NOTE 2 The inspection representatives validate the inspection and te
26、st results. Inspection and testing can also be carried out by the manufacturing department. 3.4 non-specific inspection inspection carried out by the manufacturer in accordance with his own procedures to assess whether products defined by the same product specification and made by the same manufactu
27、ring process are in compliance with the requirements of the order or not NOTE The products inspected may not necessarily be the products actually supplied. 3.5 product analysis chemical analysis carried out on a sample of the product 3.6 rough specimen part of the sample having undergone forming and
28、/or machining, followed by heat treatment where appropriate, for the purpose of producing test pieces (see Figure 1) 3.7 sample sufficient quantity of material taken from the sample product for the purposes of producing one or more test pieces (see Figure 1) NOTE In certain cases, the sample can be
29、the sample product itself or the rough specimen. 3.8 sample product item (a sheet, for example) selected from a test unit for the purpose of obtaining test pieces (see Figure 1) NOTE In certain cases the sample product can be the sample itself. 3.9 sequential testing group or series of tests from wh

33、 of pieces or mass of products to be accepted or rejected together, on the basis of the tests to be carried out on sample products in accordance with the requirements of the product specification or order (see Figure 1) 4 Information to be supplied by the purchaser 4.1 The purchaser shall select the
34、 steel grade, the shape of the product and the dimensions, taking the intended processing and use into account. He may take the manufacturers advice in making his choice. The order shall provide all the information necessary for describing the required product and its characteristics and details con
35、cerning delivery, e.g.: a) mass, length, area, number of pieces; b) the product form (it may be a drawing number for example); c) the nominal/specified dimensions; d) the tolerances on the characteristics in a), b) and c); e) the steel designation; f) the delivery conditions (type of heat treatment,
36、 surface treatment etc.); g) the specific requirements for surface and/or internal quality (see 7.4); h) the type of inspection document (see EN 10204) if required; i) the inspection requirements when not specified in the product specification (see Clause 8); j) the requirements for marking, packing
37、 and loading; k) any optional (supplementary) requirements provided for by the specification to apply. 4.2 The information in 4.1 shall be specified either by reference to one or more standards or, in the absence of a standard, by stipulation of the required characteristics and conditions. If, in an
38、 order, reference is made to a given standard without specifying its edition date, this reference shall be interpreted as being the latest edition at the date of the order acknowledgment. 5 Manufacturing process The manufacturing process shall be left to the discretion of the manufacturer unless oth
39、erwise agreed at the time of enquiry and order or otherwise specified in the product specification. NOTE The manufacturing process covers all operations up to the delivery of the product. 6 Supply by an intermediary When a product is supplied by an intermediary, he shall submit to the purchaser, wit
40、hout any changes to it, the manufacturers documentation. This documentation from the manufacturer shall be accompanied by suitable means of identification of the product, in order to ensure the traceability between the product and the documentation (see Clause 10).

This also applies to all special requirements given in the order and n
42、ot defined in the manufacturers documentation. NOTE Any organization which during processing changes the metallurgical state of the product is considered as a product or material manufacturer. 7 Requirements 7.1 General The products shall comply with the requirements of the order. Consequently, the
43、manufacturer shall carry out appropriate process control and inspection to ensure that the delivery complies with the requirements of the order, irrespective of the type of inspection document required (see Clause 8). NOTE Examples for quality management systems can be found in appropriate documents
44、 e.g. EN ISO 9001. 7.2 Chemical composition Requirements concerning the chemical composition shall be considered to refer to the cast (heat) analysis unless they refer expressly to the product analysis. 7.3 Mechanical properties 7.3.1 Where, in the product specification, the mechanical properties a
45、re specified by dimensional categories e.g. based on thickness or diameter, the dimension to be considered is the nominal/specified dimension of the product at the prescribed location for taking samples for mechanical tests. 7.3.2 In the absence of any specification in the order or the product speci
46、fication, the mechanical properties relate to the as-delivered condition of the products. 7.3.3 Where an impact energy value is specified, without any further information, it shall be interpreted as representing the average value of those individual tests which shall be assessed as described in 8.3.
47、4.2. 7.4 Surface and internal quality 7.4.1 General All products shall have a finish appropriate to the manufacturing route. Minor surface and internal discontinuities which may occur under normal manufacturing conditions shall not be a basis for rejection. Detailed requirements referring to the sur
48、face and internal quality shall, where appropriate, be agreed at the time of enquiry and order, by reference to the appropriate European Standard or other relevant standard if no European Standard exists. 7.4.2 Detection of discontinuities When special techniques (radiography, ultrasonics, magnetic
49、detection etc.) are required to detect discontinuities, they shall, as well as the test frequency and the acceptance criteria, be as specified in the product specification or as agreed at the time of enquiry and order. 7.4.3 Removal of discontinuities Surface discontinuities may be removed by appropriate means provided that the dimensions and properties of the product remain within the limits specified in either the order, product specification, dimensional standard or surface quality standard.
