The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Technical Committee (TC) in CEN is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
This European Standard applies to cylindrical helical compression springs made of round spring wire. Cold coiled compression springs can be made with wire up to about 16 mm diameter. (See also EN 13906-1).
NOTE For springs with wire diameter upper 16 mm up to 20 mm see Annex A
Cylindrical helical springs made of round wire from European Standard materials are subject to the limiting values in Table 1 (see also Annex A):
Table 1
Characteristic Cold coiled compression springs
Wire diameter 0,07 mm ≤ d ≤ 16 mm
Mean coil diameter 0,63 mm ≤ D ≤ 200 mm
Length of unloaded spring Lo ≤ 630 mm
Number of active coils n 2
Spring index 4 ≤w ≤ 20
A specification for the parameters of cold formed helical compression springs is given in Annex B.
