The objective of this Standard is to specify requirements for the maximum amount of certain substances and preparations used in experimental sets for chemistry and related activities. The standard applies to chemistry sets and supplementary sets. It also covers toys for experiments within the fields of mineralogy, biology, physics, microscopics and environmental sciences whenever they contain one or more chemical substances and/or preparations. It also specifies requirements for marking, contents list, instructions for use and for equipment intended for carrying out the experiments.
