The tests have been designed 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 sta

34、ular to the axle at a suitable point along the rim (see Figure 1 and Figure 2) (i.e. full indicator reading) of a fully assembled and adjusted wheel during one complete revolution about the axle without axial movement. Both sides of the rim shall be measured and the maximum value shall be taken as r

35、esult.For city and trekking, mountain, and young adult bicycles, the measurement of both axial run-out (lateral) and radial run-out (concentricity) shall be done with a tyre fitted and inflated to the maximum inflation pressure, but for rims where concentricity cannot be measured with the tyre fitte

36、d, it is permissible to make measurements with the tyre removed.For racing bicycles, the measurement of both axial run-out (lateral) and radial run-out (concentricity) shall be measured at the same time as shown in Figure 2 and a tyre is not required to be fitted.5DIN EN ISO 4210-7:2015-01EN ISO 421

Apply a pre-load of 5 N on the rim at one spoke perpendicular to the plane of the wheel as shown in Figure 3. Record the zero position o

40、f the rim at the point of load application as shown. Then apply a static force of F given in Table 1 for a duration of 1 min. Reduce the load to 5 N and allow a 1 min settling time. After this settling time and with the 5 N load still applied, re-measure the position of the rim.The wheel shall be fi
