    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.

[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. 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.

  5. Infrared and thermal testing - Wikipedia

    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 ...

  8. 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 ...

  9. Phased array ultrasonics - Wikipedia

    en.wikipedia.org/wiki/Phased_array_ultrasonics

    Phased array is widely used for nondestructive testing (NDT) in several industrial sectors, such as construction, pipelines, and power generation.This method is an advanced NDT method that is used to detect discontinuities i.e. cracks or flaws and thereby determine component quality.
