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.

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.

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.

solution for each substance containing 1 000 mg/l in methanol (6.1.1) using appropriate pipettes and
volumetric flasks.
If d3-MIT (6.2.2.1) and/or d3-CIT (6.2.2.2) are purchased as solutions these are the stock solutions.
6.2.3.2 Intermediate solution 1 of internal standards
Prepare the intermediate solution 1 of the internal standards containing 200 mg/l d3-MIT (6.2.1.1) and
