1 Scope
1.1 This part of GB 6675 specifies maximum acceptable levels and methods of sampling and extraction prior to analysis for the migration of the elements antimony, arsenic, barium, cadmium, chromium, lead, mercury and selenium from toy materials and from parts of toys.
1.2 Maximum acceptable levels are specified for the migration of the elements listed in 1.1 from the following toy materials:
— coatings of paints, varnishes, lacquers, printing inks, polymers and similar coatings (see 8.1);
— polymeric and similar materials, including laminates, whether textile-reinforced or not, but excluding other textiles and non-woven textiles (see 8.2);
— paper and paperboard, up to a maximum mass per unit area of 400 g/m2 (see 8.3);
— natural, artificial or synthetic textiles (see 8.4);
— glass/ceramic/metallic materials, excepting lead solder when used for electrical connections (see 8.5);
— other materials, whether mass-coloured or not (e.g. wood, fibreboard, hardboard, bone and leather) (see 8.6);
— materials intended to leave a trace (e.g. the graphite materials in pencils and liquid ink in pens) (see 8.7);
— pliable modelling materials, including modelling clays and gels (see 8.8);
— paints to be used as such in the toy, including finger paints, varnishes, lacquers, glazing powders and similar materials in solid or liquid form (see 8.9).
