European foreword
This document (prEN 71-15:2023) has been prepared by Technical Committee CEN/TC 52 “Safety of
toys”, the secretariat of which is held by DS.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States
For relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
Additional information on the background and rationale for various requirements are given in Annex A.
This document constitutes the 15th part of the EN 71 series of standards on safety of toys.
EN 71, Safety of toys, consists of the following parts:
— Part 1: Mechanical and physical properties
— Part 2: Flammability
— Part 3: Migration of certain elements
— Part 4: Experimental sets for chemistry and related activities
— Part 5: Chemical toys (sets) other than experimental sets
— Part 7: Finger paints — Requirements and test methods
— Part 8: Activity toys for domestic use
— Part 10: Organic chemical compounds — Sample preparation and extraction
— Part 11: Organic chemical compounds — Methods of analysis
— Part 12: N-Nitrosamines and N-nitrosatable substances
— Part 13: Olfactory board games, cosmetic kits and gustative games
— Part 14: Trampolines for domestic use
— Part 15: Formamide in foam toy materials (under development) (the present document)
— Part bb: Certain chlorinated phosphorus flame retardants (TCEP, TCPP, TDCP) in toy materials (under
development)
— Part cc: Certain isothiazolinones (MIT, CIT, BIT) in aqueous toy materials (under development)
— Part dd: Phenol in aqueous (content) and polymeric (migration) toy materials (under development)
prEN 71-15:2023 (E)
— Part ee: Migration of bisphenol A from toy materials (under development)
It is up to the user of the standard to determine whether or not a toy is included in the scope of several of
the above parts of the EN 71-series, and to apply each applicable standard accordingly. Normative
references from one part of the EN 71-series to another, are therefore normally not provided in the
individual parts.
NOTE 1 In addition to the above parts of EN 71, the following deliverables have been published:

series,

Introduction
According to article 46 of Directive 2009/48/EC on the safety of toys [1] the “Commission may adopt
specific limit values for chemicals used in toys intended for use by children under 36 months or in other
toys intended to be placed in the mouth”.
In November 2015 the European Commission amended Appendix C to Annex II to this Directive
accordingly and adopted a specific limit value for formamide in toys (see Commission Directive (EU)
2015/2115 [2]). This European standard provides a test method to check compliance with the limit value
(cut-off limit based on content).
prEN 71-15:2023 (E)
1 Scope
This document specifies requirements and a test method for determining the content of formamide in
foam toy materials. The document is applicable to toys for use by children under 36 month or intended
to be placed in the mouth.
NOTE The European Commission Guidance Document No 11 on the Application of Directive 2009/48/EC on
the Safety of Toys [4] provides guidelines to help on the classification of toys intended for children under 36 months
of age or of 36 months and over.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
• IEC Electropedia: available at https://www.electropedia.org/
• ISO Online browsing platform: available at https://www.iso.org/obp
3.1
foam toy material
plastic whose density is reduced by the presence of numerous small cavities (cells), interconnected or
not, dispersed throughout the material
[SOURCE: IEC Electropedia, definition 212-15-24]
3.2
sample
part of the foam toy material subject to testing
4 Requirements
The concentration of formamide in foam toy materials shall not exceed 200 mg/kg.
NOTE This limit corresponds to the limit value specified in Directive (EU) 2009/48 [1] which was introduced
by Commission Directive (EU) 2015/2115 [2].
5 Principle
The sample is cut into small pieces and subsequently extracted with acetone at 70 °C using an ultrasonic
bath. The extract is analysed by gas chromatography with mass selective detector (GC-MS).

6.2.3 Stock solution of internal standard
Prepare a stock solution containing 5 g/l N,N-Dimethylformamide-d7 (6.2.2) in acetone (6.1.1) by
dissolving 100 mg of N,N-Dimethylformamide-d7 (6.2.2) in a 20 ml volumetric flask (6.3.4) with acetone
(6.1.1) and diluting to volume with acetone (6.1.1). This solution shall be stored in the absence of light at
(5 ± 3) °C.
6.2.4 Solutions of calibration standard

Prepare an intermediate solution containing 10 mg/l formamide (6.2.1) by diluting the stock solution of
formamide (6.2.4.1). 200 µl of the stock solution of formamide (6.2.4.1) are transferred to a 20 ml
