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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights
in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s)
which may be required to implement this document. However, implementers are cautioned that this may not
represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
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 136, Furniture.
This first edition cancels and replaces the second edition (ISO 9221-1:2015 and ISO 9221-2:2015), which have
been merged into one single document and has been technically revised.
The main changes are as follows:
— — ISO 9221-1:2015 and ISO 9221-2:2015 have been merged into one single document;
— complete review of the document in a hazard base format;
— addition of chemical and thermal hazards;
— addition of a dynamic strength test in 8.8.5;
— inclusion of specific requirements for high chairchairs with more than two castors/wheels in 8.11.1;
— improvement of restraint system requirements to require a passive crotch restraint for products with a
horizontal component in front of the baby in 8.9.1.1.
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 has been prepared in order to specify requirements and test methods intended to minimize
accidents to children resulting from normal use and reasonably foreseeable misuse of children’s high chairs.
The test methods are designed to evaluate properties without regard to materials, design/construction, or
manufacturing processes.

Furniture — Children's high chairs — — Safety requirements and test
methods
1 Scope
This document specifies safety requirements for free-standing children’s high chairs that elevate children to
dining table height, usually for the purposes of feeding or eating. Children’s high chairs are for children up to
3three years of age who are capable of sitting unaided.
With the exception of special high chairs for medical purposes, thisThis document appliesis applicable to
children'schildren’s high chairs for domestic and non-domestic use. It does not apply to special high chairs for
medical purposes.
NOTE If a children’s high chair is or can be converted into other functions, additional standards can apply.
