These requirements do not apply to channels produced from stainless steel. 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 3 Definitions For the purpose of this Standard the definitions given in EN apply. 4 Tolerances on dimensions and shape 4.1 Section height (h) The deviation from nominal on section height (h) shall be within the tolerance given in Table 1 for tapered flange channels and in Table 2 for parallel flange channels. Height is measured over the web. 4.2 Flange width (b) The deviation from nominal on flange width (b) shall be within the tolerance given in Table 1 for tapered flange channels and in Table 2 for parallel flange channels. 4.3 Web thickness (s) The deviation from nominal on web thickness (s) when measured at the midheight position of the web, shall be within the tolerance given in table 1 for tapered flange channels and in table 2 for parallel flange channels. 4.4 Flange thickness (t) The deviation from nominal on flange thickness (t), when measured at a distance of b/2 from the toe of the flange, shall be within the tolerance given in table 1 for tapered flange channels and in table 2 for parallel flange channels. 4.5 Heel radius (r 3 ) The radius of the heel radius (r 3 ) shall not exceed 0,3t where t is the flange thickness. 4.6 Out of squareness (k + k 1 ) and web bow (f) The out of squareness of the section (k + k 1 ) shall not exceed the maximum given in table 1 for tapered flange channels and in Table 2 for parallel flange channels The web flatness (f) shall not exceed the values given in Table 1 for tapered flange channels and in Table 2 for parallel flange channels.
