18、 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 sllnilas orders. 5.2 Quality control The supplier shall be responsible for the performance of all inspection a
19、nd tests required by the relevant European Standard or specifcation, 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. 6.3 Chemical composition The chemical composition shall comply
20、with the requirements given in EN 573-3. If the purchaser requires content hits 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 6.4.1 Surface roughness The surface roughness of the produc
21、t shall, where applicable, be agreed between purchaser and supplier and stated on the order.

22、quently produced. Whilst an operation designed to mask a defect shall not be permissible, the elimination of a superficial surface defect shail be pennissible, provided that the dimensional tolerances are observed. 6.5 Tolerances on dimensions and form %lemces on dimensions and form shall comply wit
23、h EN 604-2. The purchaser may only reject those products having dimensions not complying with the specified tolerances. 5.6 Tolerances on quantity The tolerances on quantity shall be +2i % unless otherwise agreed between purchaser and supplier. 5.7 Internal quality The product shall be free from int
24、ernal 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 lst method 6.1 Sampling 6.1.1 Chemical analysis The test piece for chemical analysis shall be taken at the ti
25、me of casting. The shape and condition 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 ca
26、st. 6.2 Test procedure 6.2.1 Chemical 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 resdts obtained by these meth
27、ods shall be accepted If the check 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 bet
28、ween purchaser and supplier. 6.2.2 Measurement of dimensions The dimensions shall be measured by means of measuring insments which are of the acc- required by the dimensions and dimensional tolerances. All dimensions shail be checked at the ambient temperature of the workshop or laboratory, and, in
