Child care articles — Baby walking frames — Safety requirements and test methods

This document specifies safety requirements and test methods for baby walking frames into which a child is placed, and which are intended to be used from when the child is able to sit up unaided (around six months), until the child is able to walk independently or weighs more than 12 kg. This document does not apply to: — baby walking frames: — for therapeutic and curative purposes; — that rely on inflatable parts to support the child; — toys (e.g. ride on toys and push-along toys usually intended for children able to walk unaided). If a baby walking frame has several functions or can be converted into another function, then the relevant International Standards apply to it. For example, if a baby walking frame is equipped with toys, the requirements of the ISO 8124 series apply to the toys.

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.

Introduction
The purpose of this document is to reduce the risk of death and injury when using baby walking frames. It is
stressed that this document cannot eliminate all possible risks to children using such a product and that carer
control is of paramount importance.
Conformity to the requirements of this document will minimize potential hazards associated with using baby
walking frames.
This document is largely based on the existing European standard EN 1273:2020+A1:2023. The differences
between EN 1273:2020+A1:2023 and this document are as follows:
— chemical requirements in Clause 6;
— product information requirements in 9.1 and 9.4.

Child care articles — Baby walking frames — Safety requirements and
test methods
1 Scope
This document specifies safety requirements and test methods for baby walking frames into which a child is
placed, and which are intended to be used from when the child is able to sit up unaided (around 6 six months),
until the child is able to walk independently or weighs more than 12 kg.
This document does not apply to:
— baby walking frames:
— for therapeutic and curative purposes;
— that rely on inflatable parts to support the child;
— toys (e.g. ride on toys and push-along toys usually intended for children able to walk unaided).
If a baby walking frame has several functions or can be converted into another function, then the relevant
International Standards apply to it. For example, if a baby walking frame is equipped with toys, the toys should
comply with the requirements of the ISO 8124. series apply to the toys.
