Codes and Standards Flashcards

An NDT inspector is required to perform ultrasonic testing on a new power boiler during fabrication. Which section of the ASME Boiler and Pressure Vessel Code provides the detailed methods and procedures for conducting this examination?

Answer: ASME Section V - Nondestructive Examination

ASME Section V is the primary reference for how to perform NDT examinations. While other sections like Section I or Section VIII mandate the use of NDT and provide acceptance criteria, Section V details the specific procedures, equipment requirements, and methodologies for various NDT methods.

A welding inspector is overseeing the fabrication of a new steel pedestrian bridge. Which of the following codes would be the primary governing document for the welding and inspection requirements?

Answer: AWS D1.1 - Structural Welding Code — Steel

AWS D1.1, the Structural Welding Code for Steel, is the preeminent standard for the welding, fabrication, and erection of welded steel structures, such as buildings and bridges. The other options are for different applications: API 1104 is for pipelines, ASME IX is for qualifying welders and procedures (often referenced by other codes), and ASTM E164 is a specific method practice, not a construction code.

What is the primary purpose of ASNT's Recommended Practice No. SNT-TC-1A?

Answer: To provide guidelines for employers to establish their own written practice for the qualification and certification of NDT personnel.

SNT-TC-1A is a recommended practice that provides a framework for employers to create their own in-house, employer-based NDT certification programs. It is not a mandatory standard itself but a guideline that requires the employer to create a formal 'Written Practice' detailing their specific requirements for training, experience, and examination.

An NDT Level II technician performs a liquid penetrant examination on a weld for a new pressure vessel built to ASME Section VIII, Div. 1. The technician finds several rounded indications. In which document would the technician find the specific criteria to determine if these indications are acceptable or rejectable?

Answer: ASME Section VIII, Div. 1, Mandatory Appendix 8

While ASME Section V provides the methodology for performing the liquid penetrant test, the acceptance and rejection criteria are found in the referencing construction code, which in this case is ASME Section VIII, Division 1. Specifically, Mandatory Appendix 8 of Section VIII, Div. 1 contains the acceptance standards for liquid penetrant examination.

An oil refinery needs to conduct an in-service inspection of its existing process piping systems to assess for corrosion and other degradation. Which American Petroleum Institute (API) code specifically governs the inspection, rating, repair, and alteration of these in-service piping systems?

Answer: API 570 - Piping Inspection Code

API 570 is the specific code dedicated to the in-service inspection, rating, repair, and alteration of metallic and FRP piping systems. API 510 is for pressure vessels, API 653 is for storage tanks, and API 1104 is for the construction of new pipelines.

Which of the following best describes the role of ASTM International standards, such as ASTM E709 (Magnetic Particle Testing) or ASTM E1417 (Liquid Penetrant Testing), within the larger framework of NDT codes?

Answer: They provide detailed, consensus-based procedures and practices for how to perform a specific NDT method.

ASTM International standards provide standardized, detailed methodologies and practices for performing specific NDT tests. Broader construction codes, like those from ASME or AWS, will often reference these ASTM standards as the required procedure to follow when an examination is mandated.
