API Bull 587-2021 pdf free download.Guidance for the Development of Ultrasonic Examiner Qualifcation Programs.
1 Purpose The purpose of this publication is to provide owner/users with guidelines for developing basic in-house qualifcation programs to identify industry-qualifed ultrasonic testing (UT) angle beam examiners that are equivalent to those possessing an ultrasonic angle beam qualifcation from API (e.g. API QUTE/QUSE detection and sizing tests) for inspection of pressure equipment and piping as required by API 510 and API 570. The availability of high- quality and accurate UT data is often the cornerstone for weld and base metal discontinuity detection and sizing for equipment integrity assessments. As a result, API has implemented several certifcation programs to assist in defning the minimum criteria for assessing the performance of UT technicians. Examinations for these programs are administered diferently than other Individual Certifcation Program (ICP) certifcations in that they are based on hands-on performance demonstration tests. It should be noted that UT certifcations are issued by accredited NDE certifcation authorities, such as the American Society for Nondestructive Testing (ASNT), and these API UT ICP certifcations are considered performance demonstration qualifcations by such NDE certifcation schemes. 1.1 Scope This publication outlines the general guidelines for the development of owner/user ultrasonic examiner qualifcation programs that are consistent with API performance demonstration programs for detection, characterization, and crack height sizing of weld discontinuities in weldments. The performance demonstration programs covered in this publication include the following: 1.1.1 Qualifcation of Ultrasonic Testing Examiners for Detection and Characterization of Flaws Using Manual Angle Beam Testing: QUTE QUTE exam description: Exam candidates use manual ultrasonic faw-detection instruments to examine new construction carbon steel pipe and plate welds manufactured to ASME code requirements. Candidate performance measures include faw detection, characterization, length sizing,

3 Terms, Defnitions, Acronyms, and Abbreviations 3.1 Terms and Defnitions For the purposes of this document, the following defnitions apply. 3.1.1 centerline crack A crack that occurs longitudinally in the center of a weld bead during solidifcation. 3.1.2 crack A fracture of the material structure that separates the material without complete separation. 3.1.3 incomplete root fusion A weld defect where the root of the weld is unfused. 3.1.4 incomplete root penetration A weld defect where the depth of weld metal fused is incomplete. 3.1.5 grading unit A length of a weld that may contain a weld discontinuity on either side of the weld in the QUTE and QUPA performance demonstration specimens. (e.g. 2 in.–3 in.). A designated grading unit for a given exam may or may not be from the same exam specimen. 3.1.6 lack of sidewall fusion (LOF) A non-standard term indicating a weld discontinuity in which fusion did not occur between weld metal and fusion faces or adjoining weld beads. 3.1.7 owner/user An owner or user of pressure vessels or piping who exercises control over the operation, engineering, inspection, repair, alteration, maintenance, pressure testing, and rerating of those pressure vessels and piping systems.1.1.3 Qualifcation of Ultrasonic Testing Examiners for Manual UT-Angle Beam Crack Sizing: QUSE QUSE exam description: Exam candidates use manual ultrasonic faw detector instrumentation to size opposite side cracking in new construction carbon steel plate welds with and without weld crowns in place. 1.1.4 Qualifcation of Ultrasonic Testing Examiners for Manual UT-Phased Array Crack Sizing: QUSE-PA QUSE-PA exam description: Exam candidates use manual ultrasonic phased array instrumentation to size opposite side cracking in new construction carbon steel plate welds with and without weld crowns in place. 1.2 Weld specimens for the QUTE, QUPA, QUSE, and QUSE-PA exams are single- or double-bevel carbon steel plate or pipe welds 0.50 in.–1.00 in. (12.5 mm–25 mm) in thickness. See Section 4 for specimen details. 2 Normative References The following referenced documents are indispensable for the application of this document.
