This International Standard specifies terms and definitions commonly used in the metal springs industry. Specifically, these terms appear in technical product documentation. Heat-treatment and surface-treatment terms pertinent to springs are included.
Terms are grouped into the following seven categories:
a) general features of springs;
b) application of springs in machinery and engineering;
c) layout and nomenclature of springs;
d) specification requirements;
e) design and calculation;
f) manufacturing and processing;
g) testing and inspection.
The hierarchical structure of terminology in each category is given in Annex B.
