AS NZS 8124.4 pdf download.Safety of toys Part 4: Experimental sets for chemistry and related activities (ISO 8124-10:2019, MOD)
1 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 dangerous by the Globally Harmonized System of Classification and Labelling of Chemicals (GHS)[1]; substances and mixtures which in excessive amounts could harm the health of the children using them and which are not classified as dangerous by the GHS; 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 the GHS[1]. This document also specifies requirements for marking, a contents list, instructions for use, eye protection and the equipment intended for carrying out the experiments. Requirements for certain other chemical toys are given in ISO 8124-11.
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: 一ISO Online browsing platform: available at https://www.iso.org/obp 一IEC Electropedia: available at http://www.electropedia.org/ 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 (3.1) 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
