6 General requirements and test conditions
6.1 Number of passengers
The number of passengers is not limited but defined by the maximum gross vehicle weight as given in
EN 17860-2, EN 17860-3 and EN 17860-4.
6.2 Numbers and condition of specimens for the strength tests
In general, for static, impact and fatigue tests, each test shall be conducted on a new test sample, but if
only one sample is available, it is permissible to conduct all of these tests on the same sample with the
sequence of testing being fatigue, static and impact. When more than one test is conducted on the same
sample, the test sequence shall be clearly recorded in the test report or record of testing.
If more than one test is conducted on the same sample, earlier tests can influence the results of
subsequent tests. Also, if a sample fails when it has been subjected to more than one test, a direct
comparison with single testing is not possible.
In all strength tests, specimens shall be in the fully-finished condition.
6.3 Principles of the most onerous condition
Unless otherwise stated each test shall be conducted with the carrier cycle in the most onerous condition
for that test in terms of:
— the choice and number of seat(s) and/or infant carrier attached to the chassis stated in the
manufacturer's instructions;
— the addition of any additional seat(s) approved by the manufacturer;
— the weights of the passengers to be transported as specified by the manufacturer;
— the use of test masses: for carrier cycles transporting more than one child, at least one place that a
child can occupy shall be loaded with a test mass;
— the loading (or not) of any receptacle designed for carrying additional load(s) allowed for in the
instructions or otherwise approved by the manufacturer and the placing (or not) of load(s) in any
such facility, up to the maximum mass allowed in the manufacturer's instructions, or 2 kg if nothing
is indicated;
— the addition (or not) of any other accessories supplied or recommended by the manufacturer for use
with the carrier cycle and with accessories loaded according to the manufacturer’s instructions;
— the adjustment of seat(s), handles, infant carrier, and any other adjustable features (e.g. reclined
backrest) or accessories, or any other optional arrangement of the carrier cycle allowed in the
manufacturer's instructions or otherwise approved by the manufacturer.
NOTE The heaviest loads do not always produce the most onerous conditions.
6.4 Accuracy tolerances of test conditions for strength tests
Unless stated otherwise, accuracy tolerances based on the nominal values shall be as follows:
1) Forces and torques 0/+5 %
2) Masses and weights ± 1 %
3) Dimensions ± 1 mm
4) Angles ± 1°
5) Time duration ± 5 s
6) Temperatures ± 2 °C
7) Pressures ± 5 %
6.5 Fatigue test
The force for fatigue tests shall be applied and released progressively, not to exceed 10 Hz. The tightness
of fasteners according to manufacturer's recommended torque can be re-checked not later than
1 000 test cycles to allow for the initial settling of the component assembly. (This is considered applicable
to all components, where fasteners are present for clamping.) The test bench shall be qualified to meet
requirements of 6.4.
6.6 Fatigue test for composite components
For fatigue test for composite components, the initial value of displacement (peak-to-peak value) shall be
taken after 1 000 cycles and before 2 000 cycles.
6.7 Plastic material test ambient temperature
All strength tests involving any plastic materials shall be pre-conditioned for two hours and tested at an
ambient temperature of 23 °C ± 5 °C.
6.8 Crack detection methods
Standardized methods shall be used to emphasize the presence of cracks where visible cracks are
specified as criteria of failure in tests specified in this standard.
NOTE For example, suitable dye-penetrant methods are specified in EN ISO 3452-1:2021, EN ISO 3452-
2:2021 EN ISO 3452-3:2013 and EN ISO 3452-4:1998 In addition, white paint or surface treatment can be used to
aid in detection for composite materials.
7 General requirements for seats
7.1 General
The following requirements and corresponding test methods shall apply to the transportation of
passively transported passengers (i.e. not pedalling).
7.2 Passenger seating
7.2.1 General requirements
For passenger transportation, a suitable seat shall be available for each person to be transported in a
forward- or rearward-facing position.
See 6.3 for the principles of the most onerous conditions.
The seat shall be equipped with footrests. The floor of a transportation container equipped with a seat is
regarded as a footrest. The footrest shall prevent the risk of entrapment (e.g. the risk of a foot getting
stuck underneath the carrier cycle).
When tested by the test method described in 7.2.2 and 7.2.3, no crack in the seat surface and no visible
crack or fracture of another part shall occur in this case.
For Class C9 a suitable connector (Clause 12) shall be fitted for installation of an infant carrier in
rearward-facing position. All infant carriers that meet UN ECE 129/03 can be used for transporting a
Class C9 child. The manufacturer shall publish which models and brands of infant carrier(s) can be used
with the connectors.
7.2.2 Test method for dynamic loads
The test is conducted at all designed seating positions. If a seat is part of a combined construction of two
or more seats, for example a bench, then all seats shall be tested simultaneously.
The loading pad for the seat surface (see Figure 1) is applied centrally on the seat surface. The test load
is applied vertically downwards.
The defined force, F1, is applied by the loading pad for the seat surface(s) as defined in Table 3.
The loads are applied for a corresponding number of cycles as defined in Table 3.
Table 3 — Values for the dynamic seat test
Tests Force F1 Cycles
Fatigue life test on seat(s) permissible maximum specified 25 000

