DOWNLOAD EBOOK1 Scope 1.1 This standard specifies methods of sampling and digestion prior to analysis of the total concentration of the elements antimony, arsenic, barium, cadmium, chromium, lead, mercury, and selenium from toy materials and from parts of toys. Note: Other elements can be determined by this method provided adequate analytical performance is demonstrated. Manufacturers are encouraged to apply the test methods of this standard and the limits from GB 6675.4-2014 to raw materials used in the manufacture of toys to give increased certainty of conformity to the requirements of GB 6675.4-2014. 1.2 This standard is applicable to the following types of toy materials: ——coatings of paints, varnishes, lacquers, printing inks, polymers, and similar coatings; ——polymeric and similar materials, including laminates, whether textile-reinforced or not, but excluding other textiles; ——paper, paperboard and cardboard; ——natural or synthetic textiles; ——metallic materials whether coated or not; ——other materials, whether mass-coloured or not (e.g. wood, fibreboard, hardboard, bone, and leather); ——materials intended to leave a trace (e.g. the graphite materials in pencils and liquid ink in pens); ——pliable modelling materials, including modelling clays and gels; ——paints to be used as such in the toy, including finger paints, varnishes, lacquers, enamel powder and similar materials in solid or liquid form; ——packaging materials that form part of the toy or have intended play value. Note: Digestion methods for glass, ceramic, and other siliceous materials or fluorinated polymers or fluorinated polymer coatings are not described, and these types of materials are outside the scope of this standard (see Annex A, A.1).
