in accordance with 8.3.3.2.3.
8.3.3.2.3 Partially bound, V and irregular shaped openings
Position the ‘B’ portion of the test template (see 4.7.3) between and perpendicular to the boundaries of
the opening, as shown in Figure 16 or Figure 17, as appropriate. If the full thickness of the template
cannot be inserted there is no hazard (Key 1 and 2 of Figure 16 and Key 1 of Figure 17).
If the test template can be inserted to a depth greater than the thickness of the template (45 mm) (Key 3
and 4 of Figure 16 and Key 2 of Figure 17), apply the ‘A’ portion of the test template, so that its centre line
prEN 12221:2023 (E)
is in line with the centre line of the opening. Ensure that the plane of the test template is parallel and
applied in line with the opening, as shown in Figure 18. Insert the test template along the centre line of
the opening until its motion is arrested by contact with the boundaries of the opening. If the template
touches the bottom of the opening there is no hazard (Key 1 of Figure 18), but if the sides of the template
touch the side of the opening there is a hazard (Key 2 of Figure 18).

8.4 Hazards due to moving parts (see A.4.4)
8.4.1 Requirements for compression points
After the product has been set up for use in accordance with the manufacturer’s instructions, there shall
be no accessible compression points, within the protected volume, which can close to less than 12 mm
unless they are always less than 5 mm, as the result of:
a) the movement of the product; or
b) the movement of body weight by the child using the product; or
c) the application of an external force (either unintentionally by the carer, or by a powered mechanism).
Movement due to elasticity of materials shall not be considered as compression hazard.
The area of contact between the changing pad / changing unit accessory and the surface on which the
changing pad / changing unit accessory is attached is excluded from this requirement.
prEN 12221:2022 (E)
8.4.2 Requirements for shear points
After the product has been set up for use in accordance with the manufacturer’s instructions, there shall
be no accessible shear points, within the protected volume, which can close to less than 12 mm, as the
result of:
a) the movement of the product; or
b) the movement of body weight by the child using the product; or
c) the application of an external force (either unintentionally by the carer, or by a powered mechanism).
Movement due to elasticity of materials or play in mechanical parts shall not be considered as a shearing
hazard.
The area of contact between the changing pad / changing unit accessory and the surface on which the
changing pad / changing unit accessory is attached is excluded from this requirement.
8.5 Hazards due to falling of the child (see A.4.5)
8.5.1 General
The product shall not be fitted with any means to restrain the child (e.g. harness system or belts).
No toy(s) or toy bar shall be fitted or provided for the product. In case of multifunctional products, this
requirement applies only to the changing unit function.
8.5.2 Barriers
8.5.2.1 Requirements
8.5.2.1.1 Dimensional requirements
Barriers shall be provided as an integral part of the changing unit / changing pad / changing unit
accessory or by means of an additional item, e.g. barrier pad that can be affixed to the changing unit.
a) if w is greater than l and greater than 600 mm then the changing area shall have barriers on three
sides of the changing area covering at least 75 % of l (see Figure 19), when measured in accordance
with 8.5.2.2.1;
b) if l is greater than w the changing area shall have barriers on two sides of the changing area covering
at least 90 % of l (see Figure 20), when measured in accordance with 8.5.2.2.1.
Where w is the width of the changing area (see 8.2.1) and l is the length of the changing area (see 8.2.1).
For wall-mounted units, the wall is to be considered as a barrier for this side.
8.5.2.1.2 Performance requirements
When tested in accordance with 8.5.2.2.2, the barriers of the changing unit / changing pad / changing
unit accessory shall not become damaged or loosened, nor shall the test mass fall from the changing area.
Changing pads sold alone and failing the barrier performance test shall meet one of the following
conditions:
a. the changing pad cannot be sold as suitable for use on changing units or elevated surface and shall
bear the warning according to 9.2.1 (e).
prEN 12221:2023 (E)
b. the changing pad is suitable for use on changing units with a minimum height of barriers: it shall be
tested on a changing unit or a test rig (see 4.17) having the minimum height of barriers in accordance
with manufacturer’s instructions.
8.5.2.2 Test methods
8.5.2.2.1 Test method for measurement of length of barriers
The length of the barrier (l ) is measured as the length of the barrier in contact with the flat changing area
(see Figure 19 and 20).

8.5.2.2.2 Test method for barriers performance
The following considerations in Table 3 are to be considered for changing pads:
Table 3 — Type of changing pad and test conditions
Type of changing pad Test conditions
a) The changing pad is provided with the Test only with the changing pad
changing unit:
1) the changing pad is an integral part of the
changing unit and the changing unit
cannot be used without the changing pad
a) The changing pad is provided with the Test with and without the changing pad
changing unit:
2) the changing pad is removable and the
changing unit can be used without the
changing pad
b) There is no changing pad sold with the Test with and without the specific recommended
changing unit changing pad.
1) The manufacturer recommends a specific If the changing pad is the accessory required to
changing pad transform another product (e.g. a cupboard) into
a changing unit, then the test is done only with the
changing pad (the other product alone would not
be a changing unit).
b) There is no changing pad sold with the Test the changing unit without the changing pad
changing unit
2) The manufacturer recommends a generic
changing pad by giving only dimensional
constraints
c) Changing pads sold alone Test the changing pad by itself.
Place the changing unit / changing pad / changing unit accessory on an inclined surface at 15° (+ 0,5°/0°)
to the horizontal and put stops against all legs or supports to prevent it overturning.
NOTE 1 If relevant, the changing unit accessory is attached to the product it is intended to be used with.
NOTE 2 Wall mounted changing units are tested not fixed to the wall as this would not allow to incline them.
Place test mass B (see 4.2) on the changing unit / changing pad or test mass A (see 4.1) on the changing
unit accessory in such a way that the test mass rests against the barrier to be tested and its turning axis
lies parallel to the barrier to be tested (see Figure 21).

Figure 21 — Effectiveness of barriers
Roll the test mass away from the barrier and release it when its longitudinal axis is aligned with, and at a
distance of 260 mm from its rest position against the barrier or up to the opposite barrier if the width is
not enough to move it to 260mm.
Test each single barrier in the middle and on each side, with the external side of the test mass flush with
the external end of the barrier (see Figure 22).
A barrier is considered to be a single barrier when it is made of a continuous material (e.g. a curved
shaped single piece of foam or a curved single milled piece of wood).
