Foreword
This European Standard has been prepared by Technical Committee ECISS/TC 11 “Structural steel sections”,the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, and conflicting national standards withdrawn, by February 1999 at the latest.
The discussions within ECISS/TC 11 were based on EURONORMs 56 and 57 and ISO 657-1 and ISO 657-2.According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Fin-land, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain,Sweden, Switzerland and the United Kingdom.
1Scope
This Part of this European Standard specifies requirements for the nominal dimensions of hot-rolled equal and unequal leg angles. This European Standard does not apply to angles with square roots, nor to equal and unequal leg angles rolled from stainless steel. Tolerances for equal and unequal leg angles are given in EN 10056-2.
2Normative 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 10079Definition of steel products
EN 10056-2Structural steel equal and unequal leg angles – Part 2: Tolerances on shape and dimensions
3Definitions
For the purposes of this European Standard, the definitions in EN 10079 apply.
4Designation
The designation of hot-rolled equal and unequal angles shall comprise:1)the letter L for angles;
2)the number of this European Standard;3)the leg length, a  (in mm);
4)the leg length, a  or b  (in mm);5)the leg thickness, t  (in mm).EXAMPLE:
L EN 10056-1 – 70 × 70 × 7 or L EN 10056-1 – 50 × 30 × 5
5Dimensions
Hot-rolled equal and unequal angles complying with this European Standard shall be delivered with the dimen-sions given in tables 1 and 2 and illustrated in figures 1 and 2.
