I
28、n particular the different approval criteria needed for the different types of ISO documents should be noted.

The tests have been designed to ensure the strength and durability of individual parts as well as of the bicycle as a whole, de
36、manding 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 public roads, national regulations apply.

Remove the handlebar from t
41、he freezer and 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 al
42、low for the testing 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.INTERNATIONAL STANDARD ISO 4210-5:2014(E) ISO 2014 All rights reserved 1BS EN ISO 4210-5:2014ISO 4210-5:2014(E)Key1 handle
