This paper addresses the issue of the improvement of the experimental procedure of the 10 ° off-axis tensile test by using oblique tabs. It is shown that oblique tabs significantly increase the maximum shear stress at failure and that unlike straight-tabbed specimens failing in the tabbed area, oblique-tabbed specimens failed neatly in the gauge section. It also appears that composite tabs are more appropriate than aluminium tabs. Finally, it is shown that although a state of homogeneous shear stress is now achieved in oblique-tabbed specimens, the presence of transverse tensile stress prevents the direct measurement of the shear strength and that only a lower bound is obtained
