EN 10034-1993 pdf download.Structural steel I and H sections and dimension olerances on shape .
This EN 10034 specifies tolerances on
shape dimensions and mass of structural steel I and
H sections. These requirements do not apply to I and
H sections rolled from stainless steel. These
requirements do not apply to taper flange sections.
NOTE Until a European Standard for dimensions of I and H beams is published Euronorm 19 and Euronorm 53 or corresponding national standards may be used.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. EN 10079. Definition of steel products. Euronorm 19:1957, IPE beams, parallel flanged beams.
Euronorm 53:1962, Wide flange beanis with parallel flanges.
3 Definitions
For the purpose of this European Standard, the
definitions in EN 10079 apply.
4 Rolling tolerances for structural
steel I and H sections
4.1 Seetion height (h)
The deviation from nominal on section height measured at the centre line of web thickness shall be within the tolerance given in Table 1.
4.2 Flange width (b)
The deviation from nominal on flange width shall be within the tolerance given in Table 1.
The deviation from nominal on web thickness measured at the mid-point of dimension h shall be within the tolerance given in Table 1.
4.4 Flange thickness (1)
The deviation from nominal on flange thickness measured at the quarter flange width point shall be within the tolerance given in Table 1.
4.5 Out-of-squareness (k + k’)
The out-of-squareness of the section shall not exceed the maximum given in Table 2.
4.6 Web off-centre (c)
The mid-thickness of the web shall not deviate from the mid-width position on the flange by more than the distance (e) given in Table 2.
4.7 Straightness (q or qyy)
The straightness shall coniply with the
requirements given in Table 3.
5 Tolerance on mass
The deviation from the nominal mass of a batch or a piece shall not exceed ± 4.0 %.
The mass deviation is the difference between the actual mass of the batch or piece and the calculated mass.
The calculated mass shall be determined using a density of 7.85 kg/dm3.
6 Tolerance on length
The sections shall be cut to ordered lengths to tolerances of:
a) ± 50 mm; or
b) + 100 mm where minimum lengths are requested.
L represents the longest useable length of the section assuming that the ends of the section have ben cut square (see Figure 1).EN 10034-1993 pdf download.
