This International Standard applies to the inspection of isotropic graphite ingots for use in solid rocket motors with the purpose of detection of planar flaws that orient in various directions, using immersion testing of a single probe, pulse echo ultrasonic method. Test blocks are in a cylindrical form having a diameter/height ratio of approximately one and a diameter and height within 225 mm. Prior to inspection, the size, position and direction of the permissible flaw shall be evaluated in the design procedure. The minimum equivalent flaw diameter to be detected shall be set larger than 3 mm.
