ASTM D-5755-03

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).

The method is applicable for an estimate of surface loading of asbestos structures starting from approximately 1000 structures per square centimeter.
