3、as been prepared by ECISS/TC 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 specifications made in the present standard had previously been covered separat
4、ely, in DIN 1028 and DIN 1029. The form of this standard differs from that commonly used in Germany. The requirements for both nominal size and the relevant tolerances had been split up into the two DIN Standards, one covering equal and the other, unequal angles, but here, only the latter are specif
5、ied in this one product standard, although they apply to both products. Specifications regarding the nominal size ranges for equal and unequal angles are currently in preparation, and will be published in Part 1 of this European Standard (cf. clause 1). The DIN Standards corresponding to the Europea
6、n Standard and EURONORMs referred to in clause 2 of the EN are as follows: EN Standard DIN Standard EN 10079 DIN EN 10079 EURONORM 56 DIN 1028 EURONORM 57 DIN 1029 Standards referred to (and not included in Normative references) DIN EN 10079 Definition of steel products DIN 1028 Hot rolled equal ang

20、mass of hot rolled structural steel equal and unequal leg angles. The sizes of these angles are given in EN 10056-1. These tolerances do not apply to stainless steel equal and unequal leg angles. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions fr

For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amen
22、dment or revision. For undated references, the latest edition of the publication referred to applies.

24、s gjven in table 1. Leg length (a or b) For unequal leg angles, the longer leg length, a, shall be used. 4.2 Section thickness (t) The nominal section thickness shall be within the toler- ances given in table 1. 4.3 Out-of-squareness (k) The out-of-squareness of the section shall not exceed the valu
25、es specified in table 1. For unequal leg angles, the longer leg length, a, shall be used. 4.4 Deviation from straightness (4) The deviation from straightness shall not exceed the values specified in table 1. For unequal leg angles, the longer leg length, a, shall be used. 5 Tolerance on mass The dev
26、iation from the nominal mass of any angle shall not exceed C6% for thicknesses, t, not exceeding 4 mm, or f 4 % for thicknesses, t, over 4 mm. The deviation from the nominal mass is the difference between the actual mass of the angle and the calculated mass. The calculated mass shall be determined u

29、surement Straightness measurement requires the use 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 shall be carried out as follows: The angle is placed on one leg on a flat surface, and the string is taken from the flat surface to the toe of the other (unconstrained) leg. The width of the gap between the string and the unconstrained leg shall be measured.
