This part of BS1726 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 BSEN15800. 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 BSEN15800.
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 0.5mm or greater.
This part of BS1726 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.
