Describes cylindrical helical compression springs made of round spring wire.

This European Standard applies to cylindrical helical compression springs made of round spring wire. Cold coiled compression springs can be made with wire up to about 16 mm diameter. (See also EN 13906-1). Cylindrical helical springs made of round wire from European Standard materials are subject to the limiting values in Table 1: Table 1 Characteristic Cold coiled compression springs Wire diameter 0,07 mm ≤ d ≤ 16 mm Mean coil diameter 0,63 mm ≤ D ≤ 200 mm Length of unloaded spring Lo ≤ 630 mm Number of active coils n ≥ 2 Spring index 4 ≤ w ≤ 20 A specification for the parameters of cold formed helical compression springs is given in Annex B.
