European foreword
This document (prEN 71-17:2023) 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 xth 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

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:
— 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,

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 specific limit values for certain isothiazolinones in toys (see Commission
Directive (EU) 2015/2116 [2] and Directive (EU) 2015/2117 [3]). This European standard provides a
test method to check compliance with these limit values.
prEN 71-17:2023 (E)
1 Scope
This document specifies requirements and a test method for determining the content of certain
isothiazolinones in aqueous (toy) materials of toys intended 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.
