Method 9002

Asbestos (Bulk) by PLM

This method is useful for the qualitative identification of asbestos and the semi-quantitative determination of asbestos content of bulk samples. The method measures percent asbestos as perceived by the analyst in comparison to standard area projections, photos, and drawings, or trained experience. The method is not applicable to samples containing large amounts of fine fibers below the resolution of the light microscope NOTE: NVLAP requires the use of EPA Method 600 for bulk asbestos determination by PLM.
