It does not apply to semi-finished rolled products in coiled form to be subjected to further rolling (reroll stock) or to special products such as corrugated, embossed, painted, etc. sheets and strips or to special applica
35、tions such as aerospace, can stock, finstock, etc. which are dealt with in separate European Standards. The systems for designating these materials are described in EN 573-1 and EN 573-2. Their chemical composition limits are specified in EN 573-3. Mechanical property limits are specified for all Cl
36、ass A alloys, as defined in EN 573-4. Temper designations are defined in EN 515. NOTE Some of the products listed in the present standard can be subject to patent or patent applications, and their listing herein does not in any way imply the granting of a licence under such patent right. CEN/TC 132
37、affirms it is its policy that in the case when a patentee refuses to grant licences on standardised standard products under reasonable and not discriminatory conditions then this product shall be removed from the corresponding standard. 2 Normative references The following referenced documents are i

In both cases the mechanical property limits specified in Tables 2 to 39 shall apply; machined test-piece
44、s of rectangular or circular cross-section (as applicable) shall be used; for specified thicknesses up to and including 12,5 mm the test-piece shall have a rectangular (or square) cross-section.
