Cycles - Cycle trailers - Safety requirements and test methods
This European standard specifies safety requirements and test methods for two track cycle trailers (i.e. with one or two wheels) and their connecting devices.
These cycle trailers are intended for the conveyance of cargo loads or up to two passive child passengers (i.e. not pedalling), both of whom are capable of sitting unaided and neither of whom weighs more than 22 kg.
The maximum permitted weight of such a cycle trailer, including cargo and/or passenger(s), does not exceed 60 kg.
This standard is not applicable to trailer cycles (one or two-track trailer for the transportation of one or two pedalling passengers, usually children, with device for connection behind cycle) and for type L trailers for professional use or with a single wheel (single track trailer) according to Table 1.
Fahrräder - Fahrradanhänger - Sicherheitstechnische Anforderungen und Prüfverfahren
Diese Europäische Norm legt sicherheitstechnische Anforderungen und die entsprechenden Prüfverfahren für zweispurige Fahrradanhänger (das heißt mit einem oder zwei Rädern) und deren Verbindungseinrichtungen fest.
Diese Fahrradanhänger sind für die Beförderung von Nutzlasten oder von bis zu 2 Kindern als passiv beförderte Personen bestimmt (das heißt nicht tretend), von denen beide ohne fremde Hilfe sitzen können und keines mehr als 22 kg wiegt.
Das zulässige Höchstgewicht eines solchen Fahrradanhängers, einschließlich der Last und/oder der beförderten Person(en), liegt bei 60 kg.
Diese Norm gilt nicht für Anhängerfahrräder (ein- oder zweispuriger Fahrradanhänger für die Beförderung von ein oder zwei tretenden Personen, üblicherweise Kinder, mit einer Vorrichtung zur Anbringung hinter einem Fahrrad) und für Typ-L-Anhänger für den beruflichen Gebrauch oder mit einem einzelnen Rad (einrädriger Anhänger) entsprechend Tabelle 1.
Cycles - Remorques pour cycles - Exigences de sécurité et méthodes d'essai
La présente Norme européenne spécifie des exigences de sécurité et des méthodes d'essai pour les remorques pour cycle à deux voies (c'est-à-dire à une ou deux roues) et leurs dispositifs d'attelage.
Ces remorques pour cycle sont destinées au transport de charges ou jusqu'à deux enfants passifs (ne pédalant pas) capables de se tenir assis sans aide dont aucun ne pèse plus de 22 kg.
La masse maximale autorisée d'une telle remorque pour cycle, charge et/ou passager(s) compris, ne dépasse pas 60 kg.
La présente norme n'est pas applicable aux vélos remorqués (remorque à une ou deux voies avec dispositif d'attelage derrière un cycle pour le transport d'un ou deux passagers pédalant, habituellement des enfants) ni aux remorques de type L pour usage professionnel ou à une seule roue (remorque à une seule voie) conformément au Tableau 1.
Kolesa - Prikolice za kolesa - Varnostne zahteve in preskusne metode
Ta evropski standard določa varnostne zahteve in preskusne metode za dvotirne prikolice za kolesa (tj. z enim ali dvema kolesoma) in njihove priključke.
Te prikolice za kolesa so namenjene prenosu tovornih bremen ali do dveh pasivnih otrok (to pomeni, da ne poganjata pedalov), ki sta zmožna sedeti brez pomoči in katerih teža ne presega 22 kg na osebo.
Največja dovoljena teža takšne prikolice za kolo, vključno s tovorom in/ali osebami, ne sme presegati 60 kg.
Ta standard se ne uporablja za priklopnike za kolesa (eno- ali dvotirna prikolica za prevoz ene ali dveh oseb, ki poganjata pedale, običajno otrok, z napravo za povezavo za kolesom) in za prikolice vrste L za profesionalno uporabo ali z enim samim kolesom (enotirna prikolica) v skladu s preglednico 1.

Type C2 is a two track cycle trailer for the transportation of children and luggage. 4.2 Sampling A single trailer shall be subjected to all of the following tests. 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

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. No two parts of a test limb shall be bent more acutely than 90°. No part of the test leg shall pass behind a vertical plane through points B. Use all available seating positions.
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. SIST EN 15918:2011+A2:2017

The drawbar load shall not be negative. If the height of the connecting device is more than 400 mm above the road surface, it shall be verified that it is possible to decelerate the bicycle and trailer combination at not less than 0,35 g according to the calculation in Annex B. 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. #

All surfaces of the cycle trailer shall be free from burrs and sharp edges. 6.4.2 Test methods All hazardous edges and protrusions shall be tested by visual and tactile inspection. 6.5 Shear and compression points for type C cycle trailers The roadway and any parts of the trailer which move or rotate relative to it when the trailer is in motion, shall not be within the access zone. Nether shall there be within the access zone, any shear or compression points between moving parts that can close to less than 12 mm, except if this motion occurs only when the trailer or a part of it is being erected, folded or adjusted (e.g. adjustment of the backrest). The edges and ends of any parts within the access zone (see 4.6) shall be rounded in accordance with 6.4, unless the clearance between the edge or end and an opposing surface is always less than 5 mm. 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.

If the barrier has holes to permit ventilation, the size of the holes shall be smaller than 4 mm. 6.7.2 Test methods Check the holes by using a probe of diameter (+0104, ) mm and a hemispherical end of 2 mm radius given in Figure 3 which shall have a weight of 100 g. Apply the force on 5 different places for 5 s each. An example of how to apply the probe is shown in Figure 4.
