Crosshole sonic logging (CSL) is a method to determine the structural integrity of drilled shafts and other concrete piles. The CSL method is considered to be more accurate than sonic echo testing in the determination of structural soundness of concrete within the drilled shaft inside of the rebar cage. This method provides little indication of ...
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.
The free tool was officially closed by the owners, IBM, on February 1, 2008. [2] The software is now available as part of IBM's Rational Policy Tester Accessibility Edition. [1] [3] Currently, the Web Accessibility Evaluation Tool (WAVE) provides this free service at wave.webaim.org.
The TDR test requires minimal of preparation and is able to find defects corresponding to cracks, reductions in section and zones of poor quality concrete The test is based on wave propagation theory. The name "low-strain dynamic test" stems from the fact that when a light impact is applied to a pile it produces a low strain.
WebAIM (Web Accessibility in Mind) is a non-profit organization based at Utah State University in Logan, Utah.WebAIM has provided web accessibility solutions since 1999. . WebAIM's mission is to expand the potential of the web for people with disabilities by providing the knowledge, technical skills, tools, organizational leadership strategies, and vision that empower organizations to make ...
Acoustic resonance technology (ART) is an acoustic inspection technology developed by Det Norske Veritas over the past 20 years. ART exploits the phenomenon of half-wave resonance, whereby a suitably excited resonant target (such as a pipeline wall) exhibits longitudinal resonances at certain frequencies characteristic of the target's thickness.
The company was started in 1999 and produces accessibility testing software in addition to offering accessibility consulting services and training. [citation needed] In June, 2015 Deque open-sourced the accessibility rules engine axe-core. [2] In May 2020, the WorldSpace brand name was retired and replaced by axe for each of Deque's products.

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.
