Gives guidance on the specification, tolerancing and testing of parallel sided helical torsion springs manufactured from round wire and bar. It defines two methods of specifying springs for general purposes and one method of testing springs.

This Part of BS1726 provides guidance on the specification, tolerancing and testing of parallel sided helical torsion springs manufactured from round wire and bar.

It applies to springs which may or may not be stress relieved after forming (hereinafter referred to as group A springs) and to springs the material of which has undergone a structural change by heat treatment after forming (hereinafter referred to as group B springs).

This standard gives two methods of specifying springs for general purposes and one method of testing springs.

NOTE It is not recommended that torsion springs be loaded in the opposite direction to that of coiling. If this is necessary then discussions should take place between purchaser and supplier.