7.2.3 Test method for static loads
All adjustable backrests shall be moved to the most upright position.
The test is conducted at all designed seating positions. If a seat is part of a combined construction of two
or more seats, for example a bench, then these seats shall be tested simultaneously.
The loading pad for the seat surface is positioned centrally on the seat surface(s). The force (Fz) according
to Table 4 shall be applied vertically.
The loading pad for the backrest is applied either centrally onto the backrest or 100 mm beneath the top
edge of the backrest depending on which point is lower (see Figure 2). The force (Fx) according to Table 4
shall be applied horizontally.
The size of the loading pad for the backrest test may be altered when the manufacturer deems it more
suitable.

7.2.4 Requirements for armrests
If a carrier cycle for Class C22, C36 or Class A120 is equipped with armrests that are likely to be used as
a support for the body weight to enter or exit the carrier cycle the test in 7.2.5 shall be performed. No
visible crack or fracture shall occur.
7.2.5 Test method resistance to downward forces on the armrests
The downward forces to be applied to the armrests are in accordance with Table 5. With the cycle
standing on the horizontal test plane, set up a means for applying a vertical test force for each armrests.
Before commencing the test, set up the means to prevent the cycle from tipping and the means to prevent
the cycle from moving forward and backward.
Apply the load vertically to each armrests with a rectangular or cylindrical loading pad with dimensions
of Ø 50 mm x 150 mm) until the force is reached. Maintain the load for a period of 10 s ± 2 s. After that
remove the load.

7.2.6 Requirements for footrests
All seats shall be equipped with footrests.
The footrests shall be tested according to 7.2.7. When tested by the test method described in 7.2.7,
permanent deformation shall not exceed 2 mm.
7.2.7 Test method for the resistance to downward forces on the footrests
The downward forces to be applied to the footrest(s) are in accordance with Table 5. With the cycle
standing on the horizontal test plane, set up a means for applying a vertical test force for each footrest.
Before commencing the test, set up the means to prevent the cycle from tipping and the means to prevent
the cycle from moving forward and backward.
Apply the load vertically to each footrest with a rectangular or cylindrical loading pad 100 mm in
diameter, with a flat face and a 12 mm edge radius. Apply a static, pre-loading force of 100 N. Remove and
repeat this loading until a consistent deflection reading is obtained. Adjust the deflection measuring
device to zero.
Increase the static force to force determined in Table 5 and maintain this force for 60 s ± 2 s, then reduce
the force to 100 N and record any permanent deformation.
When it is allowed to transport more than one person that use the same footrest, multiply the test force
with the maximum number of passengers.
8 Ergonomics
8.1 General
The seating position shall be designed to the ergonomic principles set out in EN 614-1:2006+A1:2009.
It is recommended that the shape of the backrest allows for sufficient space for the child’s helmet.
Class C22: a measuring device defined in EN 14344:2022, Annex A shall be used to define the protected
volume for the child, check seat dimensions (see 8.4) and check the minimum angle between the seat and
the horizontal plane and the minimum angle between the seat and the backrest (see 8.4.3).
8.2 Determination of the protected volume
8.2.1 General
Protected volume is defined only for class C9 and class C22. Clause 8.2.2, describes the method to
determine the protected volume.
NOTE For independent child seats, refer to EN 14344:2022 for safety requirements and test methods.
8.2.2 Class C9 and C22
Class C9: the protected volume is defined by the sphere of the carrying handle of the infant carrier when
it is positioned in the connectors.
Class C22: when the paddings can be removed (for example for cleaning), the test shall be done with the
padding. Place the measuring device (EN 14344:2022, Annex A) into the seat then push the measuring
device against the backrest as shown in Figure 3 until it is in contact with the backrest (H). During the
positioning the four pins (G) shall always stay in contact with the seat.
— Mount on the measuring device the appropriate artificial shoulders and arms representing a child of
1 100 mm height in accordance with EN 14344:2022, Annex A Figure A.1.
— The assessment shall be done with the seat mounted in the most onerous positions taking into
account the instruction for use.
— Determine which part of the carrier cycle or any other accessories supplied or recommended by the
manufacturer for use with the carrier cycle can be reached by artificial arms of the measuring device.
If the seating position can be adjusted repeat the measurement in the most extreme seating positions.
A vertical band of 200 mm centred with the restrained system at the external rear surface of the backrest,
from the top of the backrest to the projection of the reference plane, is considered not to be accessible for
the child (see Figure 4 and Figure 5).

8.2.3 Classes C36 and A120
If the transportation of larger or heavier passengers is intended, the possibility of contact with the wheel
shall be determined using a test person of the smallest and of the largest size that fits in the seat while
sitting in the intended position with the feet on the foot rest.
The test persons shall be selected based on the size specifications in accordance with Table 6 and Figure 6
according to the 5th percentile female and the 95th percentile male.

