GB 6675.4-2025 Safety of toys - Part 4: Migration of certain elements
Warning: Persons using this document shall be familiar with normal laboratory practice. This document does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions.
1 Scope
1.1 This document specifies maximum acceptable levels and methods of sampling, specimen preparation and extraction, and determination for the migration of the elements antimony, arsenic, barium, cadmium, chromium, lead, mercury, selenium and boron from toy materials and from parts of toys.
1.2 The requirements for maximum acceptable levels of migrated elements specified in this document is applicable to the following toy materials:
—— coatings of paints, varnishes, lacquers, printing inks, polymers and similar coatings (see 8.1);
—— polymeric and similar material, including laminates, whether textile-reinforced or not, but excluding other textiles and non-woven textiles (see 8.2);
—— paper and paperboard (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);
Note: Stone, gemstone and similar materials are classified as glass/ceramic/metal materials.
—— other materials, whether mass-colored or not (e.g. wood, fibreboard, hardboard, bone and leather) (see 8.6);
—— materials intended to leave a trace [including the graphite materials in pencils and colored or colorless liquid materials (e.g., liquid ink and bubble water in pens)] (see 8.7);
—— pliable modelling materials, including modelling clays, putties, slimes and gels (see 8.8);
—— paints to be used as such in the toy, including finger paints, varnishes, lacquers, glazing powders and similar material in solid or liquid form (see 8.9).
1.3 The requirements in this document apply to the following toys, toy components of toys, and toy materials (see A.2.1):
—— all intended food and oral contact toys, cosmetic toys and writing instruments categorized as toys, irrespective of any age grading or recommended age labelling;
—— all toys intended for or suitable for children under 72 months of age;
—— accessible coatings, irrespective of any age grading or recommended age labelling;
—— accessible liquids, pastes and gels (e.g. liquid paints, modelling compounds), irrespective of any age grading or recommended age labelling.
1.4 Packaging materials are not included, unless they are intended to be kept, for example boxes and containers, or unless they form part of the toy or have intended play value (see A.2.2). This document does not apply to plant seeds.
Note: No requirements are given for toys and parts of toys which, due to their accessibility, function, mass, size or other characteristics, are obviously unlikely to be sucked, licked or swallowed, bearing in mind the normal and foreseeable behaviour of children (e.g. the coating on the crossbeam of a swing set, the tyres of a toy bicycle).

3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
3.1
base material
material upon which coatings may be formed or deposited
3.2
coating
layers of material formed or deposited on the base material of a toy
Note: It includes paints, varnishes, lacquers, inks, polymers, or other substances of a similar nature, whether they contain metallic particles or not, no matter how they have been applied to the toy, and which may be removed by scraping with a sharp blade.
3.3
method detection limit; MDL
three times the standard deviation of the result obtained in the method blank by the laboratory carrying out the analysis
3.4
mass-coloured material
materials that absorb coloring substances but do not form a coating
Note: Such as wood, fiberboard, cardboard, leather, bones and other loose materials.
3.5
paper
sheet formed by irregularly intervened cellulose fibres with a mass per unit area of 400 g/m² or less
Note: If paper with polymeric lamination, or other treatments which may be resistant to wetting, no longer presents the same properties as paper, then it is not treated as such.
3.6
paperboard
sheet formed by irregularly intervened cellulose fibres with a mass per unit area over 400 g/m²
Note 1: The term paperboard also includes materials commonly referred to as card or cardboard with a mass per unit area over 400 g/m ², and excludes pressed wooden fibreboards such as medium density fibreboard (MDF), chipboard and materials with similar properties.
Note 2: If paperboard with polymeric lamination, or other treatments which may be resistant to wetting, no longer present the same properties as paper, then they are not treated as such.
3.7
scraping
mechanical process for removal of coatings down to the base material
3.8
accessible
part or component of a toy can be accessed by any part in front of the shaft shoulder of the accessible probe shaft described in the accessibility test of toy part or component in GB 6675.2
3.9
toy material
accessible material present in a toy
3.10
slime and similar toy
transparent or colored water-based gels or similar gel-like materials
Note 1: It also includes various materials intended for children or with children as an important user group for making slime and similar toys.
Note 2: This material is viscous, smooth and usually a non-Newtonian fluid. It can be operated by hand, kneaded and stretched into different shapes. The material behaves in a non-Newtonian fluid state. When subjected to shear stress (such as when operated by hand), its viscosity changes, either becoming better or worse. When the shear stress is stopped, this viscosity can return to its original state.
Note 3: For slime powder materials in toys (materials made into slime after adding water in proportion), the test for migration of specific elements is carried out according to this document after making slime as specified in the instructions for use.
