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 Prüfver¬fahren für zweispurige Fahrradanhänger (das heißt mit einem oder zwei Rädern) und deren Verbin-dungseinrichtungen fest.
Diese Fahrradanhänger sind für die Beförderung von Nutzlasten oder von bis zu zwei 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 be-förderten Person(en), liegt bei 60 kg.
Diese Norm gilt nicht für Anhängerfahrräder (ein  oder zweispuriger Fahrradanhänger für die Beför-derung von ein oder zwei tretenden Personen, üblicherweise Kinder, mit einer Vorrichtung zur An-bringung 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.

Overview

EN 15918:2011+A2:2017 is a European Standard published by CEN that defines safety requirements and test methods for two-track cycle trailers (bicycle trailers with one or two wheels) and their connecting devices. It applies to trailers intended to carry cargo or up to two passive child passengers (each capable of sitting unaided and ≤ 22 kg). The standard limits the maximum permitted total weight (trailer plus cargo/passengers) to 60 kg and excludes trailer cycles for pedalling passengers and certain single‑wheel or professional trailers.

Key Topics and Technical Requirements

The standard combines design rules and measurable test methods to assess safety and durability. Key topics include:

• Materials and flammability: requirements for chemical migration and flame behaviour for passenger compartments.
• Construction and dimensions: general construction, headroom and access zones for passenger safety.
• Drawbar and connecting device: load, height, pitch pivot behaviour and strength tests for the hitching system.
• Deflection, folding and frame integrity: folding mechanisms, frame/chassis strength and rigidity tests.
• Parking brake and stability: parking brake performance and trailer stability requirements and tests (including dynamic and static sequences).
• Restraint systems and passenger protection: strength of harness/restraint systems, entrapment, shear/compression points, small parts and front protection for type C trailers.
• Lighting, reflectors and conspicuity: provisions for visibility aids.
• Test methods and reporting: defined order of tests, test bodies (Annex A), deceleration calculations (Annex B), and required test report contents.
• Marking and instructions: mandatory markings, user instructions and durability of markings.

Applications and Who Uses It

EN 15918:2011+A2:2017 is used by:

• Manufacturers and designers of bicycle trailers to ensure compliance with EU safety expectations and to design safe connecting devices, brakes and passenger compartments.
• Testing laboratories and certification bodies that perform standardised mechanical, dynamic and chemical tests (per EN ISO/IEC 17025 competence expectations).
• Regulators and national standards bodies adopting the CEN text as national standards.
• Retailers, fleet operators and safety engineers assessing product safety for consumers and urban mobility systems.
  Practical benefits: reduces injury risk, defines reproducible test protocols, and supports clear consumer instructions and product markings.

Related Standards

Normative references in EN 15918 include:

• EN 71-1 / EN 71-3 (relevant toy safety migration/physical tests where applicable)
• EN 1888 (child conveyances)
• EN ISO/IEC 17025 (testing laboratory competence)

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

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
