Scope

This document describes the measurement and testing methods for the general characteristic parameters of cold-formed cylindrical helical torsion springs except for dynamic tests.
This document is applicable to cold-formed cylindrical helical torsion springs that do not undergo quenching and tempering (such as tangential torsion arm torsion springs and radial outer torsion arm torsion springs, parallel double torsion springs). The parameters of cold-formed cylindrical helical torsion springs with other cross-sections can be used for reference.
