In the last few decades, many researchers have been studying how hardness measurements can be affected by possible influence variables (i.e. velocity of the indenter, dwell times, temperature, etc). This interest is particularly motivated by the newl

The value of the acceleration due to gravity is of interest in a wide range of fields, from geophysics, geodesy, water-floor monitoring, and hazard forecasting to oil, gas and mineral exploration. For this purpose, relative or absolute gravimeters ha

For the measurement of the acceleration due to gravity, INRiM developed a transportable ballistic rise-and-fall absolute gravimeter, the IMGC-02. It uses laser interferometry to measure the symmetrical free rising and falling motion of a test mass in

A correction method for Vickers indenters squareness measurement due to the tilt of the pyramid axis
In ISO 6507-3 it is required that the quadrilateral base of Vickers indenter has angles of 90° ± 0.2°. Squareness angles are usually evaluated through optical techniques by measuring the angles between two consecutive faces, which correspond to th
