This European Standard was approved by CEN on 1996-12-19. 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, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

1 Scope

3.2.1.2 Length

This Part of this standard specifies the tolerances on dimensions and form of cast aluminium and aluminium alloy forging stock for general engineering applications. The chemical compositions for these alloys are specified in EN 573-3. The technical conditions for  inspection and delivery of these products are specified in EN 604-1.

The measurement shall be taken overall. The limit deviations on the nominal length shall be: ± ± 3 mm for ingot lengths not greater than 1200 mm; ± ± 15 mm for ingot lengths greater than 1200 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 573-3

Sawn ends of ingots shall be perpendicular to the longitudinal axis to (90  ±  1)Ê. 3.3.1.2  Straightness (as cast ingot only)

3 Tolerances on dimensions and form 3.1 General

The tolerances stated below shall apply to round ingots, as cast or scalped on diameter and sawn to length and to rectangular ingots, scalped on faces and sawn to length and width.

The deflection measured on any generating line of the ingot shall be less than 3 mm per metre. The total deviation over the full length of the ingot shall not exceed 15 mm. 3.3.2 Rectangular ingots (scalped) 3.3.2.1  Perpendicularity

3.2.1 Round ingots (as cast or scalped)

Sawn faces of ingots shall be perpendicular to the longitudinal or transverse axis, as applicable, to (90  ±  1)Ê.

3.2.1.1  Diameter 

3.3.2.2  Flatness

The measurements shall be taken at the two sawn ends on two diameters 90Ê apart. The limit deviations on the nominal diameter shall be: a) as cast:

The deflection measured in any direction on any face of the ingot shall be less than 2 mm per metre.

3.2 Tolerances on dimensions
