- Scope
- This standard specifies the general principles of ultrasonic detection penetration technology. Penetration technology is used for: --- Defect detection; --- Attenuation determination. This standard is applicable to the detection of flat workpieces, such as: flat plates and strips, and is also applicable to the detection of: --- defects whose shape, size or direction are not conducive to direct reflection method detection; --- high attenuation materials; --- thin workpieces . The penetration technique stipulated in this standard focuses on the transmission attenuation technique based on the measurement of the signal attenuation degree after the ultrasound penetrates the object under test.
