27、 production of forgings. 3.2 cast Quantity of product cast simultaneously from the same heat. The different ingots of a cast may have different dimensions. 3.3 inspection lot Consignment or part thereof, submitted for inspection, comprising products of the same grade or alloy, form, temper, size, sh
28、ape, thickness or cross-section and processed in the same manner. 3.4 sample One or more products taken from an inspection lot. 3.5 test piece One or more pieces taken from each product in the sample and suitably prepared for test. 3.6 test Operation to which the test piece is subjected in order to
29、measure or classify a property. 4 Orders or tenders The order or tender shall define the product required and shall contain the following details : a) the form and finish of the product: the form of the product (round or rectangular ingot); whether or not the surface shall be scalped; b) the type an
30、d metallurgical condition of the material: the designation of the aluminium and aluminium alloy; the metallurgical condition for delivery (as cast or homogenized); c) the number of this European Standard; d) the dimensions of the product (thickness, width, length, diameter); e) quantity and, where a
31、pplicable, tolerances on quantity (see 5.6); f) any requirements for inspection documents; g) any special requirements agreed between the purchaser and supplier, e.g. requirement for degassing, filtration. 5 Requirements 5.1 Production and manufacturing processes The production and manufacturing pro
32、cesses shall be left to the discretion 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. 5.2 Quality control The supplier shall be responsible for the performance of all i
33、nspection 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 s
34、hall 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 Surface quality 5.4.1 Surface roughness The surface roughness
35、 of the product shall, where applicable, be agreed between purchaser and supplier and stated on the order.Page 4 EN 604-1 : 1997 BSI 1997 5.4.2 Surface finish The products shall be free from defects likely to impair the final surface finish of forgings subsequently produced. Whilst an operation desi
36、gned to mask a defect shall not be permissible, the elimination of a superficial surface defect shall be permissible, provided that the dimensional tolerances are observed. 5.5 Tolerances on dimensions and form Tolerances on dimensions and form shall comply with EN 604-2. The purchaser may only reje
37、ct those products having dimensions not complying with the specified tolerances. 5.6 Tolerances on quantity The tolerances on quantity shall be % unless 0 +20 otherwise agreed between purchaser and supplier. 5.7 Internal quality The product shall be free from internal defects which may be detrimenta
38、l to the quality of forgings subsequently produced. If special inspections or tests are required, these shall be agreed between purchaser and supplier. 6 Test method 6.1 Sampling 6.1.1 Chemical analysis The test piece for chemical analysis shall be taken at the time of casting. The shape and conditi
39、on of production (mould design, cooling rate, mass, etc.) of the test piece shall be so designed that the composition is homogeneous and be suitable for the method of analysis. 6.1.2 Number of test pieces At least one test piece shall be taken to represent each cast. 6.2 Test procedure 6.2.1 Chemica
40、l composition Methods of analysis shall be at the discretion of the supplier. In case of dispute concerning the chemical composition, reference analysis shall be carried out by the methods agreed between purchaser and supplier and the results obtained by these methods shall be accepted. If the check
41、 analysis is to be made on the cast product, as supplied, the possibility of segregation effects shall be recognized, particularly in the thicker cross-sections. In such instances, the location of the sample for check analysis shall be subject to prior agreement between purchaser and supplier. 6.2.2
42、 Measurement of dimensions The dimensions shall be measured by means of measuring instruments which are of the accuracy required by the dimensions and dimensional tolerances. All dimensions shall be checked at the ambient temperature of the workshop or laboratory, and, in case of dispute, at a tempe
43、rature between 15 C and 25 C inclusive. 6.2.3 Surface roughness Where specified surface roughness measurement shall be carried out using a method agreed between purchaser and supplier. 6.2.4 Surface finish Examination of surface appearance shall be carried out without the assistance of magnifying ap
44、paratus, on products before delivery. 7 Inspection documents 7.1 General If requested by the purchaser on the order, the supplier shall provide one of more of the following documents as applicable. These inspection documents are based on EN 10204 with modifications due to the specific needs of alumi
45、nium and aluminium alloys. The requirements of 3.1.A, 3.1.B, 3.1.C are in conformity with EN 10204. The requirements of 7.2, 7.2.1, 7.2.2 and 7.3 are specific to aluminium products. 7.2 Documents established on the basis of inspections and tests performed by qualified personnel who are involved in t
46、he manufacturing process and/or belong to the quality control department 7.2.1 Certificate of conformity Document by which the producer certifies that according to inspections and results of representative tests the products for delivery comply with the relevant standards and with the additional req
47、uirements in the order, if any. 7.2.2 Test report Document by which the producer certifies that the products for delivery comply with the requirements specified on the order. This document details the results of the current production controls carried out on identical products made using the same me
48、thod as the products for delivery but not necessarily on the products for delivery themselves.Page 5 EN 604-1 : 1997 BSI 1997 7.3 Documents established on the basis of inspections and tests performed or supervised by qualified personnel organizationally independent from the manufacturing department,
