- Scope
- This standard specifies the ultrasonic testing methods and results evaluation of alloy bearing bushes of turbine generators in service. This standard is applicable to the inspection during installation and maintenance of tin-based and lead-based alloy bearing bushes with a thickness of not less than 1mm. This standard is not applicable to the detection of the area within the radius of the probe from the edge of the bearing bush, oil hole and oil groove. If there is a dovetail groove on the bearing joint surface, it is not applicable to the detection of the area along the edge of the dovetail groove.
