— internal and external diameters of the coil or reel;
— core size and type;
For the further processing of the sheet, usually one dimension is critical, demanding a tight tolerance, As the width tolerance is usually the tighter one, the purchaser shall state the critical dimension as the width of the sheet,
Designation of the sheet dimension shall always be In the following sequence: thickness x width x length
It is recommended that the width be indicated by a H’ after the actual drension if the width is greater than the length, (see 6.2.2, Figure 1).

4.2 RequIrements
4.2.1 Production and manufacturing processes
Unless otherwise specified in the order, the production and manufacturing processes shall be left to the discretion of the manufacturer. Any changes in the processes for subsequent and similar orders which significantly affect the properties of the product, whether or not specified in this standard, shall be agreed by the purchaser
4.2.2 Quality control
The supplier shall be responsible for the performance of all inspection and tests required by this European
Standard and/or the particular specification prior to the shipment of the product.
4.2.3 Chemical composition
The chemical composition shall comply with the requirements as specified in EN 573-3 and for alloy EN AW-5006 as specified in Annex D and EN 602.
4.2.4 Freedom from defects
The product shall be free from defects prejudicial to its suitable and proper use
4.3 Test procedure
4.3.1 Sampling
4.3.1.1 Samples for chemical analysis
Sampling shall be carried out at the time of casting according to EN 14361 The average content of each sample shall be within the specification for the chemical composition,
NOTE EN 14361 dudes ciuteria for how to determine the number, volume and shape of samples. the time and locadon of sampling and the design and maintenance of the tools, in cider to make sure that the average chemical coinposiLion of the sampie represents the average chemical coniposibon of the ole melt
4.3.1.2 Specimens for mechanical testing
4.3.1.2.1 Number of specimens
Unless otherwise specified, at least one specimen shall be taken from ead master coil of an inspection lot
4.3.1.2.2 Location and size
Specimens shall be taken from samples in such a way that it is possible to orientate the test pieces parallel with the rolling direction (longitudinal drection).
The specimens shal be sufficiently large enough to allow the manufacture of the test pieces necessary to carry out the required tests and shall include sufficient metal to allow the manufacture of test pieces for any retests required
4.3.1.2.3 identification of specimens
Each specimen shall be marked in such a way that, after removal, It Is still possible to identify the product from
whèch It was taken and Its location and orientation.
4.3.1.3 Test pieces for tensile testing
4.3.1.3.1 Number of test pieces
One test piece shall be taken from each specimen for the tensile test. The shapes and dimensions for tensile
test pieces shall comply with EN 10002-1.
4.3.1.3.2 Identification of the test pieces
Each test piece shall be marked wi such a manner that it is possible to identify the inspection lot from which it was taken and if required, its location and orientation in the product
4.3.1.3.3 Machining
Any machinang necessary shal be carried out in such a manner that it does not change the characteristics of
the metal in the test piece,
4.3.1.4 Test pieces for other tests
For any other tests (e.g eanng. thickness or weight of coatings, lubncants) the procedures shall be agreed between the supplier and purchaser.
