1   Scope

This European Standard specifies the calculation and design of cold and hot coiled cylindrical helical torsion springs with a linear characteristic, made from round wire and bar of constant diameter with values according to Table 1.
Table 1
Characteristic Cold coiled torsion spring Hot coiled torsion springa
Wire or bar diameter d ≤ 20 mm d ≥ 10 mm
Number of active coils n ≥ 2 n ≥ 2
Spring index 4 ≤ w ≤ 20 4 ≤ w ≤ 12
a The user of this European Standard shall pay attention to the design of hot coiled springs, because there can be differences between the design and a real test.
