For the purposes of this document the following terms and definitions apply.
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

ISOURCE: EN 71-4:20 13, 3.21
3.3
plaster of Paris (gypsum) moulding set
toy containing moulds into which a mixture of water and gypsum is poured and allowed to harden

3.4
oven-hardening plasticised PVC modelling clay set

3.5
polystyrene granules set
toy to be used in substitution of ceramic materials to create decorative articles or models by fusion of a
polymer by heating in an oven up to a maximum of 180 °C
5.4 Safety rules
The instructions for use shall in addition to the rules required in 9.4 contain the following safety rules:
— “Do not place the material in the mouth.w;
— ‘Do not exceed a hardening temperature of 130 °C or harmful gases may be produced.”;
— “Do not exceed a hardening time of 30 minutes.”;
— “The hardening process is not part of the function of the toy and should be carried out by the supervising adult.”;
— ‘Use a domestic oven thermometer, e.g. bimetal, to measure the temperature.”;
— “Do not use a glass thermometer.”;
— “Do not heat the material and cook food at the same time in a domestic oven
— “Do not use a microwave oven.”.
6 Moulding sets
6.1 Polystyrene granules sets
6.1,1 Chemical substances
These sets shall contain uncoloured and coloured polystyrene granules in accordance with Table 3.
6.1.4 Safety rules
The instructions for use shall in addition to the rules required in 9.4 contain the following safety rules:
— ‘Do not exceed a melting temperature of 180 °C.’;
— ‘The melting process is not part of the function of the toy and should be carried out by the supervising adult.”;
— ‘Use a domestic oven thermometer, e.g. bimetal, to measure the temperature.’;
— ‘Do not swallow material.”;
— ‘Do not heat the material and cook food at the same time in a domestic oven.”;
— ‘Do not use a glass thermometer.”;
— ‘Do not exceed the maximum recommended processing period.’;
— ‘Do not use a microwave oven.”.
6.2 Embedding sets
6.2.1 General
Only preservatives permitted in foodstuffs (see [7]) and/or cosmetics, except those preservatives which are only allowed in cosmetic products that are rinsed-off after use, (see [8]) shall be used.
Other substances classified as dangerous substances (see [5]) shall not be used in embedding sets. NOTE Substances such as gelatine or agar could be utilized with suitable preservation.
6.2.2 Packaging
The name(s) of any preservative(s) used shall be indicated on the primary packaging.
8.1 General
Markings shall be visible, easily legible, indelible and in the national language(s) of the country of sale.
If the container is too small to carry all the information necessary an additional instruction leaflet shall be supplied with the package.
8.2 Marking of the primary packaging
8.2.1 General
The primary packaging shall indicate any dangerous substances or dangerous mixtures (see [5j) that are recommended but not included in the toy.
NOTE Examples for dangerous substances or dangerous mixtures that are recommended but not included in the toy are adhesives, paints or lacquers.
8.2.2 Manufacturer’s identification
The primary packaging shall bear the name, registered trade name or registered trade mark of the manufacturer or the importer and the address at which they can be contacted.
NOTE If the manufacturer (declaring himself as a manufacturer by putting his name and address on the toy) Is outside the Community and the products are placed on the EU market by an Importer, the toy will bear two addresses: the one of the manufacturer and the one of the importer.
Chemical toy (sets) shall bear a type, batch, serial or model number or other element allowing their identification.
8.2.3 Warning phrases

All chemicals used for analysis shall be of analytical grade (pro analysis) or, if unavailable, the best technical grade. Water shall be of grade 3 according to EN ISO 3696 or of a comparable quality, and demonstrably free from analytes of interest.
The precision of volumetric glassware should be grade A.
The analysis of chemical toys and chemical toy materials for chemical compounds shall be performed in accordance with the methods of analysis described in this European Standard. Alternative methods of analysis or modifications to the procedures described are acceptable only if they are capable of achieving at least the accuracy and precision of the methods described in this European Standard, an adequate sensitivity and have been validated to show that the results are equivalent to those of these standard methods.
10.2 Determination of plasticisers in oven-hardening polyvinyl chloride (PVC) modelling clay sets
10.2.1 Principle
The plasticiser content is determined by solvent extraction to quantitatively extract the plasticiser from a known weight of PVC material using a Soxhlet extractor. Hexane is used to extract citric acid esters and alkylsulfonic acid esters. Methanol is used to extract adipic acid polyesters. Indicative plasticiser content can be determined by evaporating off the solvent and weighing the solvent residue and identifying the plasticiser by Attenuated Total Reflectance-Fourier Transform-Infra Red (ATR-FT-IR) Spectrometry.
Determination of plasticiser(s) content Is by Gas Chromatography-Mass Spectrometry (GC-MS) for alkylsulfonic acid phenyl ester and citric acid esters. Adipic acid esters are quantified gravimetrically.
This method is also partly used for the determination of plasticisers in solvent-based adhesives and solvent-based paints or lacquers (see 10.6.4).
