BS EN 13906-1:2013

This standard BS EN 13906-1:2013 Cylindrical helical springs made from round wire and bar. Calculation and design is classified in these ICS categories:

• 21.160 Springs

This European Standard specifies 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 with values according to Table 1, and in respect of which the principal loading is applied in the direction of the spring axis.

Table 1

Characteristic	Cold coiled compression spring	Hot coiled compression spring
Wire or bar diameter	d ≤ 20 mm	8 mm ≤ d ≤ 100 mm
Number of active coils	n ≥ 2	n ≥ 3
Spring index	4 ≤ w ≤ 20	3 ≤ w ≤ 12
