Standards Development

Scope

This document 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.

These substances and mixtures are:

- those classified as hazardous by the EC-legislation applying to hazardous substances and hazardous mixtures;

- substances and mixtures which in excessive amounts could harm the health of the children using them and which are not classified as hazardous by the above-mentioned legislation; and

- any other chemical substance(s) and mixture(s) delivered with the experimental set.

This document 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.

This document also specifies requirements for marking, a contents list, instructions for use, eye protection and for the equipment intended for carrying out the experiments.

This document does not apply to combined sets, e.g. a combination of a chemistry set and a crystal growing set. It also 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.

Purpose

A standardization request which includes the revision/amendment of EN 71-4 is expected to be issued soon (vote in committee on standards ends in September 2022). As requested in the standardization request the project will focus on revising the requirements on packaging and closures.

Note: in case the WI is based on documents from other organizations than ISO/IEC, please specify it here
