Scope:

This is a method by which the coarseness (weight per unit length) of the fibers in a pulp may be ascertained by counting the crossings of a known weight of fibers per unit area on a prepared slide over lines of known length. The crossings are counted with a microscope and mechanical stage, by traversing the slide over a series of 5-cm distances.

If it is also required to determine the length of the fibers in a sample in accordance with TAPPI T 232 "Fiber Length of Pulp by Projection," instead of using a microscope, the fiber crossings over lines of known equivalent length may be counted when the images of the fibers are projected on a screen as described in T 232.
