35、ve references to documents used in the preparation of this standard, and cited at the appropriate places in the text, are listed in a bibliography, see annex A. 3 Definitions For the purposes of this standard, the following definitions apply. 3.1 profile wrought product of uniform cross-section alon
36、g its whole length, with a cross-section other than rod, hollow rod, bar, rectangle, tube, sheet or strip, supplied in straight lengths 3.2 rectangular bar wrought product of uniform rectangular cross-section along its whole length, supplied in straight lengths 4 Designations 4.1 Material 4.1.1 Gene
37、ral The material is designated either by symbol or number (see Tables 1 to 8). 4.1.2 Symbol The material symbol designation is based on the designation system given in ISO 1190-1. NOTEAlthough material symbol designations used in this standard might be the same as those in other standards using the
38、designation system given in ISO 1190-1, the detailed composition requirements are not necessarily the same. 4.1.3 Number The material number designation is in accordance with the system given in EN 1412. 4.2 Material condition For the purposes of this standard, the following designations, which are
39、in accordance with the system given in EN 1173, apply for the material condition. MMaterial condition for the product as manufactured, without specified mechanical properties. R.Material condition designated by the minimum value of tensile strength requirement for the product with mandatory tensile
40、strength requirement. H.Material condition designated by the minimum value of hardness requirement for the product with mandatory hardness requirement. NOTE 1Products in the H. condition may be specified to Brinell or Vickers hardness. The material condition designation H. is the same for both hardn
41、ess test methods. S (suffix)Material condition for a product which is stress relieved. NOTE 2Products in the M, R. or H. condition may be specially processed (i.e. mechanically or thermally stress relieved) in order to lower the residual stress level to improve the resistance to stress corrosion and
42、 the dimensional stability on machining see 5j), 5k) and 8.5. Page 5 EN 12167:1998 BSI 1998 Exact conversion between material conditions designated R. and H. is not possible. Except when the suffix S is used, material condition is designated by only one of the above designations. 4.3 Product The pro
43、duct designation provides a standardized pattern of designation from which a rapid and unequivocal description of a product is conveyed in communication. It provides mutual comprehension at the international level with regard to products which meet the requirements of the relevant European Standard.
44、 The product designation is no substitute for the full content of the standard. The product designation for products to this standard shall consist of: denomination (profile or rectangular bar); number of this European Standard (EN 12167); material designation, either symbol or number (see Tables 1
45、to 8); material condition designation (see Tables 9 to 16); for profiles, the number of the profile or a fully dimensioned and toleranced drawing; for rectangular bar, the nominal cross-sectional dimensions; for rectangular bar, the tolerance class (see Table 17); for rectangular bar, the corner typ
46、e (the following designations shall be used as appropriate: SH for sharp, RD for rounded) (see Table 21). The derivation of a product designation is shown in example 1 and another typical product designation is shown in example 2. EXAMPLE 1 Rectangular bar conforming to this standard, in material de
