This Part of BS 1726 provides guidance on the specification, tolerancing and testing of parallel sided helical compression springs manufactured from round wire and bar.
Two grades of tolerance, 1 and 2, are given for springs.
Fifteen types of end coils are provided for, these being divided into three groups.
This standard applies to springs which have not been subjected to heat treatment other than stress relieving after coiling.
This standard gives two methods of specifying springs and a methods of testing springs.
