ASTM D-5756-02

As with the ASTM D 5755 method, this method employs a micro-vacuuming sampling technique to collect dust off of various surfaces.  The samples are then analyzed by TEM to identify asbestos structures based on morphology, Selected Area electron diffraction (SAED), and X-Ray analysis (EDXA).

This method provides results in mass of asbestos per unit area of sample surface OR mass of asbestos per mass of sampled dust.
