Introduction
The purpose of this European Standard is to reduce the risk of accidents.
It is stressed that this European Standard cannot eliminate all possible risks to children using such a
product and that carer control is of paramount importance. Accidents are mainly due to carer(s) not
anticipating the extra reach and speed that children can achieve in the baby walking frame.
It is essential that all warnings and instructions specified in this standard are clearly given by the
manufacturer, to ensure that the baby walking frame can be used safely and correctly.

oSIST prEN 1273:2019

1 Scope
This document specifies safety requirements and test methods for baby walking frames into which a child
is placed, and intended to be used from when the child is able to sit up by itself until the child is able to
walk by itself.
This document does not apply to baby walking frames for therapeutic and curative purposes and to those
baby walking frames relying on inflatable parts to support the child.
Toys (e.g. ride on toys, push-along toys, usually intended for children able to walk unaided) are not
covered by this document.
If a baby walking frame has several functions or can be converted into another function the relevant
European standards apply to it.

8.6 Choking and ingestion hazard (see A.4.4)
8.6.1 Requirements
When tested in accordance with 8.6.2 any component or part of a component that is removed, whether
intended to be removed without the use of a tool or not, shall not fit entirely within the small parts
cylinder specified in 4.2.
8.6.2 Test methods
8.6.2.1 Assessment of child’s ability to grip components
A component is considered to be able to be gripped by a child if it can grip the component between its
thumb and forefinger or between its teeth.
Where it is difficult to assess whether a child can grip a component, establish whether it can be gripped
by inserting once the feeler gauge specified in 4.3 between the component and the underlying layer at an
angle between 0° and 10° from the surface of the underlying layer using a force of (10 ± 1) N. If the gauge
can be inserted more than 2 mm, the component is considered to be able to be gripped by the child.
8.6.2.2 Torque test
Apply a torque gradually to the component within a period of 5 s in a clockwise direction until either:
a) a rotation of 180° from the original position has been attained; or
b) a torque of 0,34 Nm is reached.
The maximum rotation or required torque shall be applied for (10 ± 1) s.
The component shall then be allowed to return to a relaxed condition and the procedure repeated in an
anticlockwise direction.
Where projections, components or assemblies are rigidly mounted on an accessible rod or shaft, designed
to rotate together with the projections, components or assemblies, during the test the rod or shaft shall
be clamped to prevent rotation.
If a component attached by a screw thread becomes loosened during application of the required torque,
the torque shall continue to be applied until the required torque is exceeded or the component
disassembles or it becomes apparent that the component will not disassemble.
When using clamps and test equipment, care shall be taken not to damage the attachment mechanism or
body of the component.
Check whether any component or part of a component that is removed during the test fits wholly in any
orientation, without compressing or manipulating it, within the small parts cylinder specified in 4.2.
8.6.2.3 Tensile test
The tensile test shall be carried out on the same components as the torque test.
Attach a suitable clamp to the component, taking care not to damage the attachment mechanism or body
of the component.

frame during the test, this shall not be considered as a failure.
8.10.2.2 Test method
8.10.2.2.1 General
Adjustable seats shall be adjusted to their highest position.
Unlock parking devices and any devices used to slow down the product (if any).
Establish a vertical plane A that passes through the centre of the seating area and is parallel to the
direction the child faces. Establish a vertical plane B that is perpendicular to plane A and passes through
the centre of the seating area.
The dynamic stability test shall be carried out in the forward (8.10.2.2.2) and rearward (8.10.2.2.3)
direction.
In case the forward and rearward directions are not evident, the baby walking frame shall be tested in
the most onerous forward direction allowed in the instructions for use and in its opposite rearward
direction.
8.10.2.2.2 Forward facing dynamic stability test
Position the baby walking frame on the test platform facing forward, so that plane A is perpendicular to
the front edge of the platform and passes through the centre of the pulley (4.7.3).
Position the test mass B (4.1.2) vertically in the centre of the seat.
The movement of the test mass during the test shall be minimized as far as possible by any appropriate
means of negligible mass.
Place a spacer (4.6.2) on the platform next to the stop. Move the baby walking frame towards the stop so
that the most protruding part(s) of the baby walking frame base touch(es) the squared aluminium
piece(s) thus keeping the most protruding part(s) of the baby walking frame base at a distance of 40 mm
from the stop. If one spacer is not high enough, add one more spacer on top of the previous one.
Attach test mass D (4.1.4) to the front of the baby walking frame base at plane A by means of a steel cable
(4.7.2) and a pulley (4.7.3) and adjust the pulley so that the force is applied horizontally.
The mass shall drop into a bucket containing sand. The surface of the bag shall be levelled to ensure that
the whole base area of the mass hits the surface of the bag filled with sand simultaneously.
Adjust the length of the steel cable so that the bottom surface of the test mass D just touches the surface
of the sand.
To fine tune the length of the steel cable, move the baby walking frame 10 mm to 20 mm from the
spacer(s) and release it in order to verify that, at this position, the tension of the steel cable is sufficient
to propel the baby walking frame forward. Remove the spacer(s) to verify that when the baby walking
frame is 40 mm from the stop the tension of the steel cable is not sufficient to propel the baby walking
frame forward.
NOTE The fine-tuning may have to be done in an iterative way.

When tested in accordance with 8.11.2 the baby walking frame shall maintain contact with and be
supported only by the test platform in each of the tests.
8.11.2 Test method
8.11.2.1 General
Clean the test platform and the underside of the base (e.g. wheels, stoppers) of the baby walking frame
with a cloth dampened with demineralized water. Let it dry before performing the tests.
Detachable toys shall be removed.
Position test mass B (4.1.2) vertically in the centre of the seat. The movement of the test mass inside the
seat shall not be restricted.
Establish a vertical plane A that passes through the centre of the test mass and is parallel to the direction
the child faces. Establish a vertical plane B that is perpendicular to plane A and passes through the centre
of the test mass.
Drill hole(s) in the base at a height of 60 mm from the test platform aligned with plane A at the front and
at the rear and plane B on both sides (see Figure 13). The hole(s) shall not affect the performance of the
product during the tests.
If the design of the product does not allow to drill the hole(s) as defined above, drill the hole(s) in the
base aligned with plane A and plane B as described above at a height as close as possible to 60 mm by
increments of ± 5 mm but not higher than 100 mm (see Figure 13). This only applies to the front, back or
side where it is not possible to drill the hole at 60 mm. If this applies only to the back of the product, for
example, then the holes on the front and the sides shall be at 60 mm.
If the design of the product does not allow to drill the hole(s) as defined above, attach a piece of steel
cable (see 4.7.2) wherever possible along the walking frame base at the same height defined above (see
Figure 14). This steel cable shall be fitted with an attachment device aligned with plane A or plane B as
relevant.
Additional holes may be required on the tray to fix the bar required for the tip over test (see 8.11.3).
