<p><span style="font-family: times new roman,times; font-size: medium;">This tester applies a cut to the sample with a straight blade. A number of cuts are made each using a new blade and using a different contact force.</span></p>

<p><span style="font-family: times new roman,times; font-size: medium;"> </span></p>

<p><span style="font-family: times new roman,times; font-size: medium;">A graph is then plotted of cutting stroke length compared to blade loading to predict the force at which the blade will just penetrate the material at 20 mm stroke. That force in newton gives the cut index and EN 388:2003 includes a potential correlation with the blade cut index value such as that produced by STM 611.</span></p>
