39、 4210-6:2015 (E) 4 IntroductionThis International Standard has been developed in response to demand throughout the world, and the aim has been to ensure that bicycles manufactured in compliance with this International Standard will be as safe as is practically possible. The tests have been designed
40、to ensure the strength and durability of individual parts as well as of the bicycle as a whole, demanding high quality throughout and consideration of safety aspects from the design stage onwards.The scope has been limited to safety considerations and has specifically avoided standardization of comp
41、onents.If the bicycle is to be used on public roads, national regulations apply.DIN EN ISO 4210-6:2015-12 EN ISO 4210-6:2015 (E) 5 1 ScopeThis part of ISO 4210 specifies the frame and fork test methods for ISO 4210-2.2 Normative referencesThe following documents, in whole or in part, are normatively
42、 referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

44、terms and definitions given in ISO 4210-1 apply.4 Frame test methods4.1 Frame Impact test (falling mass)4.1.1 GeneralManufacturers of frames are permitted to conduct the test with a dummy fork (see Annex A) fitted in place of a front fork.Where a frame is convertible for male and female riders by th
45、e removal of a bar, test it with the bar removed.Where a suspension fork is fitted, test the assembly with the fork extended to its unloaded free length. Where a rear suspension system is incorporated in the frame, secure the suspension in a position equivalent to that which would occur with an 80 k
46、g rider seated on the bicycle. For young adult bicycles, secure the suspension in a position equivalent to that which would occur with a 40 kg rider seated on the bicycle; if the type of suspension system does not permit it to be locked, then replace the spring/damper unit by a solid link of the app
47、ropriate size and with end fittings similar to those of the spring/damper unit.4.1.2 Test methodAssemble a roller of mass less than or equal to 1 kg and with dimensions conforming to those shown in Figure 1 in the fork. The hardness of roller shall be not less than 60 HRC at impact surface. If a dum
48、my fork is used in place of a fork, the bar shall have a rounded end equivalent in shape to the roller. Hold DIN EN ISO 4210-6:2015-12 EN ISO 4210-6:2015 (E) 6 the frame-fork or frame-bar assembly vertically with clamping to a rigid fixture by the rear-axle attachment points as shown in Figure 1.Rest a striker of mass 22,5 kg on the roller in the fork dropouts or on the rounde
