         Scope  of this standard  
 
ARTICLE 2 – (1) This standard specifies the set of minimum  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 spring s as a function of stress.  
 
                        (2) This standard covers three dimensional series of disc springs.  
 
                         (3) 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.
