25、. 4 Rolling tolerances for structural steel I and H sections 4.1 Section height (h) The deviation from nominal on section height measured at the centre line of web thickness shall be within the tolerance given inTable 1. 4.2 Flange width (b) The deviation from nominal on flange width shall be within
26、 the tolerance given inTable 1. 4.3 Web thickness (s) The deviation from nominal on web thickness measured at the mid-point of dimension h shall be within the tolerance given inTable 1. 4.4 Flange thickness (t) The deviation from nominal on flange thickness measured at the quarter flange width point
27、 shall be within the tolerance given inTable 1. 4.5 Out-of-squareness (k + k) The out-of-squareness of the section shall not exceed the maximum given inTable2. 4.6 Web off-centre (e) The mid-thickness of the web shall not deviate from the mid-width position on the flange by more than the distance (e
28、) given inTable2. 4.7 Straightness (q xxor q yy ) The straightness shall comply with the requirements given inTable3. 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 pie
29、ce and the calculated mass. The calculated mass shall be determined using a density of 7,85 kg/dm 3 . 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.

34、ent Straightness measurement requires a reference straight edge from which deviations in section straightness are measured. A taut string line is an acceptable straight edge provided that deviations in the horizontal plan only are measured. Measurement is carried out as follows: for q xx : The beam
35、is laid in the H position on a flat surface and the string is taken along the outside of the centre of the flange width between the two ends of the unconstrained section. for q yy : The beam is laid in the I position on a flat surface and the string is taken along the flange tip between the two ends
