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.
The Leeb Rebound Hardness Test (LRHT) invented by Swiss company Proceq SA is one of the four most used methods for testing metal hardness. This portable method is mainly used for testing sufficiently large workpieces (mainly above 1 kg). [citation needed] It measures the coefficient of restitution. It is a form of nondestructive testing.
The technique is very sensitive and can detect tight cracks. Surface inspection can be performed both on ferromagnetic and non-ferromagnetic materials. [8] [9] Tubing inspection is generally limited to non-ferromagnetic tubing and is known as conventional eddy current testing.
Mechanical testing: hardness testing, tensile testing, Charpy impact testing Chemical testing: microprobe analysis, energy dispersive spectroscopy Non-destructive testing : Non-destructive testing is a test method that allows certain physical properties of metal to be examined without taking the samples completely out of service.

In the field of industrial ultrasonic testing, ultrasonic thickness measurement (UTM) is a method of performing non-destructive measurement (gauging) of the local thickness of a solid element (typically made of metal, if using ultrasound testing for industrial purposes) based on the time taken by the ultrasound wave to return to the surface.
BHN = load in kilograms divided by the spherical area of the indentation in square millimetres (refer to Brinell scale for method of calculation) It is a rapid, non-destructive (except at the surface being tested) means of determining the hardness of metals. This area is a function of the ball diameter and the depth of the indentation.
