This method is intended to provide the methods of preparation and analysis for the presence and quantitation of asbestos in vermiculite products including the products that contain other materials. The asbestos will be identified and counted by standard microscopical procedures consistent with the suite of ASTM asbestos methods for air (D6281), Dust (D5755) and Soil (D7521).

Thousands of homes were constructed with vermiculite attic insulation and vermiculite is a constituent in many building products. Vermiculite mined in Libby, Montana has been found to contain asbestos and asbestos-related disease has been found in the general population of Libby. The users of this method will be regulators, home owners, environmental consultants.

The title and scope are in draft form and are under development within this ASTM Committee.
