24、998 and the following applies. 3.1 finstock flat, cold rolled product of rectangular cross section and thickness in the range 60 m to 400 m suitable for heat exchanger applications 4 Ordering information The order shall specify the product required and shall contain the following information: a) typ
25、e and form of product: the designation of the aluminium or aluminium alloy; the form of the product; b) temper designation of the material to be delivered as specified in EN 515; c) number of this European Standard (EN 683-1) or separate specification, if any; EN 683-1:2006 (E) 5 d) dimensions of th
26、e product: thickness; width and type of specified tolerance on width as defined in EN 683-3 (symmetrical, only plus, only minus), or as agreed between supplier and purchaser; internal and external diameter of the coil/reel; core size and type; e) quantity (mass); f) any special requirements agreed b
27、etween supplier and purchaser, e.g.: test certificates and inspection reports; marking of the products, e.g. identification; reference to drawings, e.g. for packaging, coil axis orientation, etc.; whether surface degreasing is required. Where special requirements are specified, the application shall
28、 be stated. 5 Requirements 5.1 Production and manufacturing processes Unless otherwise specified in the order, the production and manufacturing processes shall be left to the discretion of the supplier. Unless it is explicitly stated in the order, no obligation shall be placed on the supplier to use
29、 the same processes for subsequent and similar orders. 5.2 Quality control The manufacturer shall establish and maintain a quality management system, which should be at least equivalent to EN ISO 9001. The manufacturer shall establish and maintain inspection plans defining all inspections and tests
30、to be performed on the product to fulfil the requirements of this standard and any other requirement agreed according to Clause 6 of the present standard, their frequency and the type of record to be established. The inspection plan shall specify for each inspection or test whether it is to be perfo
31、rmed per cast, per heat treatment batch, per inspection lot as defined in EN 12258-1 or per any other lot of importance. The inspection plan shall conform as a minimum to the test procedures and test requirements stipulated in this standard. The inspection plan shall include additional schemes for a
32、ppropriate process control. If required the inspection plan shall be submitted to the purchaser for approval before start of production. The manufacturer shall be responsible for carrying out all inspections and tests required by this standard, prior to the shipment of the product. If the purchaser
33、wishes to inspect the product at the manufacturers site of production, he shall stipulate this at the time of placing the order. The extent of inspections shall be in accordance with Clause 6 of the present standard. Unless explicitly stated quality controls and inspections shall be performed on ins
34、pection lots. Products included in one inspection lot shall be manufactured in the same production unit. EN 683-1:2006 (E) 6 5.3 Chemical composition The chemical composition shall be in conformity with the requirements specified in EN 573-3, unless otherwise agreed between supplier and purchaser. 5
35、.4 Mechanical properties The mechanical properties shall be in conformity with EN 683-2, unless otherwise agreed between supplier and purchaser. 5.5 Freedom from defects The product shall be free from defects prejudicial to its suitable and proper use. 5.6 Tolerances on dimensions and form The toler
36、ances on dimensions and form shall be in conformity with EN 683-3. 5.7 Special properties Any special property requirements shall be agreed between purchaser and supplier. 6 Test procedure 6.1 Sampling 6.1.1 Samples for chemical analysis Sampling shall be carried out at the time of casting according
37、 to EN 14361. The average content of each sample shall be within the specification for the chemical composition. NOTE EN 14361 includes criteria how to determine number, volume and shape of samples, about time and location of sampling and about the design and maintenance of the tools, in order to ma
38、ke sure that the average chemical composition of the sample is representative of the average chemical composition of the whole melt. 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 i
39、n relation to the product, as specified in 6.1.2.2. The specimens shall be large enough to allow manufacture of the test pieces necessary to carry out the required tests and shall include sufficient metal to allow manufacture of test pieces for any retests required. 6.1.2.2 Orientation Specimens sha
40、ll be taken in such a manner that the test pieces can be prepared in the longitudinal direction. 6.1.2.3 Identification Each specimen shall be identified in such a way that after removal, it is still possible to identify the product from which it was taken and its location and orientation. If during
41、 the course of subsequent operations removal of the markings cannot be avoided, new markings shall be made before the originals are removed. EN 683-1:2006 (E) 7 6.1.2.4 Preparation Specimens shall be taken from the sample after completion of all the mechanical and heat treatment operations that the
42、product has to undergo before delivery and which can 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 produc
43、t concerned. Cutting shall be carried out in such a manner that it does not change the characteristics of the part of the specimen from which the test pieces are to be prepared. Thus, the dimensions of the specimens shall provide an adequate allowance to permit removal of the zone affected by cuttin
44、g. Specimens shall not be treated in any way that alters their mechanical properties. 6.1.2.5 Number One specimen shall be taken from each inspection lot of 10 000 kg or part thereof. For single coils weighing more than 10 000 kg each, only one specimen per coil shall be taken. 6.1.3 Test pieces for
45、 tensile test 6.1.3.1 Identification 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. If a test piece is identified by stamping, this shall not be in a place or m
46、anner which can interfere with subsequent testing. Where it is not convenient to mark a test piece, an identification tag may be attached. 6.1.3.2 Number One test piece shall be taken from each specimen. 6.1.3.3 Type Flat test pieces shall be used for all thicknesses covered by EN 683-2. The test pi
47、ece shall be prepared so that both rolled surfaces are included undisturbed. 6.1.3.4 Machining Any machining necessary shall be carried out in such a manner that it does not change the characteristics of the metal in the test piece. 6.2 Methods of testing 6.2.1 Analysis of chemical composition The r
48、anges of application and the accuracy of the test procedure used shall be validated and proved by the supplier. In case of dispute concerning the chemical composition, referee analysis shall be carried out in accordance with EN 14242. NOTE For the rapid determination of the chemical composition diff
49、erent spectral analysis methods are used (e.g. S-OES, XRF, GDOES). For S-OES see EN 14726. EN 683-1:2006 (E) 8 6.2.2 Mechanical and physical tests The tensile test shall be carried out in accordance with EN 683-2. 6.2.3 Measurement of dimensions The dimensions shall be measured by means of measuring instruments which are capable of measuring to the accuracy required by the dimensions and the tolerances on dimensions specified in EN 683-3. All dimensions shall be checked at the ambient temperature of the wo
