- Scope
- This standard specifies the replication and microscopic measurement methods of the size of artificial defects (artificial grooves/through holes) in comparison samples for zirconium tube flaw detection. This standard is suitable for measuring the size of artificial grooves/through holes on zirconium tube ultrasonic, eddy current and other non-destructive testing comparison samples. The measurement of similar artificial defect sizes in other metal comparison samples can also be performed with reference.
