2、1963 edition. I-Profile mit geneigten inneren Flanschflchen; Grenzabmae und Form- toleranzen European Standard EN 10024:1995 has the status of a DIN Standard. A comma has been used as the decimal marker. National foreword This standard has been prepared by ECISSTTC 11. The responsible German body in
3、volved in its preparation was the Normenausschu Eisen und Stahl (Steel and Iron Stand- ards Committee), Technical Committee Warmgewalzte Profilerzeugnisse. It should be noted that it is not intended to specify nominal sizes of I sections. Amendments In comparison with DIN 1025-1, October 1963 editio
4、n, the following amendments have been made: a) Sizes of I sections are no longer specified. b) Some tolerances on flange thickness, web thickness, out-of-squareness, web off-centre, straightness and length have been amended. c) A limit deviation of +4% has been specified for the mass.

18、d shape 4.1 Height Any deviations of the height (h) from the nominal value shall be within the tolerance given in table 1. 4.2 Flange width Any deviations of the flange width(b) from the nominal value shall be within the tolerance given in table 1. 4.3 Web thickness Any deviations of the web thickne
19、ss (s) from the nominal value, when measured at the mid-width position of the web, shall be within the tolerance given in table 1. 4.4 Flange thickness Any deviations of the flange thickness (t) from the nominal value, when measured at a distance equal to b/4 from the mid-width position of the flang
20、e, shall be within the toler- ance given in table 1. 4.5 Out-of-squareness The out-of-squareness of the section (k + k) shall not ex- ceed the value given in table 1. 4.6 Web off-centre The mid-thickness of the web shall not deviate from the mid-width position on the flange by more than the distance
21、 (e) given in table 1. 4.7 Straightness The straightness (qXx or q,) shall comply with the require- ments given in table 1. 5 Tolerance on mass The mass of a batch or piece shall be within f 4,O % of the calculated mass (see table 1). The mass deviation is the difference between the actual mass of t
22、he batch or piece and the calculated (theoretical) mass. The theoretical mass shall be determined taking the density as 7,85 kg/dm3. 6 Tolerance on length The sections shall be cut to ordered lengths to tolerances (see table 1) of either a) f50 mm or, by agreement, b) +lo: mm.
