5 Information to be supplied by the purchaser The purchaser shall clearly state in his enquiry or order the product and following information: a) the desired quantity; b) the term spring steel wire or straightened and cut lengths; c) the number of this European standard: EN 10270-1; d) the steel grade (see Tables 1 and 2); e) the nominal wire diameter selected from Table 3 and for cut length the length and the length tolerance class (see Table 7); f) the coating indicated by its abbreviation and surface finish (see 6.3); g) the form of delivery and unit mass (see 6.2); h) the type of inspection document !(see 7.1)"; i) any particular agreement. SIST EN 10270-1:2012+A1:2017

Table 2 — Chemical composition, % by mass Grade Ca Si Mnb P S Cu SL, SM, SH 0,35 to 1,00 0,10 to 0,30 0,40 to 1,20 0,035 max. 0,035 max. 0,20 max.

For individual sizes the carbon range is substantially more restricted. b For the manganese content, a different range from the one indicated in the table may be agreed at the time of ordering, with a maximum not exceeding 1,20 % and with a minimum range of 0,20 %.
" The addition of micro-alloying elements may be agreed between the manufacturer and the purchaser. NOTE Some diameter ranges require particular attention for residuals. Therefore no figures are mentioned for chromium, nickel, molybdenum, tin, etc., leaving room for special arrangements between Purchaser and Supplier, dependent on their mutual processing conditions. This is also the case for the aluminium content. 6.2 Form of delivery The wire shall be delivered in unit packages of a coil (singles, carriers or formers), spools, spoolless cores or as straight lengths. Unless otherwise agreed at the time of ordering, the form of delivery will be coils; straight lengths shall be supplied in bundles. SIST EN 10270-1:2012+A1:2017
