BS EN 71-4-2009 pdf download.Safety of toys Part 4 : Experimental sets for chemistry and related activities.
3.1
chemistry set
toy consisting of one or more chemical substances and/or preparations with or without equipment intended for carrying out chemical experiments
NOTE The definition also covers toys for expenments within the fields of mineralogy, biology, physics, microscopics and environmental sciences whenever they contain one or more chemical substances and/or preparations.
3.2
supplementary set
chemistry set wtiich Is intended to be used with a complete chemistry set
4 Chemical substances
Only chemical substances, preparations and indicators given In Table 1 and Table 2 may be supplied in chemistry sets up to the amounts stated.
NOTE The quality of the chemicals used should be appropriate for the experiments described: in particular the chemicals should not contain impurities or substances which allow undefined and dangerous reactions.
Where experiments contained in the instructions of a set require it, denatured methylated spirits may be prescribed in the instructions. Also the reagents listed in Table 3 may be prescribed in the instructions at concentrations not exceeding those specified in this table. The substances specified in Table 3 shall not be provided with the chemistry set. The instructions for use may prescribe the use of other substances, e.g. sugar, that are not classified as dangerous substances [1] or preparations that are not classified as dangerous preparations [2J. Other substances shall not be supplied with the toy.
The chemical substances and preparations listed in Table 1, in so far as they are classified as dangerous within the definitions contained in the above Directives, shall have their containers labelled accordingly (see
6.2).
5.1 General requirements
Chemistry sets shall be supplied with instructions for use (see Clause 8): a contents list with warnings and first aid information (see Clause 7); the equipment necessary for carrying out the experiments described in the instructions for use, eye protection (see 5.5): and if required a test tube stand (see 5,4).
Supplementary sets shall be supplied with a contents list as specified in Clause 7 and be marked in accordance with 6.3.3.
Ail experiments described shall be evaluated by the manufacturer. In particular, it shall not be possible for substances to be formed in amounts that are injurious to health,
NOTE Any known hazards ansirig from the use of the toy especially during the expenments should be detaded (e.g. handling of chemicals, handling of glassware. retarded boiling point, back flow of barrier water into overheated glassware, evolution of gases and handling of burners and other heating sources).
5.2 Containers and glassware
5.2.1 Test tubes
5.2.1.1 Sets in which test tubes are heated
In sets where the instructions for use include chemical experiments in which test tubes are heated, all test tubes shall be made of borosilicate glass in order to be heat resistant.
Glass test tubes intended to be heated shall have dimensions greater than 110 mm in length and 15 mm in internal diameter.
Glass test tubes not Intended to be heated e. g. not for chemical experiments may have dimensions not greater than 90 mm in length and 12 mm in internal diameter.
Borosilicate glass shall be tested in accordance with 5.2.6.
5.2.1.2 Sets in which test tubes are not heated
In sets, where the instructions for use do not include chemical experiments in which test tubes are heated and
the glass tubes are not made of borosilicate glass, all test tubes shall be labelled in accordance with 6.2.
5.2.2 Other glassware
In sets, where the instructions for use include experiments in which glassware are heated, all glassware intended to be heated shall be made of borosilicate glass in order to be heat resistant.
The above requirement does not apply to glass pipes intended to be heated for the purpose of bending.BS EN 71-4-2009 pdf download.
