7 Page 2 EN : 996 Foreword This European standard has been drawn up by CEN/TC 32, Aluminium and aluminium alloys, of which the Secretariat is held by AFNOR. 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publication of an identical text or by endorsement, at the latest by February 997, and conflicting standards shall be withdrawn at the latest by February 997. This standard is part of a set of three standards which are the following: EN 683- : 996 Aluminium and aluminium alloys Finstock Part : Technical conditions for inspection and delivery EN : 996 Aluminium and aluminium alloys Finstock Part 2: Mechanical properties EN : 996 Aluminium and aluminium alloys Finstock Part 3: Tolerances on dimensions and form According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

8 Page 3 EN : 996 Scope This Part of EN 683 specifies the mechanical properties of wrought aluminium and aluminium alloy finstock. It applies to flat rolled products. The chemical composition limits of these materials are specified in EN The designations of wrought aluminium and aluminium alloys and the temper designations used in this standard are specified in EN 573- and EN and EN 55 respectively. 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.

Parallel sided test pieces shall be prepared using a double bladed cutter or guillotine (see figure 2) or a precision ground sample shear of `punch and die' construction. Shouldered test pieces shall have a similar sample shear or can be machined in packs using a milling-type cutter. Parallel sided test pieces shall have a width of 5 mm ± 0, mm and a gauge length of 50 mm ± mm or 00 mm ± mm. Shouldered test pieces shall be in accordance with EN During the part of the test to determine proof stress, the strain rate shall not exceed 0 /s. The strain rate can then be increased until rupture but it shall not exceed 50 of the gauge length per minute. Considering the difficulty in marking thin gauge material, the gauge length may be measured by the distance between the grips of the testing machine. The elongation is then determined from the difference in the distance between the grips before testing and at fracture, or by direct reading from the load/crosshead-displacement diagram when available. This provision only applies to parallel-sided test pieces. 4 Mechanical properties Mechanical property values for aluminium and aluminium alloys in finstock form are specified in table. For the elongation measurement, two different gauge lengths may be used. The choice of gauge length (either 50 mm or 00 mm) shall be at the discretion of the supplier unless otherwise agreed; nevertheless, the supplier shall inform the purchaser of the length used. 5 Rounding of test results Test results shall be rounded in accordance with the rounding rules given in the annex A.
