EN 2032-1:2001 (E)54Principle4.1GeneralThe conventional designation defines by one series of characters (letters, figures, dashes) all metallicmaterials having the same basic chemical composition (see 4.2 and 4.4) without taking into account:–any option concerning other elements than alloying elements,–the method of melting;–the heat treatment;–the form.NOTEThe method of melting may induce variations in the mass content of one or several alloyingelements. These variations are not considered significant and shall not be taken into consideration.In addition, one character indicates the method of production for structural materials or the use for joiningmaterials (see 4.3).Regardless of this character, 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).The designation of each material comprises nine characters, divided into three groups, the contents of eachof them is as in 4.2 to 4.5.4.2Base metalA group of three characters consisting of:–the symbol of the base metal in accordance with ISO 31-8, but written entirely in capital letters,–dash(es) for completion to three characters.4.3Method of production or useA capital letter from the following series:Structural material -------Cfor cast material;Pfor cast + wrought material;Rfor powder metallurgy material;Joining material ----------Wfor filler metals for welding;Bfor filler metals for brazing.4.4Basic chemical composition (base metal excluded)A group of five characters:4.4.1In the case of unalloyed materials, the first three characters indicate information as in 5.1.4.4.2In the case of metallic alloys, with the exception of all aluminium base materials (see 5.3), the firstthree characters indicate the alloying elements (one, two or three) considered significant (see 5.1, 5.2 and 5.4to 6.2). If the chemical composition is such that there is only one or two alloying elements, the remainingcharacter(s) is (are) a zero.The use of this group of three characters is defined in each of the relevant following clauses.4.4.3The last two of this group of five characters (or the last character in the case of cast aluminiumbase 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 shall be changed every time the first three and the last five characters alreadyallocated do not fit the new basic chemical composition to be designated.SIST EN 2032-1:2004
