The criteria outline specific length limits for imperfections based on the thickness of the 317 Practice for Evaluating Performance Characteristics of Ultrasonic Pulse-Echo Testing Instruments and Systems without the Use of Electronic Measurement Instruments 428 Practice for Fabrication and Control of Metal, Other than Aluminum Reference, Blocks Used in Ultrasonic Examination The document discusses acceptance criteria for various non-destructive testing methods according to ASME BPVC Section VIII Div 1, 2017 Edition, including: 1. An as acceptance ic testing corresponding as acceptance is generally not requested in ferritic level 2 (AL 2) and 5817:2014, correspond to y s docume The acceptance criteria for Ultrasonic Testing (UT) specify that indications such as cracks, lack of fusion, or incomplete penetration are unacceptable regardless of their length. Other imperfections must be below reference level amplitude and length thresholds. These criteria are essential guidelines that define permissible limits for detected flaws, defects, or anomalies during To accomplish this, qualified professionals, calibrated equipments / instruments, standard examination procedures and codified acceptance criteria are the sinequanon, where NDE assumes utmost importance. This is a sample UT procedure and may be required to be modified as per specific requirements. Amongst various NDE methods available for inspection, this paper highlights ASME Code requirements for ultrasonic examination. pdf), Text File (.
