A method of performing a shear test using a test tool comprises providing a surface with an aperture (92) formed in the surface, indexing a wire (93) through the aperture (92) to protrude past the surface, contacting the portion of a wire (93) protruding past the surface with the test tool (94) to shear the portion of the wire (93) off the remainder of the wire, measuring the shear load applied to the test tool (94) by the portion of the wire while the portion of the wire is being sheared off by the test tool (94), and comparing the measured shear force with a shear force measured by a different test tool which was brought into contact with another portion of the wire (93). |
