3 Required characteristics
3.1 (‘ontlguration — Dimensions — Tolerances
Sec Figure 1 and Table I and Table 2.
Dimensions and tolernnerm. in millimetres. apply after ebromate treatment but bemore. primer.
3.2 Surface rough ncs
External surfaces: K4 1.6 1am
Internal surfaces: k = 3,2 pm
The values apply before chromate treatment.
3.3 Loads
See Table 3.
3.4 Buckling strength
See Figure 2.
3.5 Masses
The maximum mass, in grammes. is determined by the following formula:
whcrr:
M is (he maximum mass of the rod body, in grammes:
M, as the maiia o(a cylindrical tubc of length L. duimcier I) and thickness a in grammes; see EN 2257:
k is the coeflicwnt of the increase in mass specific to each rod body, in grammes: see Table I.
