24、one series of characters (letters, figures, dashes) all metallic materials having the same basic chemical composition without taking into account: any option concerning other elements than alloying elements, the method of melting, the heat treatment, the form. NOTE The method of melting may induce v
25、ariations in the mass content of one or several alloying elements. These variations are not considered significant and shall not be taken into consideration. 4.2 ASD-STAN designation ASD-STAN designation is not applicable to new standard and revision for: nickel base or cobalt base alloys (see 5.2,
26、EN 10027-1 and EN 10027-2), steels (see 5.4, EN 10027-1 and EN 10027-2), commercially pure titanium and titanium base alloys (see 5.5). The ASD-STAN designation of each material comprises nine characters divided into three groups: A group of three characters consisting of: the symbol of the base met
27、al in accordance with ISO 80000-9, but written entirely in capital letters, dash(es) for completion to three characters. A group of five characters: the first three characters indicate the alloying elements (one, two or three) considered significant (with the exception of all aluminium base material
28、s). If the chemical composition is such that there is only one or two alloying elements, the remaining character(s) is (are) a zero. The use of this group of three characters is defined in each of the relevant following clauses. In addition, one character indicates the method of production for struc
29、tural materials or the use for joining materials (see 4.3). the last two of this group of five characters (or the last character in the case of cast aluminium base alloys, see 5.3.2) form a serial number starting at 01 (or 1 in the case of cast aluminium base alloys, see 5.3.2). This serial number s
30、hall be changed every time the first three and the last five characters already allocated do not fit the new basic chemical composition to be designated. The conventional designation is unique for one basic chemical composition, except for certain filler metals for brazing (see 6.2.2.2 and 6.2.2.3).
31、 prEN 2032-001:2011 (E) 7 4.3 Method of production or use A capital letter from the following series: Structural material - C for cast material, P for cast + wrought material, R for powder metallurgy material, Joining material - W for welding material, B for brazing material. 4.4 Basic chemical comp
32、osition (base metal excluded) A group of five digits: 4.4.1 In the case of unalloyed materials, the first three digits indicate information as in 5.1. 4.4.2 In the case of metallic alloys, with the exception of all aluminium base materials (see 5.3), the first three digits indicate the alloying elem
33、ents (one, two or three) considered significant (see 5.1, 5.2, Annex B, Annex C, Annex D and 5.6 to 6.2). If the chemical composition is such that there is only one or two alloying elements, the remaining digit(s) is (are) a zero. The use of this group of three digits is defined in each of the relev
34、ant following clauses. 4.4.3 The last two of this group of five digits form a serial number starting at 01. This serial number shall be changed every time the first three and the last five digits already allocated do not fit the new basic chemical composition to be designated. NOTE In consequence of
35、 4.1, 4.2 and 4.3, except for certain brazing materials (see 6.2.2.1 and 6.2.2.2) the first three and the last five digits correspond to one and only one basic chemical composition, whatever the letter used as the fourth digit. 4.5 Mass content of an alloying element It shall be taken as the arithme
36、tical mean of the limits of its range. If two alloying elements have the same mass content, they shall be written according to the alphabetical order of their international symbol. 5 Structural materials 5.1 Unalloyed metals With the exception of all aluminium base materials (see 5.3), the group of
37、five digits of the designation comprises from left to right: a single capital letter U symbolic of this category, a number indicating the percentage of base metal after the decimal point, completed with zero if necessary, last two digits as serial numbers (This serial number shall be changed every t
38、ime the first three and the last five characters already allocated do not fit the new basic chemical composition to be designated). prEN 2032-001:2011 (E) 8 EXAMPLE Cast wrought copper 99,97 % pure CU-PU9701 Copper Cast wrought material Unalloyed Number indicating the percentage of base metal after
