One reason for the lack of discrimination in many tear tests is a direct influence of compound modulus on measured tear strength.Fig.X1.1 is a plot of D 624 Die C tear strength as a function of modulus (300 %) for data taken from the literature.This shows tear strength to be strongly correlated with modulus (correlation coefficient of 0.90).Thus both modulus and tear strength are being measured in unknown proportions.Theoretical calculations show that the tear rupture force of Die C specimen measurements is approximately equal to the square root of the tangent modulus-tear strength product.
