32、ight spikes, not including spurs. 4.1.3 Each crampon shall have at least six downward spikes, which: a) shall be at least 20 mm long (see Figure 2) and not necessarily all the same length; b) when walking normally on flat and smooth ice, shall contact the surface of the ice, but not necessarily at t

33、he same time; and c) shall be shaped such that when loaded with one persons weight whilst walking on smooth ice, the downward spikes will “bite“ into the ice such as to prevent slipping. Dimensions in millimetres Figure 2 Length of spikes 4.1.4 All edges with which the users hands can come into cont

34、act shall be free from burrs. 4.1.5 If the crampon has a clip-on binding it shall be fitted with a retaining system. 4.2 Prevention against slippage When tested according to 5.4.2, the crampons shall not slip on the ice more than 10 mm in each direction. 4.3 Strength 4.3.1 Hardness Each part of the

35、crampon, which contains a spike or spikes, shall have a hardness of at least 70 HRB. Testing according to 5.4.1.3. 4.3.2 Bending and breaking strength of spikes When tested according to 5.4.3, the maximum deformation under load and the permanent deformation after removing the load, measured at the p

36、oint of application, shall not be more than shown in Table 1. The breaking strength shall be at least as shown in Table 1. Spurs shall be tested with a load applied in each intended direction.

Permanent deformation is acceptable. If the crampon is directly attached or

39、integrated into a boot the transverse strength requirements are not applicable. 4.3.4 Strength of binding parts other than bails When tested according to 5.4.5, each part shall not break. 4.3.5 Strength of attachment rings and eyes and of the appropriate part of the binding When tested according to

40、5.4.7, attachment rings and eyes and the appropriate part of the binding shall not break.
