Among industrial injuries, those related to hands are most frequent. The mechanical aggressions essentially depend on the type of activity and most of them are easy to simulate. However, the objective and simple measurement of the cutting resistance of any protective material comes up against the reproducibility of the process, considering the delicate specifications and measurements of the sharpness of the blades used for this purpose. Moreover, we also have to distinguish between cutting by slicing (motion parallel to the surface) and cutting by impact (motion perpendicular to the surface). Whatever the case, the sharpness of the blade needs some sophisticated means of observation, which is expensive. In 1987, I T F - LYON (Institut Textile de France), at the request of I N R S (Institut National de Recherche et de Sécurité), developed a method to measure the cutting effects by slicing where blade sharpness supervision is not necessary with certain limits.
This method consists of measuring the cutting effects on a given material against those measured on a defined control specimen.
