27、ing requirements 3 Definitions For the purpose of this standard the following definitions apply: 3.1 wrought forging stock Extruded or rolled material suitable for the production of forgings. 3.2 cast Quantity of product cast simultaneously, from the same heat. The different ingots of a cast may hav
28、e different dimensions. 3.3 inspection lot Consignment, or part thereof, submitted for inspection, comprising products of the same grade or alloy, form, temper, size, shape, thickness or cross-section and processed in the same manner. 3.4 sample One or more products taken from an inspection lot. 3.5
29、 specimen One or more pieces taken from each product in the sample for the purpose of producing test pieces. 3.6 test pieces Piece taken from each specimen and suitably prepared for test. 3.7 test Operation to which the test piece is subjected in order to measure or classify a property. 4 Orders or
30、tenders The order or tender shall define the product required and shall contain the following details: a) the form of the product (extruded bar, rolled plate etc.); b) the type and metallurgical condition of the material: the designation of the aluminium and aluminium alloy; the metallurgical condit
31、ion for delivery in accordance with EN 515 (as fabricated or annealed). c) the number of this European Standard; d) the dimensions and shape of the product (thickness, width, length, diameter) and/or reference to a drawing defining the product; e) whether mechanical testing is required; f) quantity
32、and, where applicable, quantity tolerances (see 5.7); g) any requirements for inspection documents; h) any special requirements agreed between the purchaser and supplier. 5 Requirements 5.1 Production and manufacturing processes The production and manufacturing processes shall be left to the discret
33、ion of the producer. Unless it is explicitly stated otherwise in the order, no obligation shall be placed on the producer to use the same processes for subsequent and similar orders.Page 4 EN 603-1 : 1996 BSI 1997 5.2 Quality control The supplier shall be responsible for the performance of all inspe
34、ction and tests required by the relevant European Standard or specification, prior to shipment of the product. If the purchaser wishes to inspect the product at the suppliers works, he shall notify the supplier at the time of placing the order. 5.3 Chemical composition The chemical composition shall
35、 comply with the requirements given in EN 573-3. If the purchaser requires content limits for elements not specified in the above standard, these limits shall be stated on the order, after agreement between purchaser and supplier. 5.4 Mechanical properties When requested by the purchaser and stated
36、on the order, the mechanical properties of the forging stock in the metallurgical condition shall comply with those given in EN 603-2. 5.5 Surface quality 5.5.1 Surface roughness The surface roughness of the product shall be in accordance with table 1. Table 1. Surface roughness limits of forging st
37、ock Class Alloy group(s) R a mm max. 2 2xxxx (lead bearing) 4xxxx 12,5 1 1xxxx 6,3 2xxxx (lead-free) 3xxxx 5xxxx 6xxxx 7xxxx 5.5.2 Surface finish The products shall be free from defects likely to impair the final surface finish of forgings subsequently produced. Whilst an operation designed to mask
38、a defect is not permissable, the elimination of a superficial surface defect is permissable, provided that the dimensional tolerances are observed. 5.5.3 Peripheral coarse grain Where the existence of peripheral coarse grain resultant from recrystallization during heat treatment of forgings produced
39、 from extruded forging stock in certain susceptible alloys is considered likely to impair the surface quality of such forgings, a restriction, agreed between purchaser and supplier, shall be placed on this feature and stated on the order. 5.6 Tolerances on dimensions and form Tolerances on dimension
40、s and form shall comply with EN 603-3. The purchaser may only reject those products having dimensions not complying with the specified tolerances. 5.7 Quantity tolerance The quantity tolerance shall be unless otherwise % 0 +20 agreed between purchaser and supplier. 5.8 Internal quality The product s
41、hall be free from internal defects which may be detrimental to the quality of forgings subsequently produced. If special inspections or tests are required, these shall be agreed between purchaser and supplier. 6 Test procedure 6.1 Sampling 6.1.1 Specimens for chemical analysis The specimens for chem
42、ical analysis shall be taken at the time of casting. Their shape and condition of production (mould design, cooling rate, mass, etc.) shall be so designed that their composition is homogenous and be suitable for the method of analysis. At least one specimen shall be taken to represent each cast. 6.1
43、.2 Specimens for mechanical testing (where applicable) 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 sufficiently large to allow manufacture of
44、 the test pieces necessary to carry out the required tests, and shall include sufficient metal to allow manufacture of test pieces for any retests. 6.1.2.2 Orientation of specimens Specimens shall be taken in the longitudinal direction. 6.1.2.3 Identification of specimens Each specimen shall be mark
45、ed in such a manner that, after removal, it is still possible to identify the product from which it was taken, and, if required, 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 ar
46、e removed.Page 5 EN 603-1 : 1996 BSI 1997 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. Specimens of
47、 heat treatable material ordered for supply in an alternative temper condition shall be heat treated in accordance with the recommended heat treatment practice for the temper condition of final use. Cutting shall be carried out in such a manner that it does not change the characteristics of the part
48、 of the specimen from which the test pieces are to be prepared. Thus, the dimensions of the specimens shall provide an adequate machining allowance to permit removal of the zone affected by cutting. Specimens shall not be further heat treated or mechanically worked (except for machining) before bein
49、g tested. 6.1.2.5 Number of specimens The minimum rate of sampling shall be provided to represent each cast or inspection lot. 6.1.3 Test pieces for mechanical testing 6.1.3.1 Type and location Where section thicknesses permit round or flat test pieces shall be prepared. The longitudinal axis of the test piece shall be located at mid-section thickness. 6.1.3.2 Identification of test pieces Each test piece shall be marked in such a manner that it is possible to identify the inspection lot from which it w
