National foreword This British Standard is the English language version of EN 10056-1:1997. It supersedes BS 4848-4:1972 which is withdrawn The UK participation in its preparation was entrusted to Technical Committee ISE/13, Structural steel sections, which has the responsibility to: Ð aid enquirers to understand the text; Ð present to the responsible European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; Ð monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled ªInternational Standards Correspondence Indexº, or by using the ªFindº facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

This European Standard was approved by CEN on 21 December 1997. CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CEN member. This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the Central Secretariat has the same status as the official versions. CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

Foreword This European Standard has been prepared by Technical Committee ECISS/TC11, 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, at the latest by February 1999, and conflicting national standards shall be withdrawn at the latest by February 1999. The discussions within ECISS/TC11 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 organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

4 Designation

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. These requirements do not apply to equal and unequal leg angles rolled from stainless steel. Tolerances for equal and unequal leg angles are given in EN 10056-2.

The designation of the hot-rolled equal and unequal leg 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).

2 Normative 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 10079, Definition of steel products. EN 10056-2, Structural steel equal and unequal leg angles Ð Part 2: Tolerances on shape and dimensions.

EXAMPLE Either: L EN 10056-1-70 3 70 3 7; or L EN 10056-1-50 3 30 3 5.

5 Dimensions Hot-rolled equal and unequal leg angles complying with this European Standard shall be delivered with the dimensions given in Tables 1 and 2 and illustrated in Figures 1 and 2.

3 Definitions For the purposes of this European Standard the definitions in EN 10079 apply.

is the sectional area, in square centimetres; is the thickness, in millimetres; is the root radius, in millimetres; is the toe radius, in millimetres (sectional properties have been calculated assuming a toe radius equal to half the root radius); is the leg length, in millimetres; is moment of inertia; is the section modulus; is the radius of gyration (the subscripts x, y, u and v denote the axis). Mass is calculated on the basis of density of steel of 7,85 kg/dm 3.

NOTE 1 The sectional area has been calculated using the formula: S = [t(2a 2 t) + 0,214 6(rroot2 2 2rtoe2)]/100 where
