Test results give some indication of the apparent fiber length distribution in the sample tested. Sieves are ideally suited to measure particle size and particle size distribution when all three axes of the particle are equidimensional or the particle is of spherical shape. Asbestos fibers differ considerably from these ideal conditions and, therefore, results depart ...
