BS 71-4:2020 pdf download – Safety of toys Part 4: Experimental sets for chemistry and related activities This document specifies requirements for the maximum amount, and in some cases, the maximumconcentration of certain substances and mixtures used in experimental sets for chemistry and relatedactivities. These substances and mixtures are: – those classified as hazardous by the EC-legislation applying to hazardous substances and hazardous mixtures [1]; substances and mixtures which in excessive amounts could harm the health of the children usingthem 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 crystalgrowing sets, carbon dioxide generating experimental sets and supplementary sets. It also covers sets forchemical experiments within the fields of mineralogy, biology, physics, microscopy and environmentalscience whenever they contain one or more chemical substances and/or mixtures which are classifiedas hazardous according to Regulation (EC) No.1272/2008 [1]. This document also specifies requirements for marking,a contents list, instructions for use, eyeprotection 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 crystalgrowing set. It also does not apply to toys that are covered by EN71-13 (e.g. cosmetic kits).Requirements for certain other chemical toys are given in EN 71-5. NOTE The terms “substance” and “preparation” , are used in the “REACH Regulation”，Regulation (EC) No.1907/2006 [2].According to the Globally Harmonized System (GHS) of classification and labelling of chemicals,which in the European Union has been enacted by Regulation (EC) No.1272/2008 (classification, labelling andpackaging of substances and mixtures) [1], the timetable for the introduction of GHS is followed. The words”preparation” and “mixture” are considered synonymous; both are a mixture or solution of substances that do notreact with each other.The old term “preparation” will be replaced by the new term “mixture” in due course. In thisdocument, only the term”mixture” is used. 2Normative references The following documents are referred to in the text in such a way that some or all of their contentconstitutes requirements of this document.
