28、sible. 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 stage onwards.The scope has been limited to safety considerations and has specifi
29、cally avoided standardization of components.If the bicycle is to be used on public roads, national regulations apply.

33、ith the suspension system either free to operate or locked. If it is locked, the pillar shall be at its maximum length.4.2 Saddle/seat-post Security testWith the seat-post correctly assembled to the bicycle frame at minimum insertion depth of the seat-post (as specified in ISO 4210-2:2014, 4.16.2),
34、and the clamps tightened to the torque recommended by the bicycle manufacturer, apply a force of F1vertically downwards at a point 25 mm from either the front or rear of the saddle, whichever produces the greater torque on the saddle clamp. The saddle shall be positioned in the seat-post clamp assem
35、bly as defined by the saddle manufacturers rail markings or instructions. Maintain this force for 1 min. Remove this force and apply a lateral force of F2horizontally at a point 25 mm from either the front or rear of the saddle and maintain this force for 1 min, whichever produces the greater torque
36、 on the clamp (see Figure 1). The forces are given in Table 1. The fixture shall be such that it does not damage the surface of the saddle.INTERNATIONAL STANDARD ISO 4210-9:2014(E) ISO 2014 All rights reserved 1BS EN ISO 4210-9:2014ISO 4210-9:2014(E)Table 1 Forces on saddleForces in newtonsBicycle t

Tighten the clamps to the torque recommended by the bicycle manufacturer, a
39、nd apply forces of 400 N in turn under the rear and nose of the saddle cover, as shown in Figure 2, ensuring that the force is not applied to any part of the chassis of the saddle. The load application point is on the longitudinal plane of the saddle at 25 mm from the back (front) of the saddle. If
40、the saddle design is such that it cannot accept a centreline 2 ISO 2014 All rights reservedBS EN ISO 4210-9:2014ISO 4210-9:2014(E)load application, the load shall be symmetrically applied at two points of the saddle.

For this reason, a saddle shall be tested in combination with a seat-post as recommended by the saddle manufacturer.4.4.2 Test methodInsert the seat-post to its minimum insertion depth (as specified in ISO 4210-2:2014, 4.
43、16.2) in a rigid mount representative of that on the bicycle and with its axis at 73 to the horizontal. The saddle shall be positioned in the seat-post clamp assembly in a maximum rearward direction as defined by the saddle manufacturers rail markings or instructions. Adjust the saddle to have its u
44、pper surface in a horizontal plane and tighten the clamp to the torque recommended by the bicycle manufacturer. Apply a repeated, vertically-downward force of 1 000 N for 200 000 cycles, in the position shown in Figure 4, by means of a pad 300 mm long 80 mm diameter to prevent localized damage of th
45、e saddle cover. The maximum test frequency shall be maintained as specified in ISO 4210-3:2014, 4.5.Key1 rigid mount2 minimum insertion-depth mark3 pad (length = 300 mm, diameter = 80 mm)Figure 4 Saddle and seat-post clamp fatigue test4 ISO 2014 All rights reservedBS EN ISO 4210-9:2014ISO 4210-9:201

47、e minimum insertion depth (as specified in ISO 4210-2:2014, 4.16.2) in a suitable fixture with a representative seat collar and clamped to the manufacturers recommended torque. The seat-post shall be fixed at an angle of 73 from horizontal, as shown in Figure 5.Secure an extension-bar to the saddle
48、attachment point by the appropriate attachment fitting such that the bar extends rearwards and downwards at an angle of 10 below the horizontal to permit the application of a vertical test force at a distance of 70 mm from the centre of the saddle clamp where the centreline of the clamp intersects t
49、he axis of the bar, as shown in Figure 5.Apply a repeated, vertically downward, dynamic force of F3to the point described above and shown in Figure 5 for 100 000 cycles. The forces are given in Table 2.
