Method EPA 600/R-93/116

Method for the Determination of Asbestos in Bulk Building Materials

This method is for the determination of asbestos in a variety of bulk building materials including loose-fill insulations, acoustic and thermal sprays, pipe and boiler wraps, plasters, paints, flooring products, roofing materials and cementitious products.  A sample of the bulk material is analyzed using polarized light microscopy (PLM). 

Typical sample sizes submitted for analysis are a one inch by one inch square.  If the bulk material has layers then each layer of the material should be analyzed.

The method is not applicable for samples containing large amounts of fibers that are below the resolution of the PLM (< 0.3 microns). 

Sample results are reported as the identification and semi-quantitation of asbestos along with the identification where possible of fibrous non-asbestos materials, mineral components and matrix materials.  Results are typically expressed as a percentage of the total sample.
