description	PURPOSE:To rapidly and purely discriminate the presence or absence of asbestos in a fiber reinforcing material by physically crushing the fiber reinforcing material and then loading the crushed powder on a slide glass, dripping the crushed powder and a dipped liquid with a specific refractive index and then placing a cover glass as a sample, and then observing light through the sample from a light source via a dispersion dyeing lens. CONSTITUTION:The presence or absence of asbestos is judged by the dispersion dyeing method using a crushed powder obtained by crushing the sample of a fiber reinforcing material. First, for judging the presence or absence of the asbestos by mounting the crushed powder on a slide glass, a dipping liquid with the refractive index being within the range of 1.550+ or -0.010 is dropped and further a sample obtained by placing the cover glass is observed by a microscope with a light source, a rotary stage, and a dispersion dyeing lens by the dispersion dying method. Light through the sample from the light source is observed via a lens. Then, when a peripheral part alternately repeats red- orange color and blue color for two times as the rotary stage is rotated by one turn, asbestos are detected and discriminated.
