These tubes are supplied in straight lengths in the hard or half-hard tempers, or in coils in the annealed temper. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies including amendments. EN 1655, Copper and copper alloys Declarations of conity.

NOTE Although the material symbol designation used in this standard might be the same as that 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 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 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 copper tube; number of this European Standard EN 12735-1; temper designation see Table 1; nominal cross-sectional dimensions outside diameter wall thickness see Table 2. The derivation of a product designation is shown in the following example.
