GB/T 39241-2020 (英語版) 非破壊検査超音波検査浸透技術規格と仕様

範囲: 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.
