0,5 ± 0,05) Nm in a clockwise and then anticlockwise direction. Examine whether the cap is still closed.
A.2 Closure test B
Open the closure by using the external tool and re-close it ten times. Remove the external tool. The stopper shall be in the locked position. Apply a downward vertical force of (30 ± 2) N on the cap. Rotate the cap in a clockwise and then anticlockwise direction with a maximum of (0,5 ± 0,05) Nm for a maximum of a full turn each way. Examine whether the cap is still closed.
Apply an upward vertical force of (70 ± 2) N on the cap. Examine whether the cap is still closed. Attach the external tool and apply a force of 10 N on the tool in the most onerous direction. Examine whether the cap is still closed.
A.3 Closure test C
Fill the container with water. The filling volume shall be ¾ of the container volume. Attach the closure. Drop the filled container including its closure with its closure facing downwards five times from a height of (850 ± 50) mm on to a 4 mm thick steel plate, which has a 2 mm thick coating of Shore A hardness (75 ± 5) as measured according to EN ISO 868 or ISO 7619-1, and which is placed on a non-flexible horizontal surface.
Check visually for any breaks, cracks or leakages of the closure.
B.1 Classification of substances and mixtures
Substances and mixtures in the various tables of the standard are classified according to Regulation (EC) No. 1272/2008 [2].
For those substances which have been classified and labelled according to chemical supplier’s selfclassification (which is based on Regulation (EC) No. 1272/2008 [2]), the standard generally specifies a precautionary classification corresponding to self-classification being used by one or more chemical suppliers/manufacturers.
The precautionary classifications and labelling requirements in this standard were considered reasonable for educational purposes and to ensure harmonised labelling and safety requirements.
The criterion for the hazard classification of colourants and colouring materials in experimental sets is more stringent than the classification of several of the allowed chemical substances. This was considered necessary because colourants and colouring materials are not specified in this standard and because there is a good range of appropriate colourants (e.g. food colours or colouring tablets) available on the market.
B.2 Crystal growing sets
Because of their similarity to chemistry sets, crystal growing sets have been specifically included within the scope of this standard in order to specify safety requirements that have been applicable to chemistry sets for many years. These safety requirements have been adapted to acknowledge the larger quantities of a small number of chemicals that are required to grow crystals and to address the long lasting period while the crystals are growing. The standard requires that specific safety information be provided to supervising adults to make them aware of the risks associated with unattended, super-saturated crystal growing solutions.
B.3 Carbon dioxide generating experimental sets
The inclusion of carbon dioxide generating experimental sets takes into account the particular interest in volcanoes or similar natural phenomenon. Even if these sets deal with mineralogical, geological and geographic aspects, the only chemical experiment is to generate carbon dioxide. In contrast, experimental sets for chemical experiments within the fields of mineralogy (chemistry sets) contain chemical substances in order to do different chemical reactions (e.g. to identify different types of minerals, stones or gemstones). The generation of carbon dioxide allows many dynamic play possibilities and the specification of safety requirements limits the hazards that may result from these experiments. As the focus of this standard is on setting safety requirements for toys that involve carrying out chemical experiments, other carbon dioxide using toys like racing cars etc. are excluded from the scope.
The focus is on experiments showing the characteristics of the included substances and their reaction product (carbon dioxide).
Every product affects the environment in the course of its life cycle from raw material acquisition through production, distribution and use, to disposal. The environmental impacts are consequences of the consumption of energy and resources and the generation of waste as well as the emission of substances into air, water and soil. The magnitude of the environmental impacts during the various life cycle changes depends on a number of choices made in the design of the product. These relate to aspects such as choice of materials, production methods, and the possibility of maintenance and recycling. Manufacturers and distributors should consider the environmental impact of their product, for example by:
minimising the use of environmentally harmful substances;
selecting the best available technology and techniques to reduce consumption of energy and materials;
considering the use of recycled materials for product and packaging;
encouraging responsible end of life disposal by the user including guidance on separation and identification of any recyclable components and packaging;
using materials, components, and manufacturing facilities, which have declared documented environmental policies.
General The standard has been revised to reflect new particular safety requirements in Directive 2009/48/EC, in comparison to 88/378/EEC, and the labelling requirements for chemical substances of Regulation (EC) No 1272/2008, as it would apply to single supplied substances.
1 The scope has been extended to cover crystal growing sets and carbon dioxide generating experimental sets.
3 Terms and definitions of “chemical toy”, “experimental set”, “crystal growing set” and “carbon dioxide generating experimental set” and cosmetic kit have been added and the definition of chemistry set has been adjusted.
4.1 Clove oil has been removed in Table 1. In Table 1, Table 2 and Table 3 the danger symbols have been replaced by the corresponding GHS pictograms and the signal words and index numbers have been added. Colorants and colouring materials may under certain conditions be included in a chemistry set in addition to the substances specified in Tables 1 and 2.
4.2 Requirements for crystal growing sets including an allowed substance list (Table 4) have been added.
4.3 Requirements for carbon dioxide generating experimental sets including an allowed substance list (Table 5) have been added.
5.2.4 Requirements for the packaging of crystal-growing substances and carbon dioxide generating substances have been added.
5.5 The test method for eye protection has been removed. Eye protection shall be provided for experimental sets containing substances which have to be marked with the GHS pictogram GHS05 and for chemistry sets. A reference to Directive 89/686/EEC has been added.
6 The marking requirements have been adjusted to Directive 2009/48/EC and Regulation (EC) No 1272/2008.
7 The requirements for the content list have been revised (e.g. Risk/Safety-phrases have been replaced by the H-and-P-phrases). The general first aid information has been slightly adjusted.
8.3 The safety rules for chemistry sets have been revised and safety rules for crystal growing sets and carbon dioxide generating experimental sets have been added.
NOTE The technical changes referred include the significant technical changes from the revised European Standard but is not an exhaustive list of all modifications from the previous version.
This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association to provide a means of conforming to Essential Requirements of the New Approach Directive 2009/48/EC of the European Parliament and of the Council of 18 June 2009 on the safety of toys.
