IS 7906 : Part 1 : 1997 Helical Compression Springs - Part 1 : Design and Calculations for Springs Made from Circular Section Wire and Bar

1 Scope

1.1 This standard (Part 1) lays down calculations for design ofhelical compression springs made from circular section wire andbar.

1.2 It applies to cold and hot coiled Compression springs whichhave working coils with uniform pitch over the working length, areloaded in the direction of the spring axis and work at ordinaryroom temperature. For operations at considerably higher or lowertemperature, reference should be made to the spring manufacturer.
