13、 EN 573-5:2007 (E) 3 Foreword This document (EN 573-5:2007) has been prepared by Technical Committee CEN/TC 132 “Aluminium and aluminium alloys”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical
14、text or by endorsement, at the latest by March 2008, and conflicting national standards shall be withdrawn at the latest by March 2008. Within its programme of work, Technical Committee CEN/TC 132 entrusted CEN/TC 132/WG 7 “Sheet, strip and plate“ to prepare the following standard: EN 573-5, Alumini
15、um and aluminium alloys Chemical composition and form of wrought products Part 5: Codification of standardized wrought products. EN 573 comprises the following parts under the general title “Aluminium and aluminium alloys Chemical composition and form of wrought products“: Part 1: Numerical designat
16、ion system Part 2: Chemical symbol based designation system Part 3: Chemical composition and form of products Part 4: Forms of products Part 5: Codification of standardized wrought products Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
17、rights. CEN shall not be held responsible for identifying any or all such patent rights. CEN/TC 132 affirms it is its policy that in the case when a patentee refuses to grant licences on standardised standard products under reasonable and not discriminatory conditions then this product shall be remo
18、ved from the corresponding standard. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greec
19、e, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 573-5:2007 (E) 4 Introduction The significance of a standard codification lies in the rational, unambiguous
20、 description of products, above all in the field of design, scheduling of operations, material supplies and in the field of offering and ordering. The exchange of information between companies and plants made possible by product codification becomes more and more important for communication. The sys
21、tem proposed in the present document provides a standardized pattern from which a rapid and unequivocal description of a product is possible, instead of a lengthy verbal description. It can be used advantageously in cases where the reference to semi products should be short and consistent, such as d
22、rawings or part lists. It is not intended to replace the technical conditions of inspection and delivery as laid down in the specific product standards. EN 573-5:2007 (E) 5 1 Scope This document specifies the codification of some standardized semifinished wrought products for use in ordering informa
23、tion. NOTE Codification is usually required for technical drawings. It does not apply to castings, cast forging stock, rolling ingots, extrusion billets and ingots for remelting. 2 Normative references The following referenced documents are indispensable for the application of this document. For dat
24、ed references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 515, Aluminium and aluminium alloys Wrought products Temper designations EN 570, Aluminium and aluminium alloys Impact extrusion slugs obtained
25、from wrought products Specification EN 573-3, Aluminium and aluminium alloys Chemical composition and form of wrought products Part 3: Chemical composition and form of products EN 1592-4, Aluminium and aluminium alloys - HF seam welded tubes - Part 4: Tolerances on dimensions and form for square, re
26、ctangular and shaped tubes EN 12258-1:1998, Aluminium and aluminium alloys Terms and definitions Part 1: General terms 3 Terms and definitions For the purposes of this document the terms and definitions given in EN 12258-1:1998 apply. 4 Codification system 4.1 General This system contains in abbrevi
27、ated form important technical data required for a product order or tender. In the product standards, where technical conditions for inspection and delivery are specified, there are included additional specifications needed for an order or tender. The requirements of these standards shall not be affe
28、cted by this codification standard. Each codification consists of a “Description Block“ and an “Identification Block“. The system is illustrated in Figure 1. Codification Identification Block Description Block European Standard Number Block Individual Item Block Figure 1 Structure of codification sy
29、stem EN 573-5:2007 (E) 6 4.2 Description Block Codification according to this document shall be restricted to the products specified in EN 573-3 and the relevant product standards. The definitions of these products are specified in EN 12258-1. The description shall be as short as possible and should
30、 be taken preferably from the title of the standard or the descriptors, the one which best characterizes the standardized product. The description shall be translated in the national versions of the European Standard since the product can be identified by the European Standard number block too. 4.3
31、Identification Block 4.3.1 Structure of Identification Block The Identification Block consists of two consecutive blocks of characters, the European Standard Number Block and the Individual Item Block. In order to mark the division between the two blocks, a hyphen () shall be the first character of
32、the Individual Item Block. 4.3.2 European Standard Number Block If the European Standard of a product consists of several parts issued, the number of the relevant part where tolerances on dimensions and form are specified shall be taken. All the requirements concerning technical conditions of inspec
33、tion and delivery, mechanical properties and additional properties laid down in the relevant parts of the standard shall be applicable. 4.3.3 Individual Item Block In order to allow an unambiguous coding of the standardized product the characteristics should be given in the following sequence where
34、the first, second and third characteristic should be separated by a hyphen (): material designation; temper designation; parameters, e.g. dimensions (thickness width length). Numerical values for parameters shall be used absolutely. In cases where no dimensions can be coded, e.g. drawing number for
35、forgings or extruded profiles, letters in front of figures are allowed. Reference to drawings may be coded with letters and figures, where letters should be explained by a short text outside of the codification. No symbols shall be used which could be mistaken for codification symbols. Entries in pl
36、ain language as characteristics, e.g. for shape and type or design data, shall be coded to prevent their translation into other languages. Some codifications are given in the examples and they should be standardized in the product standards when these are subject of revision. 4.3.4 Terms, designatio
37、ns and cods to be used in the Identification Block Material designation specified in EN 573-3 shall be used whenever possible. Temper designation specified in EN 515 shall be used whenever possible. For dimensions and form, the following designations, composed of a code and two or more numbers A, B,
38、 C , according to Table 1, shall be used. For sheet and plate the code “RCT“ shall not be used. All dimensions shall be specified in millimetres, with the exception of foil and finstock thicknesses which are specified in micrometers. For products of irregular cross-sections which are not covered by
39、Table 1, the reference code of the drawing shall be written instead of the designation. EN 573-5:2007 (E) 7 For coiled products and products required in random lengths only the cross-sectional dimensions shall be codified. Further specifications, e.g. related to inside diameter of the coil, shall be
40、 given according to the relative standards. For circles only the thickness and the circle diameter shall be indicated as part of the codification. For slugs the codification system shall apply as specified in EN 570. Further designation characteristics shall be used only if agreed upon between suppl
41、ier and purchaser, for round tubes and for sheet, strip and plate. For any other form of products, reference to drawings shall be used.

44、table, the reference code of the drawing should be written instead of the designation, followed by a figure describing the fixed length in millimetres or the designation “RL“ if random length is required. aIf a length is specified, this shall be considered as fixed length.

When quoting the characteristic features the same order shall be used for those appearing in the explanation as in the codification. Supplementary coded expressions shall be added in parentheses in the explanation aft

It is entrusted to the working groups of CEN/TC 132 to amend their product standards by the codification system when these standards are to be revised. EN 573-5:20
