![]() API strongly encourages candidates to review these forms in preparation for the QUSE-PA exam: ![]() View the forms below that will be used during the exam.API-UT-11 - Defines the recommended methods and techniques for ultrasonic crack sizing.Please review all documentation below prior to exam day, which includes:.The candidate will be expected to size inside surface breaking cracks and report their maximum crack heights from the ID surface.The API 510 Pressure Vessel and API 570 Piping inspection codes have been modified to identify certain applications requiring the use of ultrasonic testing shear wave examiners that have passed a performance demonstration.These sizing techniques are applicable to manual examinations only. The Ultrasonic Phased Array Crack Sizing Procedure document (API-UT-11 below) outlines the requirements for contact phased array crack sizing methods using refracted longitudinal wave and shear wave techniques for carbon steel materials.This procedure is applicable to carbon steel material thickness from 0.375 inches to 1.0 inches. The designed procedure provides guidelines and techniques for ultrasonic sizing of planar cracks which originate at the opposite side of the scanning surface or the inside diameter. The API QUSE-PA Ultrasonic Testing Examiners (Sizing) certification exam addresses equipment and sizing evaluation techniques for crack height sizing.
