The tests are designed to ensure the strength and durability of individual parts as well as of the bicycle as a whole, dema

34、.3.4.1.2 Definition of strength testsStrength tests to which accuracy requirements apply, as in 4.1.4, are those involving static, impact, or fatigue loading as specified in ISO 4210-2:2014, 4.7 to 4.13, ISO 4210-2:2014, 4.16, and ISO 4210-2:2014, 4.20.2.4.1.3 Numbers and condition of specimens for
35、the strength testsIn general, for static, impact, and fatigue tests, each test shall be conducted on a new test sample, but if only one sample is available, it is permissible to conduct all of these tests on the same sample with the sequence of testing being fatigue, static, and impact.When more tha
36、n one test is conducted on the same sample, the test sequence shall be clearly recorded in the test report or record of testing. It should be noted that if more than one test is conducted on the same sample, earlier tests can influence the results of subsequent tests. Also, if a sample fails when it
37、 has been subjected to more than one test, a direct comparison with single testing is not possible.INTERNATIONAL STANDARD ISO 4210-3:2014(E) ISO 2014 All rights reserved 1BS EN ISO 4210-3:2014ISO 4210-3:2014(E)In all strength tests, specimens shall be in the fully finished condition.4.1.4 Accuracy t

40、 against the front mudguard stays; maintain this force for 1 min.Remove the rod and determine whether or not the wheel is free to rotate and whether or not any damage to the front mudguard adversely affects wheel rotation (blocking of the wheel) and the steering.2 ISO 2014 All rights reservedBS EN I

44、r, flat-ended tool radially towards the tyre with a force of 80 N as shown in Figure 2.While the force is maintained, rotate the wheel manually in the direction of forward movement of the bicycle and determine whether or not the front mudguard is rolled up the wheel, and whether or not any damage to
45、 the front mudguard adversely affects wheel rotation (blocking of the wheel) or obstructs the steering. Contact between tyre and mudguard is allowed.4.3 Road test on a fully assembled bicycle test methodsFirst, check and adjust, if necessary, each bicycle selected for the road test to ensure that th
46、e steering and wheels rotate freely without slackness and that brakes are correctly adjusted and do not impede wheel rotation. Check and adjust wheel alignment and, if necessary, inflate tyres to the maximum inflation pressure. Check and correct, if necessary, transmission-chain adjustment, and chec
47、k any gear controls for correct and free operation.Carefully adjust the saddle and handlebar positions to suit the rider.The test shall be carried out with the permissible total weight specified by the manufacturer in ISO 4210-2:2014, Clause 5 item h). Ensure that the bicycle is ridden for at least
48、1 km.4.4 Durability test of markingRub the marking by hand for 15 s with a piece of cloth soaked in water and again for 15 s with a piece of cloth soaked in petroleum spirit.4 ISO 2014 All rights reservedBS EN ISO 4210-3:2014ISO 4210-3:2014(E)4.5 Fatigue testThe force for fatigue tests is to be appl
