Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso
.org/iso/foreword .html.
This document was prepared by Technical Committee ISO/TC 181, Safety of toys.
This second edition of ISO 8124-6 cancels and replaces the first edition (ISO 8124-6:2014), which has
been technically revised.
The main changes to the previous edition are as follows:
— addition of di-iso-butyl phthalate (DIBP) in Clause 1 and Annex A;
— addition of liquid material in Clause 1, Clause 7 and Annex A;
— addition of a new Clause 2, Normative references, and renumbering of subsequent clauses;
— addition of a new method C, “ultrasonic bath method”;
— update and reorganization of the inter-laboratory collaborative trial test data in Annex B;
— addition of a new Annex E, Ultrasonic bath performance check, and renumbering of all annexes.
A list of all parts in the ISO 8124 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/members .html.

Introduction
This document is largely based upon the existing Chinese national standard GB/T 22048-2008. Relevant
standards of some countries and regions are referred to as well.
This document does not set out limits for phthalate esters. It is intended to be used as a method
standard in conformity assessment. The user of this document is therefore advised to be aware of
relevant national requirements.
In some countries phthalate ester requirements for toys are also applicable to children’s products and
children’s product materials are generally similar to those of toys. This document, whose scope covers
various materials, is therefore applicable to both toys and children’s products.
Annex A and Annex E are normative, whereas Annex B, Annex C, Annex D, Annex F and Annex G are for
information only. However, they are crucial and helpful for the correct interpretation of this document.
INTERNATIONAL STANDARD ISO 8124-6:2018(E)
Safety of toys —
Part 6:
Certain phthalate esters in toys and children's products
WARNING — Persons using this document should be familiar with normal laboratory practice.
This document does not purport to address all of the safety problems, if any, associated with its
use. It is the responsibility of the user to establish appropriate safety and health practices.
IMPORTANT — It is absolutely essential that tests conducted in accordance with this document
be carried out by suitably trained staff.
1 Scope
This document specifies a method for the determination of di-iso-butyl phthalate (DIBP), di-n-butyl
phthalate (DBP), benzylbutyl phthalate (BBP), bis-(2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate
(DNOP), di-iso-nonylphthalate (DINP) and di-iso-decyl phthalate (DIDP) (as specified in Annex A) in
toys and children’s products.
This document is applicable to toys and children’s products which are made of plastics, textiles, coatings
and liquids. This document has been validated for polyvinylchloride (PVC) plastics, polyurethane (PU)
plastics and some representative paint coatings (see Annex B). It might also be applicable to other
phthalate esters and other product materials provided that adequate validation is demonstrated.
