请注意，本标准的翻译版本中可能不包括任何附录或勘误表。本推荐规程描述了可用于“证明”缺陷深度或尺寸的程序。本规程包括使用振幅比较技术和振幅距离差分技术对新管道进行超声波验证检查的推荐程序，用于评估1）管道主体中的表面断裂缺陷和2）电阻焊接区域中的表面断裂和亚表面缺陷，电感应或激光焊接管道和3）电弧焊接管道焊接区域的表面断裂和亚表面缺陷。

Please note that any addenda or errata may not be included in translated editions of this standard.This recommended practice describes procedures which may be used to "prove-up" the depth or size of imperfections.Included in this practice are the recommended procedures for ultrasonic prove-up inspection of new pipe using the Amplitude Comparison Technique and the Amplitude-Distance Differential Technique for evaluation of 1) surface breaking imperfections in the body of pipe and 2) surface breaking and subsurface imperfections in the weld area of electric resistance, electric induction or laser welded pipe and 3) surface breaking and subsurface imperfections in the weld area of arc welded pipe.
