To perform the quantitative Vickers hardness test, samples of components are struck that has a pyramid of standardized Proportions using a identified pressure – a diamond crystal is useful for the pyramid to permit an array of resources to generally be tested.
Closely associated with Hearts and Arrows viewers will be the ASET which exams for light leakage, mild return, and proportions. The ASET (and Pc simulations from the ASET) are used to check for AGS Reduce grade.[40] Proponents of those devices argue they help sellers display The sunshine effectiveness with the diamond Besides the standard four Cs.
