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 12164); d) material designation (see Tables 2 to 7); e) material condition designation (see 4.2 and Tables 8 to 13) 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) for round rod up to and including 30 mm diameter, whether Class A or Class B tolerances are required, unless the tolerance class shall be left to the discretion of the supplier (see Table 14); j) for rod with square, hexagonal and octagonal cross-section, whether “sharp” or “rounded” corners are required unless the corner radii of the rod shall be left to the discretion of the supplier (see 6.5.5 and Table 18); SIST EN 12164:2016

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 13. The tests shall be carried out in accordance with 8.2 or 8.3. SIST EN 12164:2016
