TAPPI T 1016 OM 2010 is an official test method for measuring the average fiber diameter, or distribution of diameters, in nonwoven fiberglass mats. It covers sample preparation by furnace treatment, microscope slide mounting, measurement at 1000X magnification, data calculation, reporting, and precision considerations.
The method specifies required apparatus, including a high-magnification microscope, muffle furnace, microscope slides, cover glass, and certified refractive index liquid. It also provides procedures for measuring at least 100 individual fibers and reporting results for separately identifiable fiber types or wide diameter distributions.
Application Scope: Quality control, laboratory analysis, and materials characterization of nonwoven fiberglass mats and their constituent fibers.
