Cylindrical helical springs made from round wire and bar. Guide to methods of specifying and tolerancing hot coiled springs, and cold coiled springs not covered by BS EN 15800, and general spring testing. Compression springs
This part of BS 1726 provides guidance on methods of specifying and
tolerancing hot coiled compression springs, and cold coiled springs that
fall outside the size range limits specified in BS EN 15800. In addition,
this standard includes in Annex A the general testing methods for
parallel sided helical compression springs that are applicable to both
hot and cold coiled springs manufactured from circular section material.
Two grades of tolerance, 1 and 2, are given for hot coiled circular
section springs, or cold coiled springs that fall outside the size ranges
specified in BS EN 15800.
Three types of end coils are provided for, i.e. open end, closed end,
and closed and ground end, the last of these being applicable only to
springs where the diameter or axial dimension of material is 0.5 mm
or greater.
This part of BS 1726 differentiates between springs that have or have
not been stress relieved after forming (designated group A), and
springs, the material of which has undergone a structural change by
heat treatment after forming (designated group B).
This standard gives two methods of specifying springs for general
purposes and one method of testing springs.
