29、rnational 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 to ensure the strength and durability of
30、 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 components.If the bicycle is to be used on
31、public roads, national regulations apply.4DIN EN ISO 4210-5:2015-01 EN ISO 4210-5:2014 (E) 1 ScopeThis part of ISO 4210 specifies the steering test methods for ISO 4210-2.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispens

Remove the handlebar from the freezer an
35、d allow the temperature of the handlebar to reach 5 C, and then apply a force of 70 N to the grip or plug in the loosening direction as shown in Figure 1. Maintain the force until the temperature of the handlebar has reached +5 C. It shall be permitted to create a hole in the plug to allow for the t
36、esting fixture to be fitted so long as the hole does not affect the seat of the plug in the handlebar and the fixture does not contact the handlebar during the test.5DIN EN ISO 4210-5:2015-01EN ISO 4210-5:2014 (E)Key1 handlebar grip2 handlebar3 drawing attachment4 hooking ring5 clearanceNOTE The hoo
