<p>A test strip is grooved on the reverse face near one end and the tab so formed separated and passed either through a sharp edged slot in a support plate or between two rollers forming part of the support through two counter rotating tension rollers. The force required to pull off the metal foil from the substrate is measured either directly by load cells etc. in the framework of the support plate or as a derived quantity from measured torque applied to the tension rollers.</p> |
