28、 limit dimension and equivalent diameter Dethe limit dimension is the maximum size, expressed as the equivalent diameter (De), in which the mechanical properties can be obtained at the specified test piece positions, when heat-treated in accordance with the material standard 4 Rules for drafting and

29、 presentation 4.1 General NOTE Examples given in part 2 to 6 are only intended to illustrate the rules for drafting and presentation and may not correspond to real standardized EN products. Technological development may require the use of terms additional to those listed. 4.2 Page 1: Title of the ma

30、terial 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 otherwise identical

31、 material standards shall not normally be permitted. BS EN 4500-001:2012EN 4500-001:2012 (E) 7 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;

32、 method 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 mechan

33、ical 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

34、this 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,

35、 presented in the same format, followed by “for aerospace applications“. If necessary, further information may be added to clarify the scope. NOTE Other common designation (insert designation). Clause 2: Normative references This clause shall read: “The following referenced documents are indispensab

36、le 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 titles, to which reference is made in the text. BS

If there is insufficient space on a line: use notes; repeat the line(s). Complete the relevant lines with the pertinent requirements, according to 4.5.2 to 4.5.24. Requir

38、ements (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 referenced on line 5, shall not be

39、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, 12, 19, 21, 23 and 25 shall be

40、 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 ISO 80000-1, ISO 80000-2, ISO 80000

41、-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 designation, in accordance with EN 2032-

42、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. The third line of boxes shall in

43、dicate the maximum content of that element. BS EN 4500-001:2012EN 4500-001:2012 (E) 9 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 elements, impurities, b

44、ase 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 means of a hyphen

45、. 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 observed for the v

46、alue 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/or maximum value

47、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 required. Modification

48、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 lines 12 to 99

49、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 terms as specified in the title. 4.5.6 Page 4, line 4.2: Method of production The method or methods of production shall be ind
