卫生及供暖应用中用于水和气体的无缝圆形铜管

4.1.2 Symbol

The material symbol designation is based on the designation system given in ISO 1190-1.

4.1.3 Number

The material number designation is in accordance with the system given in EN 1412.

4.2 Material temper

For the purposes of this standard, the following designation, which is in accordance with the system given in EN 1173, applies for the material temper (see table 1):

R... Temper designated by the minimum value of tensile strength requirement for the product with mandatory tensile strength and elongation requirements.

4.3 Product

Product designation provides a standardized system for the rapid and unambiguous description and identification of a product. It provides a means of mutual comprehension at the international level with regard to products which meet the requirements specified in the relevant European Standard.

It goes without saying that the product designation is no substitute for all the information contained in a standard. The product designation shall consist of the following:

• term (copper tube);
• number of this European Standard (EN 1057);
• material temper (see table 1);
• nominal cross sectional dimensions, in millimetres: outside diameter × wall thickness.

EXAMPLE:

Copper tube conforming to this standard, temper R220 (annealed), of nominal outside diameter 12 mm and nominal wall thickness 1,0 mm, shall be designated as follows:

Copper tube EN 1057 – R220 – 12 × 1,0

Term

Number of this European Standard

Temper designation

Nominal cross-sectional dimensions, in millimetres

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 order the following information:

• a) quantity of material required (in metres);
• b) term (copper tube);
• c) number of this European Standard (EN 1057);
• d) temper designation (see 4.2 and table 1);
• e) nominal cross-sectional dimensions: outside diameter × wall thickness (see table 3 and annex A);
• f) length (see 9.2);
• g) form of supply (see 9.2).

NOTE: It is recommended that the product designation as described in 4.3 be used for items b) to e).

EXAMPLE:

Ordering details for 500 m copper tube conforming to EN 1057, in temper R220 (annealed), of nominal outside diameter 12 mm and nominal wall thickness 1,0 mm, in 50 m coils:

500 m copper tube EN 1057 – R220 – 12 × 1,0 – 50 m coils

6 Requirements

6.1 Composition

The composition shall conform to the following requirements:

Cu + Ag: min. 99,90 %.

0,015 % ≤ P ≤ 0,040 %.

This copper grade is designated either Cu-DHP or CW024A.

6.2 Mechanical properties

The tensile strength and elongation shall conform to the requirements given in table 1. Testing shall be carried out in accordance with 8.2.

Table 1: Mechanical properties

Material temper Designation as in EN 1173	Common term	Minimum	Maximum	Minimum tensile strength, Rm, in MPa	Minimum elongation, A, as a percentage	Hardness HV 5 (indicative)
R220	Annealed	6	54	220	40	(40 to 70)

1) See table 2 for relationship between tube dimensions and elongation for R250 temper tubes.

NOTE 1: Hardness values given in parentheses are no requirements but are for guidance only.

NOTE 2: 1 MPa is equivalent to 1 N/mm².
