Read the first 7 Codes and Standards flashcards as text

  1. Which ASTM standard covers the standard practice for liquid penetrant examination?

    Answer: ASTM E165

    ASTM E165 is the Standard Practice for Liquid Penetrant Examination for General Industry.

  2. In the context of NDT codes, what is a 'procedure qualification record' (PQR)?

    Answer: A record documenting the variables used during a welding procedure specification test

    A PQR records the actual welding variables used during a test weld and the results of testing used to qualify a Welding Procedure Specification (WPS).

  3. According to ASME Section V Article 4, what is the maximum film density allowed for radiographic examination of welds in steel?

    Answer: 2.0 to 4.0 H&D

    ASME Section V Article 4 requires radiographic film density to be between 2.0 and 4.0 (H&D) in the area of interest for steel radiography.

  4. Which code governs the inspection of aboveground atmospheric storage tanks?

    Answer: API 653

    API 653 is the Tank Inspection, Repair, Alteration, and Reconstruction standard for aboveground atmospheric storage tanks.

  5. In ANSI/ASNT CP-189, what distinguishes it from SNT-TC-1A regarding personnel certification?

    Answer: CP-189 establishes standardized national requirements while SNT-TC-1A is an employer-based recommended practice

    ANSI/ASNT CP-189 is a national standard with minimum requirements for certification, while SNT-TC-1A is a recommended practice that employers adapt for their own written practice.

  6. What is the purpose of an image quality indicator (IQI) in radiographic testing?

    Answer: To demonstrate the sensitivity and quality of the radiographic image

    An IQI (also called a penetrameter) verifies that the radiographic technique achieves the minimum required image quality and sensitivity.

  7. Under MIL-STD-1689 (Navy surface ship welding), which NDT method is required as the primary method for full-penetration hull welds?

    Answer: Radiographic testing

    MIL-STD-1689 requires radiographic testing as the primary volumetric examination method for full-penetration hull structure welds.
