Kriipekõvadusmõõturiga test koosneb kriimustuse tegemiseks vajaliku koormuse mõõtmisest, milleks tõmmatakse etteantud koormusega varustatud teemantotsak edasi-tagasi katsetatava materjali siledale pinnale ja kõvadusarv on mass grammides, mis on vajalik standardse kriimustuse saamiseks.
The sclerometer test consists of measuring the amount of load required to make a scratch. In test a weighted diamond point is drawn, once forward and once backward, over the smooth surface of the material to be tested, and the hardness number is the weight in grams required to produce a standard scratch.
