1、UDC 669.14.018.29-423.1 :621.713.1 DEUTSCHE NORM March 1994 I I Structural steel I and H sections English version of DIN EN 10034 Tolerances on shape and dimensions DIN - EN 10034 I- und H-Profile aus Baustahl; Grenzabmae und Formtoleranzen This standard, together with the March 1994 editions of DIN
2、 1025 Parts 2 to 5, supersedes the October 1963 editions of DIN 1025 Parts 2, 3 and 4 and the March 1965 edition of DIN 1025 Part 5. European Standard EN 10034:1993 has the status of a DIN Standard. A comma is used as the decimal marker. National foreword This standard has been prepared by ECISS/TC
3、11. The responsible German body involved in its preparation was the Normenausschu Eisen und Stahl (Steel and Iron Standards Committee), Technical Committee Warmgewalzte Profilerzeugnisse. The present standard specifies dimensional and geometrical tolerances for I and H sections and bearing piles, wh
4、ich had been given previously in DIN 1025 Parts 2 to 5. The values no longer apply for specific section shapes. The scope of the present standard covers many more sizes than the DIN Standards did, and includes, for example, a flange width of 420 mm and a flange thickness of 75 mm. Negoti- ations are
5、 continuing within ECISS/TC 11 for harmonizing the sizes of I and H sections. In specifying tolerances on the cross-sectional dimensions, ECISS/TC 11 endeavoured to specify values which, where lower limit deviations are chosen, do not lead to an automatic reduction of static parameters, which would
6、necessitate the use of higher factors of safety when designing the particular steel structure. These efforts resulted in an asymmetrical distribution of limit deviations, and in a reduction of the tolerance on nominal mass for single sections to * 4 %.

These requirements do not apply to I and H sections rolled
23、from stainless steel, nor to taper flange sections. NOTE: Until a European Standard covering the dimensions of I and H beams is published, EURONORM 19 and EURONORM 53, or corres- ponding national standards, may be used. 2 Normative references This European Standard incorporates, by dated or undated

The mas
32、s deviation is the difference between the actual mass of the batch or item and the calculated mass. The calculated mass shall be determined using a density of 735 kg/dm3. 6 Tolerance on length The sections shall be cut to ordered lengths, within tol- erances of: a) I50 mm, or b) tr 100 mm, where min
33、imum lengths are ordered. L represents the longest useable length of the section, assuming that the ends of the section have been cut square (see figure 1). I- Figure 1: Measurement of length L of I and H sections Annex A (informative) Straightness measurement Straightness measurement requires the u
34、se of a 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 plane only are measured. Measurement for qxr shall be carried out as follows: The section is laid in the H position on a fla
35、t surface, and the string is taken from the outside of the centre of the flange width between the two ends of the unconstrained section. Measurement for qyy shall be carried out as follows: The section is laid in the I position on a flat surface, and the string is taken along the flange tip between the two ends of the unconstrained section.
