Dimensions in mm Foreword This standard has been prepared by the Normenausschu Eisen und Stahl (Steel and Iron Standards Committee). It should be note

3、d that at the European level ECISSTTC 11 is currently reviewing standardized sizes for sections and bearing piles with parallel flanges. Upon publication of the relevant European Standard, DIN 1025-2 to DIN 1025-5 will be withdrawn. Amendments In comparison with the October 1963 edition, H sections

5、 I and H sections (H sections, for short), with paral- lel flanges, preferably made from DIN EN 10 025 steel. This standard does not cover: a) hot rolled I sections (I series, with a smaller ratio of flange width to web height; cf. DIN 1025-1); b) hot rolled I and H sections (IPBI series, with thinn

6、er webs and flanges; cf. DIN 1025-3); c) hot rolled I and H sections (IPBv series, with thicker webs and flanges; cf. DIN 1025-4); d) hot rolled I and H sections (IPE series, with narrower flanges; ci. DIN 1025-5). 2 Normative references This standard incorporates, by dated or undated reference, pro

Price group 5 Sales No. 0105 Page 2 DIN 1025-2 3 Designation The standard designation shall give, in the following order: a) The name of product (H section); b) the DIN number (DIN 1025); c) the material designation or number; d) the section symbol in accordance with table 1. EXAMPLE: The des

12、ignation of a hot rolled H section complying with this standard, made from steel grade S235JR (material number 1.0037) as specified in DIN EN 10 025, of the IPB series, with a height, h, of 360 mm (IPB 360) shall read: H section DIN 1025 - S235JR - IPB 360 or H section DIN 1025 - 1 .O037 - IPB 360 4

13、 Dimensions and mass 4.1 Hot rolled H sections with parallel flanges shall have the dimensions specified in table 1. 4.2 The nominal length shall be specified at the time of ordering. 4.3 The values of mass specified in table 1 have been cal- culated taking the density as 7,85 kg/dm3. Y I t b 5 Form

14、 and dimensional tolerances The dimensions of sections are subject to the tolerances specified in DIN EN 10 034. 6 Material Sections shall preferably be made from DIN EN 10 025 steel, the particular steel grade being specified at the time of order- ing.
