BS EN 10210-2:2006 – Hot finished structural hollow sections of non-alloy and fine grain steels — Part 2: Tolerances, dimensions and sectional properties

1 Scope
This part of EN 1 021 0 specifies tolerances for hot finished circular, square, rectangular and elliptical structural hollow sections, manufactured in wall thicknesses up to 1 20 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 of sizes are given in Annex B.
Technical delivery conditions are specified in EN 1 021 0-1 .
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.
2 Normative references
The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 1 021 0-1 :2006 apply.
4 Symbols
For the purposes of this European Standard, the symbols defined in Table 1 apply.
5.2 Options
One option is specified in this part of EN 1 021 0. In the event that the purchaser does not indicate a wish to implement this option at the time of enquiry and order, the manufacturer shall supply in accordance with the basic specification.
Option 2.1 the tolerance on approximate length shall be 1500 + mm (see Table 3).
6 Tolerances
6.1 Tolerances shall not exceed the values given in Table 2 for shape, straightness and mass, Table 3 for manufacturer’s delivered length and Table 4 for the height of the internal and external weld bead of submerged arc welded hollow sections.
6.2 The internal corners of square and rectangular hollow sections shall be rounded.
NOTE The internal corner profile is not specified.
