Technological development may require the use of terms additional to those listed. 4.2 Page 1:

22、Title of the material standard The title shall give sufficient information to unambiguously identify the semi-finished product, in the use condition (see 4.5.11). Consequently: 1. the same title shall not be used for different material standards; 2. overlapping of mechanical property limits for othe

23、rwise identical material standards shall not normally be permitted. prEN 4500-001:2011 (E) 6 Each part of the title shall consist of one or several different lines: aerospace series; the family of metallic material, followed by the designation of the metallic material in accordance with EN 2032-1; m

24、ethod of melting, if appropriate (except for titanium and titanium alloys); use condition and heat treatment; the forms written in singular, or plural, in conformity with the language used and, if appropriate, the method of production and/or final intended use; limiting dimensions; relevant mechanic

25、al property or physical property limits, if appropriate. 4.3 Page 2 Blank, in principle. Foreword, if necessary. 4.4 Page 3 Clause 0: Introduction This clause shall read: “This standard is part of the series of EN metallic material standards for aerospace applications. The general organization of th

26、is series is described in EN 4258“; “This standard has been prepared in accordance with EN 4500-2“ or “EN 4500-003“ or “EN 4500-004“ or “EN 4500-005“ or “EN 4500-6“. Clause 1: Scope This clause shall read: “This standard specifies the requirements relating to:“ Repeat all information in the title, p

27、resented in the same format, followed by “for aerospace applications“. If necessary, further information may be added to clarify the scope. NOTE Other designation: AISI 304L. Only the chemical composition of this standard must be considered. Clause 2: Normative references This clause shall read: “Th

28、e 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 referenced document (including any amendments) applies.“. Followed by the list of documents, with their tit

29、les, to which reference is made in the text. prEN 4500-001:2011 (E) 7 4.5 Page 4: corresponds to form 1 given in Annex A 4.5.1 General Form 1 is a fixed format. If there is insufficient space on a line: use notes; repeat the line(s). Complete the relevant lines with the pertinent requirements, accor

30、ding to 4.5.2 to 4.5.24. Requirements (test method, frequency of testing, sample type, test piece definition, heat treatment condition of test piece, testing condition) that are already specified in the technical specification or the test method standard called up by the technical specification refe

31、renced on line 5, shall not be repeated, in this case write “See EN XXXX“. If it is necessary to modify the requirements of the technical specification or test method, use notes in the table. A hyphen shall be marked on those lines that are not required. Values other than those mentioned on lines 2,

32、 12, 19, 21, 23 and 25 shall be preceded by a sign depending on whether they are minimum or maximum values (, , , ). Where more than one test method; test condition; test value. is stated, all are mandatory except when indicated by a note, which one is to be used. Symbols for sizes and units: See IS

33、O 80000-1, ISO 80000-2, ISO 80000-3, ISO 80000-4, ISO 80000-5 and ISO 80000-10. Specific examples are given for each family of metallic material in EN 4500-2 to EN 4500-6. 4.5.2 Page 4, line 1: Material designation This line shall give the family of the metallic material and the conventional designa

34、tion, in accordance with EN 2032-1. 4.5.3 Page 4, line 2: Chemical composition The chemical symbols of the elements shall be written in the first line of boxes, in accordance with established conventions (see ISO 80000-10). The second line of boxes shall indicate the minimum content of that element.

35、 The third line of boxes shall indicate the maximum content of that element. prEN 4500-001:2011 (E) 8 The mass content of alloying elements shall be explicitly defined by the specified values in the second and third line of the boxes. The mass content of other identified elements (e.g. trace element

36、s, impurities, base metal for filler metals, etc.) shall only be specified by a minimum and/or a maximum value, as applicable. When other elements are not identified, indicate them as “others“, subdivided into “each“ and “total“. For each element shown, the absence of a value shall be indicated by m

37、eans of a hyphen. Ratio and/or total content of two or more elements may be specified on line 2. All values V shall be expressed in mass percentage. When very low values are expressed in mass parts per million, a note shall be used to define the abbreviation “p.p.m.“. The following rules shall be ob

38、served for the value V: Vmin.or Vmax. 0,01 % express Vmin.and Vmax.in “p.p.m.“; Vmin. 0,01 % express in %. The number of decimal places written shall be consistent with the accuracy required. The base metal shall be indicated in the last column of the second line of boxes by means of a minimum and/o

39、r maximum value or by the expression “base“. The standard order for presentation of the elements for each family of metallic materials is specified in EN 4500-2 to EN 4500-6. 4.5.4 Page 4, line 3: Method of melting Line 3 shall be completed when one or several specific methods of melting are require

40、d. Modification to line 3 (by addition of further melting methods or changes to melting methods) shall not change the EN reference number if the requirements defined in lines 12 to 99 do not change. When several methods of melting can be used under the same EN reference (i.e. the requirements in the

41、 lines 12 to 99 do not change), line 3 shall contain a note which will state in line 98 ; “the melting route for qualification and delivery of products shall be identical“. 4.5.5 Page 4, line 4.1: Form The form or similar forms of the products covered by the standard shall be stated using the same t

42、erms as specified in the title. 4.5.6 Page 4, line 4.2: Method of production The method or methods of production shall be indicated, if necessary. In the case of castings or forgings, indicate requirements for remelting stock or forging stock as follows: cast from remelting stock EN XXXX; or forged

43、from forging stock EN XXXX. prEN 4500-001:2011 (E) 9 4.5.7 Page 4, line 4.3: Limit dimension(s) (mm) The dimensions to which limits apply shall be indicated. The following symbols shall be used as applicable: “a“ for thickness; “b“ for width; “l“ for length; “D“ for outside diameter; “d“ for inside

44、diameter; “De“ for the equivalent diameter. 4.5.8 Page 4, line 5: Technical specification This line shall indicate the applicable technical specification. 4.5.9 Page 4, line 6.1: Delivery condition and Heat treatment The first line indicates the nature of the thermo-mechanical operations applied to

45、the product, in the order in which they are applied, completed, if appropriate, by a particular term qualifying the surface condition of the product. The wording used to describe these operations shall be taken from EN 2032-2. More than one delivery condition may be indicated, they shall be separate

46、d by vertical lines. A second line shall indicate the quantitative values along which the above operations are performed. Each part of a heat treatment step shall be separated by a slash ( / ). The various steps of a heat treatment shall be linked by means of the plus sign ( ). Abbreviations and sym

47、bols may be used in the wording of these two lines chosen from Table 1. All other terms shall be written in full. prEN 4500-001:2011 (E) 10 Table 1 Term Abbreviations and symbols French English German temperature time t t t day d d d hour h h h minute min min min second s s s water quench TE WQ in p

49、oducts not intended for subsequent working, the use condition corresponds to the heat treatment condition of the final component made from these semi-finished products. In other cases, the use condition designates the heat treatment condition of the semi-finished product before further working (e.g. forging stock, remelting stock, semi-finished product used for fasteners). Only one use condition shall be stated in the material standard
