13、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 text or by endorsement, at the latest by March 2008, and conflicting national standards shall be with
14、drawn 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, Aluminium and aluminium alloys Chemical composition and form of wrought products Part 5: Codification of sta
15、ndardized 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 designation system Part 2: Chemical symbol based designation system Part 3: Chemical composition and form of
16、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 rights. CEN shall not be held responsible for identifying any or all such patent rights. CEN/TC 132 a
17、ffirms 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 removed from the corresponding standard. According to the CEN/CENELEC Internal Regulations, the national
18、standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Polan
19、d, 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 description of products, above all in the field of design, scheduling of operations, material suppli
20、es 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 system proposed in the present document provides a standardized pattern from which a rapid and unequivoc
21、al 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 drawings or part lists. It is not intended to replace the technical conditions of inspection and deliv
22、ery 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 information. NOTE Codification is usually required for technical drawings. It does not apply to castings, ca
23、st 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 dated references, only the edition cited applies. For undated references, the latest edition of the refe
24、renced 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 from wrought products Specification EN 573-3, Aluminium and aluminium alloys Chemical composition and
25、 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, rectangular and shaped tubes EN 12258-1:1998, Aluminium and aluminium alloys Terms and definitions Part
26、 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 abbreviated form important technical data required for a product order or tender. In the product standards,
27、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 affected by this codification standard. Each codification consists of a “Description Block“ and an “Ident
28、ification 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 system EN 573-5:2007 (E) 6 4.2 Description Block Codification according to this document shall be restr
29、icted 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 be taken preferably from the title of the standard or the descriptors, the one which best characteri
30、zes 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 Identification Block 4.3.1 Structure of Identification Block The Identification Block consists of two
31、 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 the Individual Item Block. 4.3.2 European Standard Number Block If the European Standard of a product
32、 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 inspection and delivery, mechanical properties and additional properties laid down in the relevant parts of
33、 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 the first, second and third characteristic should be separated by a hyphen (): material designation;
34、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 forgings or extruded profiles, letters in front of figures are allowed. Reference to drawings may be
35、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 plain language as characteristics, e.g. for shape and type or design data, shall be coded to prevent th
36、eir 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, designations and cods to be used in the Identification Block Material designation specified in EN 573-3 shall b
37、e 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, C , according to Table 1, shall be used. For sheet and plate the code “RCT“ shall not be used. All d
38、imensions 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 Table 1, the reference code of the drawing shall be written instead of the designation. EN 573-5:2007
39、 (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 given according to the relative standards. For circles only the thickness and the circle diameter sh
40、all 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 supplier and purchaser, for round tubes and for sheet, strip and plate. For any other form of products, re
41、ference to drawings shall be used.

When quoting the c
46、haracteristic 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 after the corresponding data. The following examples are listed in sections according to the product gro
47、ups and one example is listed only. 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.
