A rupture disk (20), along with associated methods, is disclosed. More particularly, a miniaturized rupture disk is disclosed, comprising a transition area (23) configured to determine a pressure at which the rupture able portion will rupture. A method for forming a rupture disk is also disclosed, wherein a radius (R) of a transition area is configured to set the burst pressure of the rupture disk. A rupture disk having an indent at its apex (24) and a circular line of weakness configured to improve opening performance is also disclosed. Additionally, a method of relieving pressure in a pressurized system is disclosed, wherein a set of rupture disks is provided, wherein each rupture disk in the set has a different radius of transition area. A rupture disk may be selected from the set and installed based on a burst pressure set by the radius of transition area.
