scope:

This part of prEN 10210 specifies tolerances for hot finished circular, square, rectangular and elliptical structural hollow sections, manufactured in wall thicknesses up to 120 mm, in the following size ranges: Circular: Outside diameters up to 2 500 mm Square: Outside dimensions up to 800 mm x 800 mm Rectangular: Outside dimensions up to 750 mm x 500 mm 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 covering the more common sizes are given in Annex B. The general conditions are specified in prEN 10210-1 (product characteristics, test methods and performance criteria that apply under the Construction Products Regulations) and the technical delivery conditions in prEN 10210-2.
