European foreword
This document (prEN 71-16:2023) 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 16th 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)
— Part 16: Certain chlorinated phosphorus flame retardants (TCEP, TCPP, TDCP) in toy materials (under
development) (the present document)
— 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)
— Part ee: Migration of bisphenol A from toy materials (under development)
prEN 71-16:2023 (E)
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 guidance documents have been published:
— CEN/TR 15071, Safety of toys — National translations of warnings and instructions for use in the EN 71
series,
— CEN/TR 15371 (all parts), Safety of toys — Interpretations,
— CEN/TR 16918, Safety of toys — Children's mouthing behaviour in contact with toys,
— CEN/TR 17695, Safety of toys - Mechanical and physical properties — Guidance on categorization of

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 June 2014 the European Commission amended Appendix C to Annex II to this Directive accordingly
and adopted specific limit values for TCEP, TCPP and TDCP in toys (see Commission Directive
2014/79/EU [2]). The limit values take into account the SCHER: Opinion on tris(2-
chloroethyl)phosphate (TCEP) in Toys [3].
This European standard provides a test method to check compliance with these limit values.
prEN 71-16:2023 (E)
1 Scope
This document specifies requirements and a test method for certain chlorinated phosphorus flame
retardants in toy materials. This document is applicable to toys intended for use by children under 36
months 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 [10] provides guidelines to help on the classification of toys intended for children under 36
months of age or of 36 months and over.

4 Requirements
The concentration of certain chlorinated phosphorus flame retardants in toy materials shall not exceed
the limits specified in Table 1 when tested according to Clause 7 and 8.
NOTE The limit values in Table 1 correspond to the limit values specified in Directive 2009/48/EC [1] which
were introduced by Commission Directive (EU) 2014/79 [2].

5 Principle
The sample is cut into small pieces and extracted with toluene at 60 °C in an ultrasonic bath. The extract
is analysed using a gas chromatograph with mass selective detector (GC-MS or GC-MS/MS).
