1. An improved method of manufacturing a group of scored reverse buckling rupture disks of desired reversal rupture pressure from sheet metal comprising the steps of:

  • (a) dividing said sheet metal into a plurality of sections;

    (b) forming a concave-convex dome in each of said sheet metal sections; and

    (c) forming identical scores of predetermined depth on a surface of each of said concave-convex dome portions of said sheet metal sections thereby creating identical lines of weakness therein, said scores radiating outwardly and having a greater depth, at the central portions of the radii of said concave-convex dome.
