Profile EN 12167 — CW624N — M — S123 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 (profile or bar); c) number of this European Standard (EN 12167); d) material designation (see Tables 1 to 7); e) for bar, the 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) size and shape required: 1) for profiles, by fully dimensioned and toleranced drawing, which shall include any specific requirements for straightness and twist and, if appropriate, for flatness; SIST EN 12167:2016

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 6.2.1 Profiles Mechanical properties of profiles depend on the shape, dimensions and the material. For this reason, mechanical properties of profiles are not specified in this standard but, if needed, are subject to agreement between the purchaser and the supplier [see Clause 5, list entry k)]. 6.2.2 Bar Bar in the R. or H. condition shall conform to the appropriate tensile or hardness 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), CuZn36Pb2As (CW602N), CuZn32Pb2AsFeSi (CW709R), CuZn21Si3P (CW724R) and CuZn33Pb1AlSiAs (CW725R) products shall be 100 µm. For the alloys CuZn35Pb1,5AlAs (CW625N), CuZn33Pb1,5AlAs (CW626N) the maximum depth of dezincification, in any direction, shall be 200 µm. The test shall be carried out in accordance with 8.4. NOTE Shape and distribution of beta phase aggregates can influence the dezincification resistance of products. Special requirements relating to shape and distribution of ß phase aggregates are subject to agreement between purchaser and supplier. Products in alloys other than CuZn21Si3P (CW724R) shall be subjected to heat treatment approximately in the range 500 °C to 550 °C. Should the user need to heat the material above 530 °C (i.e. soldering, brazing or welding operations) then advice should be sought from the supplier. SIST EN 12167:2016

The tolerances given in Table 15 and 16 are applicable to the profiles within a circumscribing circle with a maximum diameter of 180 mm. 6.5.1.3 Bar The width and thickness of bar shall conform to the tolerances given in Table 17 for the appropriate alloy and tolerance class [see Clause 5 list entry g)]. 6.5.2 Length 6.5.2.1 Profiles The length of the profiles shall conform to the tolerances specified by the purchaser [see Clause 5 list entry h)]. 6.5.2.2 Bar The length of bar shall conform to the tolerances given in Table 18. Subject to agreement between the purchaser and the supplier, an agreed proportion of underlength profiles or bar may be included in a consignment. 6.5.3 Flatness 6.5.3.1 Profiles If appropriate, the maximum deviation from flatness shall be agreed between the purchaser and the supplier and stated on the order/drawing [see Clause 5 list entry g)]. 6.5.3.2 Bar The maximum deviation from flatness (“e” in Figure 1) of bar (thickness a, width b) is dependent on the tolerance class [see Clause 5 list entry g)] and shall be: — Class A: 0,4 mm; SIST EN 12167:2016

Figure 1 — Measurement of flatness of bar 6.5.4 Straightness 6.5.4.1 Profiles The tolerance on straightness shall be agreed between the purchaser and the supplier and stated on the order/drawing, [see Clause 5 list entry g)]. 6.5.4.2 Bar For widths 10 mm and over, and lengths 1 000 mm and over, the deviation from straightness, defined as the curvature (depth of arc) against a datum line when the product is lying flat in a horizontal plane, shall conform to the tolerances given in Table 19 for the appropriate tolerance class [see Clause 5 list entry g)]. 6.5.5 Twist 6.5.5.1 Profiles The tolerance on twist shall be agreed between the purchaser and the supplier and stated on the order/drawing [see Clause 5 list entry g)]. 6.5.5.2 Bar The maximum permitted twist V (see Figure 2) of bar (thickness a, width b), as measured between two cross-sections along the bar, shall conform to Table 20 for the appropriate tolerance class [see Clause 5 list entry g)].

If a purchaser requires the corners to have larger radii than those specified in Table 21, then the product is effectively a profile and the dimensions and tolerances of the corner radii required should be stated on the order/drawing. Except in cases of dispute, the corners should be measured directly, either by use of a gauge or an optical projector. In cases of dispute, the method by optical projector should be used. 6.6 Surface quality The surfaces shall be clean and smooth. The profiles and bars 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 profiles and bars 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 l)]. SIST EN 12167:2016
