ISO 6361-1-2011 pdf free download.Wrought aluminium and aluminium alloys — Sheets, strips and plates — Part 1: Technical conditions for inspection and delivery.
5.7 Dimensional tolerances The dimensions and form tolerances shall be in conformity with ISO 6361-3 for strip and ISO 6361-4 for sheet, or with the International Standard agreed between the supplier and the purchaser and stated on the order. Unless otherwise agreed, the purchaser may only reject those products having dimensions not complying with the specified tolerances.
6 Test procedure
6.1 Sampling
6.1.1 Chemical analysis The specimens for chemical analysis shall be taken at the time of casting. Their shape and conditions of production (mould design, cooling rate, mass, etc.) shall be so designed that their composition is homogeneous, and shall be suitable for the method of analysis.
6.1.2 Specimens for mechanical testing 6.1.2.1 Location and size Specimens shall be taken from samples in such a way that it is possible to orientate the test pieces in relation to the product, as specified in 6.1.2.2. The specimens shall be large enough to allow the manufacture of sufficient test pieces for the required tests, and for any retests which may be required.
6.1.2.2 Orientation of specimens Normally, tests in the transverse (or long transverse for plate) direction are required. If the width is insufficient (less than 300 mm) to obtain a transverse specimen, then tests in the longitudinal direction are permitted.
6.1.2.3 Identification of specimens Each specimen shall be marked in such a manner that, after removal, it is still possible to identify the product from which it was taken and its location and orientation. If, during the course of subsequent operations, removal of the markings cannot be avoided, new markings shall be made before the originals are removed.
6.1.2.4 Preparation of specimens Specimens shall be taken from the sample after completion of all the mechanical and heat treatments that the product has to undergo before delivery, and which may influence the mechanical properties of the metal. In cases where this is not possible, the sample or specimens may be taken at an earlier stage, but they shall be subjected to the same treatment as that to which it is intended to submit the product concerned. NOTE If the purchaser intends to convert the material to a final temper which is different from the “as supplied” temper, then additional testing can be requested by the purchaser in order to satisfy himself that the material is capable of meeting the specified properties of the final temper. It is only necessary for the supplier to confirm that selected samples, heat-treated using the supplier’s laboratory conditions, meet the properties specified for the final temper required by the purchaser. Cutting shall be carried out in such a manner that it does not change the characteristics of the part prepared. Thus, the dimensions of the specimens shall provide an adequate machining allowance to permit removal of the zone affected by cutting.ISO 6361-1 pdf download.
