3.9 largest applicable test body largest of the three available standard sizes of test body (D9, D18 or D22) that is equal to or greater than the passenger height or weight limit specified by the manufacturer 3.10 visible crack crack which results from a test where that crack is visible to the naked eye 3.11 fracture unintentional separation into two or more parts 3.12 surface flash rapid spread of flame over the surface of a material without ignition of its base structure, reaching the first marker thread, which may or may not be severed, or either vertical edge of the test specimen [EN 1103:2005] 4 General test requirements 4.1 Classification of cycle trailers The classification of cycle trailers is given in Table 1. Table 1 — Types of cycle trailers Number of tracks For the transportation of: Childrena (C) Other loads (L) 1 (single track) —
— 2 (two tracks) C2b L2 a In case the cycle trailer is convertible into e.g. a stroller, see EN 1888. b EXAMPLE
Type C2 is a two track cycle trailer for the transportation of children and luggage.
For all cycle trailers, where the superstructures have a variable design, all combinations of equipment shall meet all relevant requirements. Accessories shall, if included by the manufacturer, be included in the tests. In cases where the test method allows an element of discretion on the part of the tester, the tester shall use his discretion to produce a situation which he considers most likely to result in a failure.
4.3 Order of tests The tests shall be performed in the following order: a) inspection test; b) dynamic test; c) static test. For the order of tests, see Annex C. 4.4 Tolerances
Unless stated otherwise, the tolerances given in Table 2 shall apply to nominal values. Table 2 — Tolerances
Tolerances Forces and torques 0 / + 5 % Masses and weights ± 1 % Dimensions ± 1 mm Angles ± 1° Time duration ± 5 s Temperatures ± 10 °C Pressures ± 5 % Speeds ± 5 % Accelerations ± 5 %
4.5 Test bodies The test bodies shall be designed as shown in Annex A. 4.6 Access zone for type C cycle trailers Fix the largest applicable test body in the cycle trailer seat. Remove all removable parts of the cycle trailer cover. Use the test arm and test leg fixed at the shoulder and at the thigh of the test body and determine which parts of the cycle trailer can be touched (see Figure 1). For the dimensions of the test arms and test legs, see Table A.1. SIST EN 15918:2011

Figure 1 — Determining the extent of the access zone 5 Materials 5.1 Chemical properties for type C cycle trailers (Migration of certain elements) All parts and components in the access zone (see 4.6) shall comply with the requirements in EN 71-3. NOTE Attention is drawn to all legal requirements concerning Dangerous Substances e.g. Regulation (EC) No 1907/2006, etc. This requirement does not apply to parts or components which due to their accessibility, function, mass, size or other characteristics, obviously exclude any hazard due to sucking, licking or swallowing, bearing in mind the foreseeable behaviour of children. 5.2 Flammability for type C cycle trailers Fabrics shall not produce a surface flash. Materials with a surface which produce surface flash on the approach of a flame shall not be used.
Surfaces showing no momentary area of flame in the area of the surface remote from the test flame are considered to meet this requirement. The test of the flammability shall be according to EN 1888. 6 Construction 6.1 General All tests shall be carried out at an ambient temperature of 23 °C. SIST EN 15918:2011

Cycle trailers with a total weight not exceeding 30 kg are exempted from this requirement. NOTE When the user connects the fully loaded trailer to any suitable cycle, it should not tend to lift the front wheel of the unloaded bicycle. 6.3 Deflection device Cycle trailers shall be designed such that a vertical obstacle cannot be caught between a wheel and the body of the cycle trailer when the cycle trailer is drawn forwards past any such obstacle. An example is shown in Figure 2.
Key 1 deflection devices 2
vertical obstacle 3
moving direction Figure 2 — Example of the deflection devices
The width of cycle trailer in front of the wheels shall not be less than the distance between the tyre centrelines and be shaped so that the cycle trailer is deflected sideways when drawn past a vertical obstacle (see Figure 2). 6.4 Hazardous edges and protrusions 6.4.1 Requirements All accessible edges and protrusions of the cycle trailer under all conditions shall be rounded or chamfered and free from burrs. All surfaces of the cycle trailer shall be free from burrs and sharp edges. SIST EN 15918:2011

The test method described in 4.6 shall be used to determine what is within the access zone. 6.6 Indirect contact with the wheels for type C cycle trailers 6.6.1 Requirements It shall not be possible for an occupant of a trailer to make a side panel touch a wheel.
Use the test method described in 6.6.2. 6.6.2 Test methods Use the test probe shown in Figure 3 and apply a force of 80 N from the inside of the passenger area into the side panels. Apply the force for 1 min.
Key 1 Hemispherical end
2 Diameter of 60 mm Figure 3 — Hemispherical probes, diameter of 60 mm
The probe shall have a diameter of 60 mm and a hemispherical end of radius 30 mm.
6.7 Front protection for type C cycle trailers 6.7.1 Requirements The type C cycle trailers shall be equipped with a barrier against small projectiles from the front. If the barrier has holes to permit ventilation, the size of the holes shall be smaller than 4 mm. SIST EN 15918:2011

Apply the force on 5 different places for 5 s each. An example of how to apply the probe is shown in Figure 4.
Figure 4 — Example for a mesh test 6.8 Entrapment for type C cycle trailers 6.8.1 Requirements There shall be no open ended tubes or apertures within the access zone of the vehicle (see 4.6) between 5 mm and 12 mm when measured in accordance with 6.8.2, unless the depth is less than 10 mm. 6.8.2 Test methods Check whether the 5 mm probe shown in Figure 5 when applied with a force of up to 30 N, enters 10 mm or more into the opening in any possible orientation. If the 5 mm probe enters 10 mm or more then the 12 mm probe (see Figure 5) shall also enter 10 mm or more with an applied force of up to 5 N. SIST EN 15918:2011

Key 1 Hemispherical end 2 Scribed line around circumference 3 Diameter 5 mm and 12 mm Figure 5 — Hemispherical probes, diameter of 5 mm and 12 mm 6.9 Small parts for type C cycle trailers In order to avoid ingestion or inhalation of small objects, detachable components within the access zone (see 4.6) shall not, without being compressed and whatever their orientation, fit entirely within the small parts cylinder shown in Figure 6. Dimensions in millimetres
Figure 6 — Small parts cylinder Non-detachable components within the access zone (see 4.6), i.e. those parts which are not intended to be removed, shall conform to one of the following: a) the components shall be so embedded that the child cannot grip them with its teeth or fingers; or b) the components shall be so fixed to the product that they cannot become detached when the torque and tensile tests are carried out in accordance with EN 71-1:2005+A9:2009, paragraphs 4, 5, 6 and 7 of 8.4.2.1, using the apparatus according to EN 71-1:2005+A9:2009, 8.4.1.1 and 8.4.1.2; or SIST EN 15918:2011

Any parts which become detached during any other tests required by this standard shall not, without being compressed and whatever their orientation, fit entirely within the small parts cylinder. 6.10 Folding mechanism 6.10.1 Requirements Locking devices are required to prevent a cycle trailer folding whilst a child is in the cycle trailer and also during the process of the child being put into and taken out of the cycle trailer. 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 the following: a) the locking mechanism shall be released by at least two consecutive acti
