Sectional properties for a limited range of standard sizes.20
Elliptical: Outside dimensions up to 500 mm x 250 mm The formulae for calculating sectional properties of sections manufactured to the dimensional tolerances of this standard, to be used for the purposes of structural design, are given in Annex A.
Dimensions and sectional properties for a limited range of sizes are given in Annex B. Technical delivery conditions are specified in EN 10210-1. NOTE The designation of the sections' major axis (yy) and its minor axis (zz) align with the axis designation used for structural design in the structural Eurocodes.

a For elliptical hollow sections of sizes H < 250 mm the permitted tolerance is twice the value given in this table. b
The positive deviation is limited by the tolerance on mass. c For seamless sections thicknesses of less than 10 % but not less than 12,5 % of the nominal thickness may occur in smooth transition areas over not more than 25 % of the circumference. d Where the diameter to thickness ratio exceeds 100, the tolerance on out-of-roundness shall be agreed. e The tolerance on convexity and concavity is independent of the tolerance on outside dimensions. f The sides need not be tangential to the corner arcs. g The positive tolerance on the mass of seamless hollow sections is 8 %.
