All costcast pressure-retaining parts of a size and configuration for which 123 124 volumetric examination methods are effective shall be examined by radiographic methods by qualified personnel. Ultrasonic examination to equivalent standards may be used as alternate to radiographic methods. 2b. Examination procedures and acceptance standards shall be at least equivalent to those specified as supplementary types of examination in ANSI B31.1-1973, Par. 136.4.125 The following qualification shall be met with respect to the certification requirements: 2 DRAFT Rev. 2 - April 1996 3.2.2-16 1a.
