CEN/TC 407 Cylindrical helical springs made from round wire and bar - Calculation and design
European Norm
21.160 Springs
Published
This standard specifies the set of requirements that ensure the correct functioning of disc spring. These include requirements relating to the materials and manufacturing process, tolerances on dimensions and spring forces, and also the permissible relaxation and fatigue life of such springs as a function of stress.
All requirements specified here are minimum requirements.
This standard covers three dimensional series of disc springs.
NOTE In this standard, disc springs are divided into three groups and three dimensional series. Classification into groups is based on the manufacturing process, which is a function of the material thickness. The assignment of disc springs to dimensional series is governed by the h0 /t ratio.
