IntroductionThis International Standard has been developed in respo
29、nse 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 individual parts as well as of the bicycle as
30、 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 public roads, national regulations apply.4DIN

38、 The masses are given in Table 1.Drive the shaft at a speed not exceeding 100 min1for a total of 100 000 revolutions. If the pedals are provided with two tread surfaces, they shall be turned through 180 after 50 000 revolutions.Table 1 Masses on pedalBicycle typeCity and trekking bicyclesYoung adult

41、014 (E) 4.4.1.2 Single-speed systemWith the non-drive side crank in the forward position, apply a force, F1, increasing gradually to 1 500 N vertically downwards to the centre of the non-drive side pedal. Maintain this force for 1 min.Should the system yield or the drive-sprockets tighten, such that
42、 the crank rotates while under load to a position more than 30 below the horizontal, remove the test force, return the crank to the horizontal position or some appropriate position above the horizontal to take account of yield or movement, and repeat the test.On completion of the test on the non-dri
43、ve side crank, repeat the test with the drive side crank in the forward position and with the force applied to the drive side pedal.4.4.1.3 Multi-speed systema) Conduct the tests described in 4.4.1.2 with the transmission correctly adjusted in its highest gear.b) Conduct the tests generally as descr
44、ibed in 4.4.1.2 with the transmission correctly adjusted in its lowest gear but, where appropriate, with the maximum force, F1, adjusted to suit the particular gear ratio. Thus:The maximum force, F1, shall be a function of the lowest gear ratio, Nc/Ns,whereF1is the force applied to the pedal, expres
45、sed in newton (N);Ncis the number of teeth on the smallest chain wheel (front);Nsis the number of teeth on the largest sprocket (rear).Where the ratio Nc/Nshas a value equal to or greater than 1, the force, F1, shall be 1 500 N; but where the ratio Nc/Nshas a value less than 1, the force, F1, shall
46、be reduced in proportion to the lowest gear ratio. Thus:F1is 1 500 Nc/Ns.4.4.2 Test method for drive system with beltThe sample in its fully finished condition (with teeth, if any) shall be submitted to a water spray conditioning equivalent to IPX4 specified in IEC 60529:2001, 14.2.4 during 10 min.
47、Application of the loading shall be done within 20 min after conditioning.a) If the drive system is a single-speed system, conduct the tests as described in 4.4.1.2.b) If the drive system is a multi-speed system, conduct the tests as described in 4.4.1.3.4.5 Drive belt Tensile strength testSet up a
48、fixture with two drive pulleys that are similar or identical as shown in Figure 5. At least one pulley should be free to rotate. Increase the tensile load gradually until the tension load of the belt reaches 4 000 N.NOTE 4 000 N is the tension load within the belt and requires a load F of 8 000 N to
49、 achieve this tension load.9DIN EN ISO 4210-8:2015-01EN ISO 4210-8:2014 (E)Figure 5 Drive belt Tensile strength test4.6 Crank assembly Fatigue test4.6.1 GeneralTwo types of fatigue test are specified for mountain bicycles: the first test with the cranks positioned at 45 to the horizontal to simulate the forces due to pedalling, and the second test with the cranks positioned at 30 to t
