    The instrument uses the world's first patented non-destructive testing method for concrete. 1950 – J. Kaiser introduces acoustic emission as an NDT method. (Basic source for above: Hellier, 2001) Note the number of advancements made during the WWII era, a time when industrial quality control was growing in importance.

    A procedure for ultrasonic testing is outlined in ASTM C597 - 09. [9]In India, till 2018 ultrasonic testing was conducted according to IS 13311-1992.From 2018, procedure and specification for Ultrasonic pulse velocity test is outlined in IS 516 Part 5:Non destructive testing of concrete Section 1:Ultrasonic Pulse Velocity Testing.

  4. Robotic non-destructive testing - Wikipedia

    en.wikipedia.org/.../Robotic_Non-Destructive_Testing

    Robotic non-destructive testing (NDT) is a method of inspection used to assess the structural integrity of petroleum, natural gas, and water installations. Crawler-based robotic tools are commonly used for in-line inspection (ILI) applications in pipelines that cannot be inspected using traditional intelligent pigging tools (or unpiggable pipelines).

  5. Thermal integrity profiling - Wikipedia

    en.wikipedia.org/wiki/Thermal_integrity_profiling

    Thermal Integrity Profiling (TIP) is a non-destructive testing method used to evaluate the integrity of concrete foundations. It is standardized by ASTM D7949 - Standard Test Methods for Thermal Integrity Profiling of Concrete Deep Foundations. The testing method was first developed in the mid 1990s at the University of South Florida.

    en.wikipedia.org/wiki/Infrared_and_thermal_testing

    "Infrared thermography, a nondestructive, remote sensing technique, has proved to be an effective, convenient, and economical method of testing concrete. It can detect internal voids, delaminations, and cracks in concrete structures such as bridge decks, highway pavements, garage floors, parking lot pavements, and building walls. As a testing ...

    en.wikipedia.org/wiki/Infrared_non-destructive...

    This principle can be used also for non-contact [1] infrared non-destructive testing (IRNDT) of materials. [2] The IRNDT method is based on an excitation of a tested material by an external source, which brings some energy to the material. Halogen lamps, flash-lamps, ultrasonic horn or other sources can be used as the excitation source for the ...

  9. Ground-penetrating radar - Wikipedia

    en.wikipedia.org/wiki/Ground-penetrating_radar

    It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables or masonry. [1] This nondestructive method uses electromagnetic radiation in the microwave band ( UHF / VHF frequencies) of the radio spectrum , and detects the reflected signals from subsurface structures.
