BS EN 71-4:2020 pdf free.Safety of toys Part 4: Experimental sets for chemistry and related activities.
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.
The quality of the chemicals used should be appropriate for the experiments described. In particular, the chemicals should not contain impurities or substances that allow undefined and dangerous reactions to occur.
Furthermore, colorants and colouring materials which are not specified in Table 2 may be supplied in chemistry sets if they do not react with the substances and mixtures of the set and if they do not fulfil the criteria of any of the following hazard classes:
— “acute toxicity” (hazard class 3.1),
— skin corrosion/irritation” (hazard class 3.2),
— “serious eye damage/eye irritation” (hazard class 3.3),
— “respiratory or skin sensitisation” (hazard class 3.4),
— “germ cell mutagenicity’ (hazard class 3.5),
— “carcinogenicity” (hazard class 3.6),
— “reproductive toxicity” (hazard class 3.7),
— “specific target organ toxicity — single exposure” (hazard class 3.8),
— “specific target organ toxicity — repeated exposure” (hazard class 3.9),
— “aspiration hazard” (hazard class 3.10).
Colorants which are permitted for use in food or cosmetics may be provided.
NOTE 1 The classification is detailed in Regulation (EC) No. 1272/ 2008 (Annex I, Part 3: Health Hazards).
Besides the chemical substances, mixtures and indicators given in Table 1 and Table 2 and colorants and colouring materials, only food additives and their mixtures (see Regulation (EC) 1333/2008 [5]) may be supplied in chemistry sets, if pure food additives are not classified as hazardous substances [1] or mixtures are not classified as hazardous mixtures [1].
NOTE 2 Samples of rocks, stones, minerals on which to perform experiments in order to distinguish their composition are sometimes supplied with the set.
4.1.2 Inclusion for experiments (as mentioned in the instructions but not supplied in the chemistry set)
The use of reagents listed in Table 3 may be suggested in the instructions at concentrations not exceeding those specified in this table. The substances specified in Table 3 shall not be supplied in a chemistry set.
Apart from its presence in tincture of iodine, denatured alcohol (ethanol) shall not be supplied in a chemistry set. However, where experiments contained in the instructions of a chemistry set require it, the use of denatured alcohol may be suggested in the instructions.
The instructions for use may suggest the use of other substances that are not classified as hazardous substances [1J or mixtures that are not classified as hazardous mixtures [1] (e.g. sucrose, table sugar. starch or flour).
4.1.3 Requirements for packaging in containers
The substances and mixtures in Table 1 and 2 in a chemistry set or in a supplementary set of a chemistry set shall be supplied in containers (see 5.2.3) which are provided with closures (see 5.2.4.1).
These pictograms are taken from Regulation (EC) No. 1272/2 008 of the European Parliament and the Council of 16 December 2008 (also named GHS or CLP) on the classification, labelling and packaging of substances and mixtures. The use of these pictograms should comply with the requirements of Annex I to this regulation 111.

4.2 Crystal growing sets
The chemical substances given in Table 4 may be supplied in ciystal gro wing sets or in a supplementary set for a crystal growing set up to the amounts specified in that table.
A crystal growing set shall only contain substances which cannot react between each other.
The quality of the chemicals used in crystal growing sets 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.
Besides the chemical substances given in Table 4 only colourants and colouring materials which do not fulfil the criteria of any of the following hazard classes:
— “acute toxicity” (hazard class 3.1),
— “skin corrosion/irritation” (hazard class 3.2),
— “serious eye damage/eye irritation” (hazard class 3.3),
— “respiratory or skin sensitisation” (hazard class 3.4),
— “germ cell mutagenicity” (hazard class 3.5),
— “carcinogenicity” (hazard class 3.6),
— “reproductive toxicity” (hazard class 3.7),
— “specific target organ toxicity — single exposure” (hazard class 3.8),
— “specific target organ toxicity — repeated exposure” (hazard class 3.9),
— “aspiration hazard” (hazard class 3.10),
shall be supplied in ciystal growing sets. Colourants which are permitted for use in food or cosmetics may be provided.
NOTE The classification is detailed in Regulation (EC) No. 1272/2008 (Annex I, Part 3: Health Hazards).
If substances are supplied as mixtures or if substances/mixtures are supplied in solution, their solid contents shall not exceed the amounts specified in Table 4.
Samples of materials on which to grow the crystals may be supplied with the set (e.g. plaster of Paris (gypsum), different stones, different minerals) without limits to their quantities. For gypsum, applicable requirements are specified in EN 71-5:2015 (i.e. labelling, etc.).
The substances and mixtures in Table 4 in a crystal growing set or in a supplementaiy set for a crystal growing set shall be supplied in child-resistant packaging (see 5.2.4.2).
4.3 Carbon dioxide generating experimental sets
The chemical substances given in Table 5 may be supplied in carbon dioxide generating experimental sees whose function relies on the generation of carbon dioxide. The amounts supplied in a single set shall not exceed those specified in Table 5. If mixtures of these substances are supplied in solid form, the single mixture shall consist of stoichiometric equivalent amounts of acidic and C02-generating substances.
The quality of the chemicals used in carbon dioxide generating experimental sets 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.
Besides the chemical substances given in Table 5 carbon dioxide generating experimental sets may only contain gypsum or colourants. For gypsum, applicable requirements are specified in EN 71-5:2015 (i.e. labelling, etc.). Only colourants and colouring materials which do not fulfil the criteria of any of the following hazard classes:
— “acute toxicity” (hazard class 3.1),
— “skin corrosion/irritation” (hazard class 3.2),
— “serious eye damage/eye irritation” (hazard class 3.3),
— “respiratory or skin sensitisation” (hazard class 3.4),
— “germ cell mutagenicity” (hazard class 3.5),
— carcinogenicity” (hazard class 3.6),
— “reproductive toxicity” (hazard class 3.7),
— “specific target organ toxicity — single exposure” (hazard class 3.8),
— “specific target organ toxicity — repeated exposure” (hazard class 3.9).
— “aspiration hazard” (hazard class 3.10),
shall be supplied in carbon dioxide generating experimental sets. Colourants that are permitted for use in food or cosmetics may be provided.
NOTE The classification is detailed in Regulation (EC) No. 1272/2008 (Annex I, Part 3: Health Hazards).
If substances are supplied as mixtures or if substances/mixtures are supplied in solution, their solid contents shall not exceed the amounts specified in Table 5.
The substances in Table S in a carbon dioxide generating experimental set shall be supplied in child- resistant packaging (see 5.2.4.3).BS EN 71-4 pdf free download.BS EN 71-4:2020 Safety of toys Part 4: Experimental sets for chemistry and related activities
