DIN EN 13906-1:2013-11

The revision of the EN 13906 series has been initiated by the Association of the European Spring Federation ESF in order to correct the technical errors which are in the published standards and to improve them according to the state of the art. However, the revision of the figures is not part of this work. This is due to the lack of shared (mutual) data to update them. Nevertheless, the purchasers/customers can have updated data from the manufacturers. This European Standard applies to the calculation and design of cold and hot coiled cylindrical helical compression springs with a linear characteristic, made from round wire and bar of constant diameter and in respect of which the principal loading is applied in the direction of the spring axis. For use of this standard the characteristics listed below are decisive. For cold coiled compression springs: - wire or bar diameter; d ≤ 20 mm - number of active coils; n ≥ 2 - spring index; 4 ≤ w ≤ 12 This document (EN 13906-1:2013) has been prepared by Technical Committee CEN/TC 407 "Project Committee - Cylindrical helical springs made from round wire and bar - Calculation and design", the secretariat of which is held by AFNOR (France). The responsible national mirror committee is NA 026-00-01 AA "Federn" ("Springs") of the standards committee springs, stamped parts and moulded parts (NAFS) at DIN e. V., the German Institute for Standardization. For further information about the NAFS, visit us on the internet under www.nafs.din.de.
