29、 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 a whole, demanding high quality throughout, and consideration of safety aspects from the design stage onwards.The scope has been limited to safety
30、considerations and has specifically avoided standardization of components.If the bicycle is to be used on public roads, national regulations apply.4DIN EN ISO 4210-9:2015-01 EN ISO 4210-9:2014 (E) 1 ScopeThis part of ISO 4210 specifies saddle and seat-post test methods for ISO 4210-2.2 Normative ref

If it is locked, the pillar shall
34、 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), and the clamps tightened to the torque recommended by the bicycle manufacturer, apply a force
35、 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 assembly as defined by the saddle manufacturers rail markings or instructions. Maintain this force
36、 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 on the clamp (see Figure 1). The forces are given in Table 1. The fixture shall be such that
37、 it does not damage the surface of the saddle.5DIN EN ISO 4210-9:2015-01EN ISO 4210-9:2014 (E)Table 1 Forces on saddleForces in newtonsBicycle typeCity and trekking bicyclesYoung adult bicycles Mountain bicycles Racing bicyclesVertical force, F1650 650 650 650Horizontal force, F2250 250 250 250Dimen

Tighten the clamps to the torque recommended by the bicycle manufacturer, and 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 th
40、e 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 the saddle design is such that it cannot accept a centreline 6DIN EN ISO 4210-9:2015-01 EN ISO 4210-9:2014 (E) load application, the load shall be symmetric
41、ally 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.
43、4.2 Test methodInsert the seat-post to its minimum insertion depth (as specified in ISO 4210-2:2014, 4.16.2) 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 directio

Adjust the saddle to have its upper 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 pos
45、ition shown in Figure 4, by means of a pad 300 mm long 80 mm diameter to prevent localized damage of the saddle cover.

The seat-post shall be fixed at an angl
48、e of 73 from horizontal, as shown in Figure 5.Secure an extension-bar to the saddle 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 m
49、m from the centre of the saddle clamp where the centreline of the clamp intersects the 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. The maximum test frequency shall be maintained as specified in ISO 4210-3:2014, 4.5.Table 2 Forces
