Proceq
Proceq SA of Switzerland is a technology company in the nondestructive testing space. The company name Proceq is taken from a combination of the words “processes” and “equipment”. The main focus is on imaging solutions for non destructive testing of concrete structures, metal hardness testing, paper roll hardness testing and rock testing. Proceq is well known for patenting the Original Schmidt concrete test hammer as well as the Leeb rebound principle and is also the owner of the “Pundit” trademark for ultrasonic test equipment. The company is still privately owned by the founder's family Brandestini/Valsangiacomo. History Proceq SA was founded on 8 April 1954 by Antonio Brandestini, when it opened its first office in Zurich, Switzerland. During its early years, the company concentrated on developing and selling special equipment for pre-stressed concrete engineering, a field which was, at that time, in its infancy. It also developed bearings for the constructi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leeb Rebound Hardness Test
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). It measures the coefficient of restitution. It is a form of nondestructive testing. History The Equotip (later on also called simultaneously as Leeb method) rebound hardness test method was developed in the year 1975 by Leeb and Brandestini at Proceq SA to provide a portable hardness test for metals. It was developed as an alternative to the unwieldy and sometimes intricate traditional hardness measuring equipment. The first Leeb rebound product on the market was named “Equotip”, a phrase that still is used synonymously with “Leeb rebound” due to the wide circulation of the “Equotip” product. Traditional hardness measurements, ''e.g.'', those of Rockwell, Vickers, and Brinell, are stationary, requiring fixed workstations in seg ...

Schmidt Hammer
A Schmidt hammer, also known as a Swiss hammer or a rebound hammer or concrete hammer test, is a device to measure the solid mechanics, elastic properties or strength of concrete or rock (geology), rock, mainly surface hardness and penetration resistance. It was invented by Ernst Heinrich Wilhelm Schmidt, a Swiss engineer. The hammer measures the rebound of a spring-loaded mass impacting against the surface of a sample. The test hammer hits the concrete at a defined energy. Its rebound is dependent on the hardness of the concrete and is measured by the test equipment. By reference to a conversion chart, the rebound value can be used to determine the concrete's compressive strength. When conducting the test, the hammer should be held at right angles to the surface, which in turn should be flat and smooth. The hammer comes with a small grinding stone to create a flat and smooth surface, before the test. The rebound reading will be affected by the orientation of the hammer: when used ...
