Guidance Criteria for Non-destructive Tests Not Required by Class
摘要
In the course of new construction or after various periods of service, an owner or shipyard, on their own initiative, may conduct radiographic or ultrasonic inspections of welds in addition to those specified in this chapter or required by the Surveyor. Although such inspections of welds are not required by Class, there are circumstances under which guidance is desired as to appropriate acceptance criteria. In some instances, the guidance in the table below indicates criteria that have been used by some shipyards and owners.
