8 Dimensions and sectional properties The nominal sectional properties of hollow sections within the scope of this part of EN 10210 and manufactured to the dimensional tolerances of this standard, required for the purposes of structural design, shall be calculated in accordance with Annex A.
The sectional properties for a limited range of standard sizes of hot finished circular, square, rectangular and elliptical hollow sections are given in Table B.1 for circular sections, Table B.2 for square sections, Table B.3 for rectangular sections and Table B.4 for elliptical sections. These sectional properties were calculated from the formulae given in Annex A.
NOTE Not all sizes and thicknesses shown in Tables B.1, B.2, B.3 and B.4 are available from all manufacturers and the user is recommended to check availability. Other sizes and thicknesses within the scope of this standard may be available.

Formulae for the calculation of sectional properties A.1 General Tables B.1, B.2, B.3 and B.4 of this standard give nominal sectional properties for a limited range of sizes of hot finished hollow sections. The nominal sectional properties of hollow sections supplied to the requirements of this standard shall be calculated using the formulae given below. 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. This is a change from previous axis designations.

Specified outside diameter (D) (mm) Specified thickness (T) (mm) Inside diameter (d = D - 2T) (mm) These parameters, which characterize the shape of circular hollow sections, may vary within the tolerances allowed by this standard and the sectional properties still remain valid.
