24、ts Elements other than base metal, for which the mass content gives the typical characteristics of the alloy. 3.2 The 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-tr

25、eated in accordance with the material standard. Limit dimension and equivalent diameter De 4 Rules for drafting and presentation 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. Techn

26、ological development may require the use of terms additional to those listed. 4.1 Page 1 : Title of the material standard The title shall give sufficient information to unambiguously identify the semi-finished product, in the use condition (see 4.4.1 O). Consequently : 1. the same title shall not be

27、 used for different material standards ; 2. overlapping of mechanical property limits for otherwise identical material standards shall not normally be permitted. Each part of the title shall consist of one or several different lines : - aerospace series ; - the family of metallic material, followed

28、by the designation of the metallic material in accordance with EN 2032-1 ; - method of melting, if appropriate ; - 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 u

29、se ; - limiting dimensions ; - relevant mechanical property or physical property limits, if appropriate. 4.2 Page 2 Blank, in principle.

35、orresponds to form 1 given in annex A If there is insufficient space on a line: - use notes ; - repeat the line(s). Complete the relevant lines with the pertinent requirements, according to 4.4.1 to 4.4.23. Requirements (test method, frequency of testing, sample type, test piece definition, heat tre

36、atment 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 repeated, in this case writte “See EN XXXX“. If it is necessary to modify the requireme

37、nts 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 preceded by a sign depending on whether they are minimum or maximum values (, I, 2).

38、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 IS0 31-0, IS0 31-1, IS0 31-3,ISO 31-4, IS0 31-9, IS0 31-1 1 and IS0 1000. Specific examples are given for each f

41、ll be written in the first line of boxes, in accordance with established conventions (see IS0 31 -9). Page 4, line 2 : Chemical composition The second line of boxes shall indicate the minimum content of that element. The third line of boxes shall indicate the maximum content of that element. The mas

42、s 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, base metal for filler metals, etc) shall only be specified by a minimum and/or a maximum value

43、, 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. Ratio and/or total content of two or more elements may be specified on line 2. All values V

44、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 value V : - V min. or V max, I0,Ol % - V min. 0,Ol % express V minrn and V max. in “p.p.m.“ ; e

45、xpress 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 or by the expression “base“. The standard order for presentation of the elemen

46、ts for each family of metallic materials is specified in EN 4500-2 to EN 4500-6. 4.4.3 Line 3 shall be completed with the appropriate information when one or several specific methods of melting are required. Page 4, line 3 : Method of melting Modification to line 3 (by addition of further melting me

47、thods or changes to melting methods) cannot include a change of the EN reference number if the requirements defined in lines 12 to 98 do not change. When several methods of melting can be used under the same EN reference (.e. the requirements in the lines 12 to 98 do not change), line 3 shall contai

48、n a note which will state in line 98 ; “the melting route for qualification and subsequent delivery of products shall be identical“. 4.4.4 The form or similar forms of the products covered by the standard shall be stated using the same terms as specified in the title.