8.3.1.1 Requirements Class C9 and C22
The roadway and all parts of the carrier cycle that move or rotate relative to it while the carrier cycle is
in motion shall not lie within the protected volume (e.g. drive train, brake, suspension).
Within the protected volume, no shear or squeeze points shall be located between moving parts which
can close to less than 12 mm unless the motion occurs while the carrier cycle is being erected, folded or
adjusted for use, or operated by the rider (e.g. while adjusting the backrest, fixation systems or brake
levers).
8.3.1.2 Requirements Class C36 and A120
The roadway and all parts of the carrier cycle that move or rotate relative to it while the carrier cycle is
in motion shall be prevented to lie within the protected volume.
If inherently to the function of the part a shear or squeeze point of less than 12 mm is inevitable this part
shall be equipped with a warning in the manual (e.g. storage compartment, door, spokes).
8.3.2 Folding mechanism
8.3.2.1 General
Folding mechanisms pose a hazard if parts of the body can enter a gap between parts and be trapped
when the gap is closed.
When operating a carrier cycle the folding mechanism shall stay locked and always fixed to prevent
unwanted movement of the cycle.
8.3.2.2 Requirements
Locking devices are required to prevent a folding mechanism, for frame or passenger compartment, from
folding whilst a passenger is entering, carried in or exiting a carrier cycle.
All locking devices for the folding mechanism shall be positioned so that it is not possible to operate more
than one device in a single action.
There shall be at least one locking mechanism which fulfils one of the following requirements:
1) the locking mechanism shall be released by at least two dependent actions, the second being
dependent on the first having been carried out and maintained, or;
2) the locking mechanism shall not be released or damaged in one single action during testing in
accordance with 8.3.2.3, or;
3) the locking mechanism is positioned outside the protected volume of the carrier cycle.
The locking devices shall not be released during the frame tests according to EN 17860-2:2024,
EN 17860-3:2024 and EN 17860-4:2025.
8.3.2.3 Test method
Place the carrier cycle on a horizontal flat surface.
Apply a force of 60 N (measured at 10 mm at the end in case of a lever) or a torque of 2,2 N m to the
locking mechanism. This force or torque shall be applied to the locking mechanism in the direction most
likely to release the locking mechanism in one single action. The force or torque shall be applied for a
period of 5 s. After this test check whether the locking mechanism has been released or damaged.
During the test and due to the test the folding mechanism shall not fold.
8.3.3 Hazardous edges and protrusions
8.3.3.1 Requirement
All accessible edges and protrusions within the protected volume shall be rounded or chamfered and
burr- free under all circumstances.
NOTE: EN 71-1:2014+A1:2018 8.11 and 8.12, describe test methods to assess sharp edges and protrusions.
8.3.3.2 Test method
All hazardous edges and protrusions shall be subjected to a visual inspection and tactile check.
8.3.4 Hazard of entrapment - holes and openings
8.3.4.1 Requirements
Holes in, and clearances between stationary parts that are accessible within the protected volume shall
be as specified in Table 7. This requirement is not applicable to the restraint system and the buckles of
the restraint system.
Table 7 — Safe distances between stationary parts
Safe distances Class C9 and C22
Finger traps Less than 7 mm or more than 12 mm
Foot traps Less than 25 mm or more than 45 mm
8.3.4.2 Test method
For finger traps check whether the 7 mm probe shown in Figure 7 when applied with a force of up to
30 N, enters 10 mm or more into the opening in any possible orientation. If the 7 mm probe enters 10 mm
or more then the 12 mm probe (see Figure 7) shall also enter 10 mm or more with an applied force of up
to 5 N.

Foot traps shall be measured with a round object that has the dimensions referred to in Table 7.
8.3.5 Hazard of choking and ingestion of small parts - Class C9 and C22
8.3.5.1 Requirements
The test applies only to components (including decals) within the protected volume of a Class C9 and
Class C22 seat.
When tested in accordance with 8.3.5.2.1 (ability to grip), 8.3.5.2.2 (torque test) and 8.3.5.2.3 (tension
test), 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, see Figure 8.

8.3.5.2 Test methods
8.3.5.2.1 Assessment of child’s ability to grip components
If the component to be tested cannot be gripped between thumb and forefinger, establish whether it is
grippable by inserting the feeler gauge, see Figure 9, between the component and the underlying layer or
body of the seat at an angle between 0° and 10° from the surface using a force of (10 ± 1) N. If the gauge
can be inserted more than 2 mm, the component shall be considered as grippable.

8.3.5.2.2 Torque test
Apply a torque gradually to the component over a period of 5 s ± 2 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 N m is reached.
The maximum rotation or required torque shall be applied for 10 s ± 2 s.
The component shall then be allowed to return to a relaxed condition and the test procedure is repeated
(from this position) 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 which is attached b
