7/F, No.15, Chifeng Road, Licheng Region, Quanzhou city of Fujian PR,China.On April 2019, the European Committee for Standardization (CEN) published a new version of European standard EN 71-3:2019, Safety of toys - Part 3: Migration of certain elements. This standard will be given the status of a national standard and the conflicting national standards will be withdrawn by October 31, 2019 at the latest.
The current harmonized standard for the migration of specific elements of the EU Toy Safety Directive is EN 71-3:2013+A3:2018. But EN 71-3:2019 is expected to be harmonized under the Toys Safety Directive (2009/48/EC) when accepted by the European Commission (EC) and published in the Official Journal of the European Union (OJEU).
Significant technical changes between this Standard and the previous version:
Clause
Change
3 Terms and definitions
New terms and definitions for sample and laboratory sample added and terms and definitions on limit of detection, limit of quantification and other material (whether mass coloured or not) removed
4.2 Specific requirements
The migration limit for Chromium (VI) for Category III toy material (scraped-off toy material) in table 2 has been amended form 0,2 mg/kg to 0,053 mg/kg, and the new limit value applies from 2019- 11-18
6.2.6 Membrane filters
Delete membrane filters with pore sizes of 0,22 μm, add note: syringe filters made with a cellulose acetate membrane are recommended for the 0,45 μm filter
7 Sampling and sample preparation
The clause 7 sample preparation of old version was split into clause 7 Sample Preparation and clause 7 Migration methodology in the new version
8 Migration methodology
7.2.2 Sampling
Sampling and sample preparation have been revised and restructured to improve the user-friendliness of the standard. In particular sieving is no longer required and the corresponding annex with sieve requirements (former Annex C) has been deleted. Furthermore, the dewaxing procedure has been revised
8.2.3 pH adjustment
The migration procedure has been revised and more detailed procedures for checking the pH before and after migration has been introduced.
9 Stabilization and analysis of migration solutions
The stabilization of the migration solution has been revised. The status of test methods (included in Annex E, Annex F and Annex G) has been changed to normative. Performance requirements concerning the use of modifications to the annexes and alternatives to the specified test methods have been introduced
10 Calculation of results
The calculation has been revised, in particular Chromium (III) is now calculated by subtracting the Chromium (VI) concentration from the total chromium concentration
11 Method performance
Data on method performance have been introduced based on the results of test method validation and in particular the results of an inter laboratory comparison
Annex B
A new informative annex containing information on the method development has been introduced
Annex C
A new informative annex with estimations of reproducibility has been added
Annex D
A new annex concerning the use of visual particle size comparison materials has been added
Annex E
Minor revisions of the test method for general elements have been made
Annex F
The test method for Chromium (III) and Chromium (VI) has been replaced by a test method for Chromium (VI) which is capable of determining Chromium (VI) at the limit values for all material categories
Annex G
The test method for organic tin has been revised
Annex H
Various rationales have been revised and new rationales concerning sampling and dewaxing have been added
