hollow semi-finished product, circular in cross-section, having a uniform wall thickness, which at all
stages of production has a continuous periphery
3.2

4 Designations
4.1 Material
4.1.1 General
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.
NOTE Although material symbol designations used in this standard might be the same as those in other
standards using the 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 in accordance with the system
given in EN 1173, apply for the material condition:
M material 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 property requirements;
H. material condition designated by the minimum value of hardness requirement for the product
with mandatory hardness requirements.

SIST EN 12449:2016+A1:2019
EN 12449:2016+A1:2019 (E)
NOTE 1 Products in the H. condition can be specified to Vickers or Brinell hardness. The material condition
designation H. is the same for both hardness test methods.
S (suffix) material condition for a product which is stress relieved.
NOTE 2 Products in the M, R. or H. condition can 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 (see 6.5.2).
Exact conversion between the 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 product 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.
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 (Tube);
— number of this European Standard (EN 12449);
— material designation, either symbol or number (see Tables 1 to 8);
— material condition designation (see Tables 9 to 15);
— nominal cross-sectional dimensions, either outside diameter (OD) and wall thickness or inside
diameter (ID) and wall thickness (see 6.3).
The derivation of a product designation is shown in Example 1.
EXAMPLE 1 Tube conforming to this standard, in material designated either CuNi10Fe1Mn or CW352H, in
material condition H075, nominal outside diameter 22 mm, nominal wall thickness 2,0 mm, will be designated as
follows:
Tube EN 12449 — CuNi10Fe1Mn — H075 — OD22 × 2,0
