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 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.

5 General requirements and test conditions
5.1 Product conditioning
Before testing, any fabrics used shall be cleaned or washed and dried twice in accordance with the
manufacturer’s instructions.
5.2 Test conditions
The tests shall be carried out in ambient conditions of (20 ± 5) °C.
The tests are designed to be applied to baby walking frames that are fully assembled and ready for use in
accordance with the manufacturer’s instructions. If the baby walking frame can be assembled or adjusted in
different ways in accordance with the manufacturer’s instructions, the most onerous combinations shall be
used for each test, unless otherwise specified in the test method.
5.3 Application of forces
The forces in the static load tests shall be applied sufficiently slowly to ensure that negligible dynamic effect
is applied.
5.4 Tolerances
Unless otherwise stated, the accuracy of the test equipment shall be as follows:

— Forces: ±5 % of the nominal force.
— Masses: ±0,5 % of the nominal mass.
— Dimensions: ±0,5 mm of the nominal dimension.
— Angles: ±0,5° of the nominal angle.
— Duration: ±1 s of the nominal duration.
The tests are described in terms of the application of forces. Masses can, however, be used. The relationship
10 N = 1 kg may be used for this purpose.
Unless otherwise specified, the test forces may be applied by any suitable device which does not adversely
affect the results.
5.5 Order of tests
Unless otherwise stated in the test methods, the tests shall be carried out on the same baby walking frame
in the order listed in this document.
6 Chemical hazards
6.1 General
Additional information on the background and rationale for various requirements is given in Annex A. In
general, the main materials used in baby walking frames are plastics or polymers, coatings, rubber, fabrics,
leather and artificial leather.
6.2 Requirements
6.2.1 General
The chemicals presented by material in Table 1 shall conform to the requirements in 6.3 to 6.7.

Fabric X X X X
Leather X X X
Fibreboard X X
Other materials X
NOTE  Other materials (e.g. paper and paperboard, wood, bamboo) are included, but metal, glass and ceramic are excluded.

6.2.3 S ampling
The sample for testing shall be representative of the material used in mass production. Identical materials
may be combined and treated as a single test portion. Test portions may be composed of more than one
material or colour only if physical separation, such as dot printing, patterned textiles or mass limitation
reasons, precludes the formation of discrete specimens.
The above sample requirement does not preclude the testing of materials before they are used to manufacture
(raw materials from manufacturing process).
The manufacturing process should ensure that it does not increase prohibited risk to the materials.
Where a surface is coated with a multi-layer of paint or similar coating, the test sample shall not include
any of the base material. Paint and other similar surface-coating material means a fluid, semi-fluid or other
material, with or without a suspension of finely divided colouring matter, which changes to a solid film when
a thin layer is applied to a metal, wood, leather, cloth, plastic or another surface.
NOTE If the composite materials (e.g. coated fabric) can be mechanically separated, the coating and fabric are
tested separately.
For migration of certain elements and phthalates tests, a test portion of less than 10 mg from a single
laboratory sample shall not be tested.
If the mass of the test portion from a single sample is greater than 10 mg but less than the normal mass for
testing, it is recommended to supplement the test materials as follows:
a) identical material from other locations of the same sample should be supplemented;
b) when sampling from raw materials: if raw materials are used instead of finished product, this should be
noted in the test report.
6.3 Migration of certain elements
The migration of elements from materials (see Table 1) on exterior surfaces shall not exceed the limits listed
in Table 2, considering the correction factor when tested in accordance with ISO 8124-3:2020.
Components under the base (e.g. castors or wheels, braking pads) are excluded from these requirements.

The test procedure given in ISO 14362-1 and ISO 14362-3 for fabric and ISO 17234-1 and ISO 17234-2 for
leather shall be used.
A test portion below 0,2 g in a single laboratory sample shall be exempted from test. All colours shall be
tested. Up to three colours may be combined as one specimen. ®
Azo colorants that are able to form 4-aminoazobenzene generate amines aniline (CAS Registry Number
62-53-3) and 1,4-phenylenediamine (CAS number 106-50-3) under the conditions of ISO 14362-1 and
ISO 17234-1. Due to detection limits, it is possible that only aniline is detected. If aniline of above 5 mg/kg
is detected, then the presence of these colorants shall be tested in accordance with ISO 14362-3 for fabric or
ISO 17234-2 for leather, which can release 4-aminoazobenzene.
So-called “white” and uncoloured fibres, threads or fabrics are not considered to contain azo colorants and,
therefore, these parts may be used without being tested. But attention should be paid to so-called “pale
printed” materials as they can contain azo colorants.
6.6 Formaldehyde
All accessible fabric and leather materials shall not release formaldehyde in excess of 20 mg/kg (see Table 5).
All fibreboard shall not release formaldehyde in excess of 0,124 mg/m (see Table 5).

Fabric and leather 20 mg/kg
Formaldehyde 50-00-0
Fibreboard 0,124 mg/m
For formaldehyde released from fabric and leather, the test procedure given in ISO 14184-1 for fabric and
ISO 17226-1 for leather shall be used.
Different types of fabrics shall be tested separately but the colour difference can be ignored. A test portion
below 1,0 g in a single laboratory sample shall be exempted from the test.
For formaldehyde released from fibreboard, the test procedure is defined in ISO 12460-1.
6.7 Flame retardants
Accessible plastics, artificial leather and fabrics of baby walking frames, which are not treated with flame
retardant, shall be exempted from flame-retardant testing. Only a declaration of conformity document is
required. The template of declaration of conformity for flame retardants defined in ISO 31110:2020 (see
Clause A.5) can be used for reference.
Accessible plastics, artificial leather and fabrics in the baby walking frames, which are treated with flame
retardant, shall not contain the flame retardants listed in Table 6 according to the limits given in Table 6.

7 Thermal hazards (see Clause B.2)
7.1 Requirement
The rationale for requirements on thermal hazards is given in Annex B. When tested in accordance with
7.2, there shall not be a surface flash and the rate of spread of flame on textile materials shall not exceed
50 mm/s.
These tests can be performed on a separate sample, conditioned according to 5.1, or at the end of the test
sequence.
7.2 Test method
To verify the surface flash effect, apply the test flame defined in ISO 8124-2:2023, 5.5, for (3 ± 0,5) s to the
baby walking frame in different places likely to cause surface flash.
To verify rate of spread of flame, apply the test flame defined in ISO 8124-2:2023, 5.4.
8 Mechanical hazards (see Clause B.3)
8.1 General
The background information and rationales for various requirements on mechanical hazards are given in
Annex B.
8.2 Entrapment hazards (see B.3.1)
8.2.1 Requirements
When tested in accordance with 8.2.2, there shall not be any completely bounded openings between 7 mm
and 12 mm unless the depth is less than 10 mm or unless the shape assessment probe (4.3.2) enters when
tested in accordance with 8.2.2.
When tested in accordance with 8.2.2, there shall not be any openings in mesh that allow the test probe for
mesh (4.3.1) to penetrate to the 7 mm diameter section.
The test shall be carried out with the product in any intended position of use.
This requirement does not apply to the castors, wheels, the whole base of the baby walking frame, and to
any other part of the underside of the tray more than 100 mm from the vertical projection of the outer edge
(see Figure 12).

8.2.2 Test methods
Check whether the 7 mm probe (4.3.1), with an applied force of up to 30 N, enters 10 mm or more into any
accessible completely bounded opening in any possible orientation.
If the 7 mm probe enters 10 mm or more, then the 12 mm probe (4.3.1) shall also enter 10 mm or more with
an applied force of up to 5 N.
