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:
— ISO Online browsing platform: available at
— IEC Electropedia: available at
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
(SOURCE: ISO 8124-2:2014, 3.1)
3.2 experimental set
chemical toy (11) in which the experimental and explorative character in playing with single chemical substances and mixtures is guided by strict instructions that dominate over the creative ideas of the user
3.3 chemistry set
experimental set (3.2) 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 the GHS, excluding crystal- growing sets and carbon-dioxide-generating experimental sets.
3.4 crystal-growing set
experimental set (3.2) 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 can 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
ISO 8124-1 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 (3.2) 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 (3.2) which is intended to be used with a complete experimental set
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 or dangerous reactions to occur.
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 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.
The instructions for use may suggest the use of other substances that are not classified as dangerous substancesill (e.g. sucrose or table sugar) or mixtures that are not classified as dangerous mixturesiJi. Other dangerous substances shall not be supplied with the set.
The substances and mixtures in a chemistry set or in a supplementary set of a chemistry set shall be supplied in containers which are provided with closures (see 8124-10 pdf download.
