This standard specifies the method for measuring the cross-sectional shape parameters of special-shaped fibers and the characterization and calculation methods for the degree of fiber deformation and the coefficient of variation of the degree of deformation. This standard applies to all kinds of special-shaped fibers that can be clearly imaged.
