IS 12511 : Part 2 : 2004 Springs - Disc Spring - Part 2 : Specification

1 Scope

1.1 This standard (Part 2) specifies requirements for the materials,dimensions, tolerances, and permissible stresses for conical disc springs.It includes graphs showing the permissible relaxation and the endurancelife of such springs, as a function of stress.

1.2 The values specified in this standard apply to operating temperaturesbetween 0 and 60�C.

1.3 The minimum requirements specified are intended to ensure the properperformance of conical disc springs and may also be applied tonon-standardized springs.

1.4 The three series specified here represent groups of spring sizes whichhave met with general acceptance in practice.
