This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2006, and conflicting national standards shall be withdrawn at the latest by August 2006. Accordi

EN 14872:2006 (E) 4 Introduction This European Standard has been developed in response to demand throughout Europe, and the aim has been to ensure that luggage carr

20、iers manufactured in compliance with it will be as safe as is practically possible. The tests have been designed to ensure the strength and durability of the luggage carrier, demanding high quality throughout and consideration of safety aspects from the design stage onwards. The scope has been limit

21、ed to safety considerations, and has specifically avoided standardisation of components. EN 14872:2006 (E) 5 1 Scope This European Standard specifies safety and performance requirements for the design and testing of luggage carriers intended for permanent mounting above or adjacent to the wheels of

22、cycles and lays down guide lines for instructions on the use and care of such luggage carriers. This European Standard does not apply to removable luggage (for example handlebar bags or baskets that are not permanently attached). 2 Normative references The following referenced documents are indispen

23、sable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 14344, Child use and care articles Child seats for cycles Safety requirements and te

24、st methods 3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1 cycle vehicle that has at least two wheels and is propelled solely or mainly by the muscular energy of the person on that vehicle, in particular by means of pedals (from EN 1

25、4764) 3.2 luggage carrier device, including containers such as baskets, that is mounted and permanently attached above and/or adjacent to the rear wheel(s) (in the case of a rear luggage carrier) or front wheel(s) (in the case of a front luggage carrier) of a cycle and that is exclusively designed f

26、or carrying luggage or children in child-seats 3.3 luggage-carrier platform flat part of the luggage carrier upon which loads may be placed or fixed, or the flat top rail from which panniers may be hung or the bottom part of a container (for example a basket). If the luggage carrier is equipped with

27、 more than one such area, only the uppermost is considered 3.4 luggage-carrier platform length, L maximum overall length of the luggage-carrier platform (flat part) 3.5 visible crack crack which results from a test where that crack is visible to the naked eye (from EN 14764) 3.6 fracture separation

28、into two or more parts (from EN 14764) EN 14872:2006 (E) 6 4 Classification The manufacturer shall classify the carrier with the maximum load capacity for which it is intended, taking into consideration any restrictions laid down in Table 1. If the carrier is intended to carry a child seat, designed

29、 to clamp onto the platform of a normal rear luggage carrier, classified for 9 kg to15 kg according to EN 14344, the maximum load capacity of the luggage carrier shall be at least 18 kg. If the carrier is intended to carry a child seat, designed to clamp onto the platform of a normal rear luggage ca

30、rrier, classified for 9 kg to 22 kg according to EN 14344, the maximum load capacity of the luggage carrier shall be at least 25 kg. In Table 1, the maximum limit (if any) for the load capacity is indicated for each type of luggage carrier that falls within the scope of this European Standard. The a

31、pplicable requirements and test methods differ according to the type and load capacity. The following terminology is used in the table: normal rear carrier: rear carrier supported by fixings to the bicycle frame close to the rear wheel axle; frame-mounted beam carrier: rear carrier that is structura

32、lly a cantilever, fixed to the bicycle frame in front and/or above the rear wheel. It may also be fixed to the seatpost, in addition to the frame, but receives no support from the bicycle frame near to the axle of the rear wheel; seatpost-mounted beam carrier: rear carrier that is structurally a can

33、tilever, fixed to the seatpost of the bicycle without additional fixings to the frame; above wheel front carrier: front carrier with a platform upon which loads can be placed above the front wheel; low-load front carrier: front carrier that is exclusively designed for carrying a pair of panniers, wh

34、ere the “platform” is a pair of rails (from which the panniers hang) one each side of the wheel and not more than 200 mm above the lower points of attachment of the carrier near to the axle of the front wheel; front-mounted container: container such as a basket, that is mounted and permanently attac

35、hed above the front wheel of a bicycle and that is exclusively designed for carrying luggage.

37、t is permissible to conduct all of the tests on the same sample with the sequence of testing in the order: fatigue tests, static tests. In the strength tests all components shall be in the fully-finished condition. The test frequency shall be stated in all fatigue test reports. 5.2 Tolerances Unless

38、 otherwise stated the following tolerances shall be used: All forces shall have an accuracy of 5 %. All masses shall have an accuracy of 1 %. All dimensions shall have an accuracy of 1,0 mm. All time measurements shall have an accuracy of 1 s. All angles shall have an accuracy of 1. All frequencies

39、and amplitudes shall have an accuracy of 5 %. 5.3 Sharp edges Exposed edges that could come into contact with the riders or a transported persons hands, legs etc., during normal riding or normal handling and normal maintenance shall be neither sharp nor designed such that injuries can arise when the

40、 bicycle is used correctly. Spring ends shall be rounded or fitted with protective caps. 5.4 Security of safety-related fasteners 5.4.1 Security of screws Any screws used in the assembly of the luggage carrier or screws used to attach the luggage carrier shall be provided with suitable locking devic

41、es, for example, lock-washers, lock-nuts, or stiff nuts. 5.4.2 Minimum failure torque The minimum failure torque of screws for the fastening of the luggage carrier to the cycle shall be at least 50 % greater than the manufacturers recommended tightening torque. 5.5 Crack detection methods Standardis

42、ed methods may be used to emphasise the presence of cracks where visible cracks are specified as criteria of failure in tests specified in this European Standard. NOTE For example, suitable dye-penetrant methods are specified in ISO 3452. EN 14872:2006 (E) 8 5.6 Dimensions The dimensions of luggage

43、carriers are not specified, except as follows: Normal rear luggage carriers of load classes 18 and 25, to which a child-seat could be attached (see Clause 4), shall have a luggage-carrier platform width of between 120 mm and 175 mm. 5.7 Protrusions 5.7.1 Requirement 5.7.1.1 Exposed protrusions Any r

44、igid exposed protrusion longer than 8 mm (see L in Figure 1 ) after assembly shall terminate in a radius, R (see Figure 1 ), of not less than 6,3 mm. Such protrusions shall have a major end dimension, A, not less than 12,7 mm and a minor dimension, B, not less than 3,2 mm. Dimension in millimetres K

47、igure 2. Manoeuvre the test cylinder in all possible attitudes towards any rigid protrusion on the luggage carrier. If the central 75 mm long section of the cylinder contacts the protrusion, that protrusion shall be considered to be an exposed protrusion and it shall comply with 5.7.1.1. Examples of

48、 protrusions that need and do not need to comply with the requirements are shown in Figure 3. Key 1 test cylinder 2 protrusion shall comply 3 protrusion needs not to comply Figure 3 Examples of protrusions EN 14872:2006 (E) 10 5.8 Assembly When attached to a fixture resembling a bicycle (or attached

49、 to a bicycle) and if necessary assembled in accordance with the manufacturers instructions, the luggage carrier parts shall be firmly joined and fixed using the fixing devices provided or specified by the manufacturer. Parts of luggage carriers shall be assembled to one another and attached to the bicycle using fixings of nominal diameter not less than 5 mm. 5.9 Rear luggage carriers - Provision for lighting The rear aspect of any rear luggage carrier not equipped with an int
