5 General rules

5.1 The connections and assemblies of all parts of the pump shall be firm, without looseness, gaps, deformation or the like. The cylinder and cylinder cap, and the cylinder and base, shall be connected and fixed by thread or by welding, bonding, riveting, pinning, press-fitting or similar methods. The handle of a floor pump or the foot pedal of a foot pump may be connected to the piston rod by thread. Where a threaded connection is used for fixing, anti-loosening measures shall be provided.

5.2 The parts of the pump that may come into contact with the human body shall be free from sharp edges and burrs.

5.3 There shall be no air leakage at the connections between the body and the air hose, between the air hose and the pump head or valve adapter, and between the pump head or valve adapter and the matching bicycle tyre valve.

5.4 For hand pumps with a detachable air hose, the air hose stored in the body fitted with an anti-drop device shall not fall out under riding vibration.

5.5 Pumps with a pressure gauge shall show no air leakage or the like when pressure is applied up to the maximum indicated value of the pressure gauge.

5.6 Pumps with an air reservoir shall be fitted with a safety valve or pressure regulating valve capable of controlling the pressure of the air reservoir. After it stops operating, the safety valve or pressure regulating valve shall be able to return to its initial state.

5.7 For floor pumps with a synthetic resin handle and a metal piston rod, the upper end of the metal piston rod shall be firmly covered with a metal pad of area greater than 3 cm2 or with a synthetic resin cap with a top thickness greater than 2 mm.

5.8 For floor pumps with a metal or wooden handle, the protruding part above the handle shall not be higher than the top of the piston rod by 1 mm.

5.9 When a floor pump is in its maximum compressed state, the minimum distance h between the underside of the handle and the upper end of the cylinder shall be greater than 30 mm, as shown in Figure 9 (a) metal pump; b) synthetic resin pump).

5.10 The ground-contact parts and foot pedal of foot pumps shall have an anti-slip structure, and a stroke-limiting device for the piston rod shall be fitted.
