Re: [MW:7006] Qualitative and Quantitative Testing

Qualitative tests are the ones which do not give any measure or value of the quantity, like microstructures, liquid penetrant test,etc. In other case, a value is given as outcome of the test like tensile test, impact test, radiography, UT,etc. So in your case both CTOD & CVN are quantitative tests, as both give a value of the measurand. Like CTOD gives the JIC,KIC and CVN energy in Joules/ft.lb
         In CTOD a predefined crack is made and its rate of growth is measured to get the fracture toughness, whereas in CVN a predefined notch is made to get the energy absorbed, also here the energy is given in a sudden single blow. I think this would clear your query.
