ASME PCC-3 guides the preparation and implementation of a risk-based inspection plan. Flaws identified during inspection plan implementation are then evaluated, when appropriate, using the procedures provided in API 579-1/ASME FFS-1, Fitness-for-Service. If it is determined that repairs are required, guidance on repair procedures is provided in ASME PCC-2, Repair of Pressure Equipment and Piping.
This Standard is based on API 580, Risk-Based Inspection. By agreement with the American Petroleum Institute, this Standard is closely aligned with the RBI process in API 580, which is oriented toward the hydrocarbon and chemical process industries. In the standards development process that led to the publication of this Standard, numerous changes, additions, and improvements to the text of API 580 were made, many of which are intended to generalize the RBI process to enhance applicability to a broader spectrum of industries.
This Standard provides recognized and generally accepted good practices that may be used in conjunction with Post-Construction Codes, such as API 510, API 570, and NB-23.
