28、ll define the product required and shall contain the following information: a) type and form of the product: form of the product (sheet or strip); surface finish (see Clause 7); application; designation of the aluminium or aluminium alloy in accordance with EN 573-3; b) metallurgical temper of the m
29、aterial: temper designation in accordance with EN 515 (see also Annex C); for H1x tempers: delivery in accordance with Table 1 and/or Table 2; c) number of this standard or a specification number or, where none exists, the properties agreed between the supplier and purchaser; d) dimensions of the pr
30、oduct, (in millimetres): thickness (to three decimal places); width; length; EN 541:2006 (E) 6 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 u
31、sually 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 width length. It is recommended that the width be indicated by a W after the actual dimension if the width is gr
32、eater than the length, (see 6.2.2, Figure 1). EXAMPLE 0,300 mm 750 mm 1 000 mm 0,300 mm 1 000 mm (W) 750 mm e) quantity: mass, area or number of pieces; f) any requirements for inspection documents; g) any special requirements for packaging: mass per coil and per packaging unit; number of sheets per
33、 stack; position of coil axis (vertical or horizontal); direction of winding (see Clause 10); design of pallet; h) any special requirements agreed between supplier and purchaser: marking of products; flagging of joints. 4.2 Requirements 4.2.1 Production and manufacturing processes Unless otherwise s
34、pecified 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 signifi-cantly affect the properties of the product, whether or not specified in this standard, shall be agreed
35、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
36、 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. EN 541:2006 (E) 7 4.3 Test procedure 4.3.1 Sampling 4.3.1.1 Samples for chemical analy
37、sis 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 includes criteria for how to determine the number, volume and shape of samples, the time and loca-tion of s
38、ampling and the design and maintenance of the tools, in order to make sure that the average chemical composi-tion of the sample represents the average chemical composition of the whole melt. 4.3.1.2 Specimens for mechanical testing 4.3.1.2.1 Number of specimens Unless otherwise specified, at least o
39、ne specimen shall be taken from each 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 direction). The specimens shall be sufficiently la
40、rge 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,
41、 it is still possible to identify the product from which 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 sha
42、ll comply with EN 10002-1. 4.3.1.3.2 Identification of the test pieces Each test piece shall be marked in 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 machining necessary
43、 shall 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. earing, thickness or weight of coatings, lubricants) the procedures shall be agreed between the supplier and purchaser. EN
44、541:2006 (E) 8 4.3.2 Test methods 4.3.2.1 Chemical composition The ranges of application and the accuracy of the test procedure used shall be validated and proved by the supplier. In case of a dispute concerning the chemical composition, referee analysis shall be carried out in accordance with EN 14
45、242. NOTE For rapid determination of the chemical composition, different spectral analysis methods are used (e.g. S-OES, XRF, GDOES). For S-OES see EN 14726. 4.3.2.2 Tensile test The tensile test shall be carried out in accordance with EN 10002-1 on test pieces with a reduced section 12,5 mm wide ta
46、ken parallel with the rolling direction (longitudinal direction). The elongation shall be meas-ured on an original gauge length of 50 mm. Mechanical properties after simulated lacquer stoving shall be de-termined after heat treating the test pieces at 205 C for 20 min in a laboratory furnace. For de
47、termination of compliance, yield strength and tensile strength values shall be rounded to the nearest 1 MPa and elongation values to the nearest 0,1 % using the rounding rules given in Annex B. 4.3.2.3 Measurement of dimensions The dimensions shall be measured by measuring instruments that are accur
48、ate to 1/5 of the relevant toler-ance. All dimensions shall be checked at the ambient temperature of the workshop or laboratory, and, in case of dispute, at a temperature of (20 2) C. 4.3.2.4 Earing test (anisotropy) The earing test shall be carried out either in accordance with the relevant Europea
49、n Standard or as agreed between the supplier and purchaser. 4.3.2.5 Other tests If other mechanical or physical tests are required (e.g. thickness of coatings, lubricants), these tests shall be carried out either in accordance with the relevant European Standards or as agreed between supplier and purchaser. 4.3.3 Retests 4.3.3.1 Mechanical properties If any of the test pieces first selected fail to meet the requirements for the mechanical tests, the following pro-cedure shall be applied: I
