Safety of toys - Part 3: Migration of certain elements
This European Standard specifies requirements and test methods for the migration of aluminium, antimony, arsenic, barium, boron, cadmium, chromium (III), chromium (VI), cobalt, copper, lead, manganese, mercury, nickel, selenium, strontium, tin, organic tin and zinc from toy materials and from parts of toys.
Packaging materials are not considered to be part of the toy unless they have intended play value.
NOTE 1 See guidance document of the European Commission guidance document no. 12 [2] on the application of the Directive on the safety of toys – packaging.
The standard contains requirements for the migration of certain elements from the following categories of toy materials:
— Category I: Dry, brittle, powder like or pliable materials;
— Category II: Liquid or sticky materials;
— Category III: Scraped-off materials.
The requirements of this standard do not apply to toys or parts of toys which, due to their accessibility, function, volume or mass, clearly exclude any hazard due to sucking, licking or swallowing or prolonged skin contact when the toy or part of toy is used as intended or in a foreseeable way, bearing in mind the behaviour of children.
NOTE 2 For the purposes of this standard, for the following toys and parts of toys the likelihood of sucking, licking or swallowing toys is considered significant (see H.2 and H.3):
− All toys intended to be put in the mouth or to the mouth, cosmetics toys and writing instruments categorised as toys can be considered to be sucked, licked or swallowed;
− All the accessible parts and components of toys intended for children up to 6 years of age can be considered to come into contact with the mouth. The likelihood of mouth contact with parts of toys intended for older children is not considered significant in most cases (see H.2).

Introduction
The Toy Safety Directive (2009/48/EC) [1] specifies maximum migration limits for three categories of
toy materials. Certain limit values have been amended (see [4, 5, 6, 7]). The limits for the migration of
certain elements are expressed in milligram per kilogram toy material and are detailed in Table 2. The
purpose of the limits is to minimize children’s exposure to certain potentially toxic elements.

1 Scope
This document specifies requirements and test methods for the migration of aluminium, antimony,
arsenic, barium, boron, cadmium, Chromium (III), Chromium (VI), cobalt, copper, lead, manganese,
mercury, nickel, selenium, strontium, tin, organic tin and zinc from toy materials and from parts of toys.
Packaging materials are not considered to be part of the toy unless they have intended play value.
NOTE 1 See the European Commission guidance document no. 12 on the application of the Directive on the safety
of toys – packaging [2].
The standard contains requirements for the migration of certain elements from the following categories
of toy materials:
— Category I: Dry, brittle, powder like or pliable materials;
— Category II: Liquid or sticky materials;
— Category III: Scraped-off materials.
The requirements of this document do not apply to toys or parts of toys which, due to their accessibility,
function, volume or mass, clearly exclude any hazard due to sucking, licking or swallowing or prolonged
skin contact when the toy or part of toy is used as intended or in a foreseeable way, bearing in mind the
behaviour of children.
NOTE 2 For the purposes of this document, for the following toys and parts of toys the likelihood of sucking,
licking or swallowing toys is considered significant (see H.2 and H.3):
— All toys intended to be put in the mouth or to the mouth, cosmetics toys and writing instruments categorized
as toys can be considered to be sucked, licked or swallowed;
— All the accessible parts and components of toys intended for children up to 6 years of age can be considered
to come into contact with the mouth. The likelihood of mouth contact with parts of toys intended for older
children is not considered significant in most cases (see H.2).

The migration limit for Chromium (VI) for Category III toy material (scraped-off toy material) has been
amended by Commission Directive (EU) 2018/725 [7]. The new limit value (0,053 mg/kg) applies from 2019-
11-18. Before this date the limit value 0,2 mg/kg applies.
5 Principle
Soluble elements are extracted from toy materials using conditions which simulate the material
remaining in contact with gastric juices for a period of time after swallowing. The concentrations of the
soluble elements are determined quantitatively by three different methods:
— method for determining general elements: Aluminium, Antimony, Arsenic, Barium, Boron, Cadmium,
Chromium, Cobalt, Copper, Lead, Manganese, Mercury, Nickel, Selenium, Strontium, Tin and Zinc;
— method for determining Chromium (VI);
— method for determining organic tin.

NOTE This requirement does not preclude the preparation of test portions which represent the material and
any base material upon which it is deposited.
Analysis of toy materials present in amounts less than 0,010 g is not required (see H.5).
The above does not preclude the testing of toy materials before they are used to manufacture a toy (raw
materials). In these cases, the manufacturing process shall be assessed in order to ensure that it does not
influence the migration of elements from the toy materials.
7.2 Sample preparation
7.2.1 General
Appropriate blank solutions shall be analysed so that appropriate corrections can be made when
necessary (e.g. contamination of reagents and materials). If the blank result exceeds half of the lowest
value the laboratory intends to report (laboratory’s reporting limit) at least two blank solutions shall be
analysed and the analytical result shall be corrected by the average v
