4.2 Material condition
For the purposes of this document, the following designations, which are in accordance with the system given in EN 1173, apply for the material condition:
D Material condition for the product as cold worked without specified mechanical properties;
H… Material condition designated by the minimum value of hardness requirement for the product with mandatory hardness requirements;
R… Material condition designated by the minimum value of tensile strength requirement for the product with mandatory tensile strength, 0,2 % proof strength and elongation requirements. Products in the H… condition may be specified to Vickers or Brinell hardness. The material condition designationH… is the same for both hardness test methods. Exact conversion between the material conditions designated H… and R… is not possible. Material condition is designated by only one of the above designations.
4.3 Product
The product designation provides a standardized pattern of designation from which a rapid and unequivocal description of a product can be conveyed in communication. It provides mutual comprehension at the international level with regard to products which meet the requirements of the relevant European Standard. The product designation is no substitute for the full content of the standard.
The product designation for products to this document shall consist of:
a) denomination (rod, bar or wire);
b) number of this document (EN 13601);
c) material designation, either symbol or number (see Table 1 and Table 2); d) material condition designation (see Table 3);
e) cross-sectional shape (the following designations shall be used as appropriate: RND for round, SQR for square, HEX for hexagonal);
f) nominal cross-sectional dimensions:
1) round rod or wire: diameter;
2) square or hexagonal rod or wire: width across-flats;
3) bar or rectangular wire: thickness × width;
g) tolerance class for round, square or hexagonal rod or wire (see Table 5);
h) corner type for square or hexagonal rod, bar or rectangular wire (the following designations shall be used as appropriate: SH for sharp, RD for rounded, CE for semi-circular edges) (see 6.6.2). The derivation of a product designation is shown in Example 1 and other typical product designations are shown in Example 2 and Example 3.
5 Ordering information
In order to facilitate the enquiry, order and confirmation of order procedures between the purchaser and the supplier, the purchaser shall state on his enquiry and order the following information:
a) quantity of product required (mass, number of rods or bars or coils of wire);
b) denomination (rod, bar or wire);
c) number of this document (EN 13601);
d) material designation (see Table 1 and Table 2);
e) material condition designation (see 4.2 and Table 3);
f) cross-sectional shape (round, square, hexagonal or rectangular);
g) nominal dimensions (diameter, width across-flats or thickness × width);
h) tolerance class for round, square or hexagonal rod or wire: either Class A (minus tolerance only) or Class B (plus/minus tolerance) (see Table 5);
i) type of corner (see 6.6.2);
j) for rod or bar, the length required (see 6.6.3);
k) for wire, the coil type: pancake, traverse wound, bunch or on drums (see 6.8);
l) coil size requirements: inside and/or outside diameter and width or mass.
It is recommended that the product designation, as described in 4.3, is used for b) to i).
In addition, the purchaser shall also state on the enquiry and order any of the following, if required:
m) test method to be used for measurement of hardness, i.e. Brinell or Vickers (see 8.3) unless the test method is to be left to the discretion of the supplier;
n) whether sawn or sheared ends are required (see 6.6.3);
o) whether special surface conditions are required (see 6.10);
p) whether a bend test is required (see 6.3);
q) whether form tolerances for wire are required (see 6.7.1);
r) whether length of wire is required (see 6.6.3);
s) whether sampling is required (see Clause 7);
t) whether a declaration of conformity is required (see 9.1);
u) whether an inspection document is required, and if so, which type (see 9.2);
v) whether there are any special requirements for marking, packaging or labelling (see Clause 10).
