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) mass of product required; b) denomination (Rod); c) number of this European Standard (EN 12163); d) material designation (see Tables 1 to 7); e) material condition designation (see 4.2 and Tables 8 to 14) if it is other than M; f) DW for compliance in the chemical composition according to the 4 MS Common Composition List. This information is mandatory in the case in which the product is used for drinking water applications according to the 4 MS Common Composition List and not to be given in other cases; g) cross-sectional shape; h) nominal cross-sectional dimension (diameter or width across-flats); i) whether other than class A tolerances are required (see Table 15); j) for polygonal rod: whether “sharp” or “rounded” corners are required unless the corner radii shall be left to the discretion of the supplier (see 6.5.5 and Table 17); SIST EN 12163:2016

Due to developing legislation, specific applications (see 4.3) may require restrictions in the chemical composition. In this case the limitations shall be specified in the ordering information [see Clause 5, list entry f)]. 6.2 Mechanical properties The tensile or the hardness properties shall conform to the appropriate requirements given in Tables 8 to 14. The tests shall be carried out in accordance with 8.2 or 8.3. 6.3 Resistance to dezincification The maximum depth of dezincification, in any direction, of CuZn38As (CW511L) and CuZn21Si3P (CW724R)) products shall be 100 µm. The test shall be carried out in accordance with 8.4. SIST EN 12163:2016

Key 1 reference plane V twist W width across-flats Figure 1 — Measurement of twist of polygonal rod 6.6 Surface quality The surfaces shall be clean and smooth. The rods may have a superficial film of drawing lubricant or, if annealed or thermally stress relieved, a superficial, dull, iridescent oxide film, securely adherent on the surfaces. Discontinuous irregularities on the surfaces of the rods are permitted if they are within the dimensional tolerances. Special requirements (e.g. pickling, degreasing, etc.) relating to the surface quality shall be agreed between the purchaser and the supplier [see Clause 5, list entry n)]. 7 Sampling 7.1 General When required (e.g. if necessary in accordance with specified procedures of a supplier's quality system, or when the purchaser requests inspection documents with test results, or for use in cases of dispute), an inspection lot shall be sampled in accordance with 7.2 to 7.4. 7.2 Analysis The sampling rate shall be in accordance with Table 19. A test sample, depending on the analytical technique to be employed, shall be prepared from each sampling unit and used for the determination of the composition. SIST EN 12163:2016
