Analysis by
Polarized Light Microscopy-Dispersion Staining (PLM-DS)
Method of Sample Preparation and Analysis:
All samples were prepared and analyzed in accordance with the EPA "Method for the Determination of Asbestos in
Bulk Building Materials" USEPA/ 600/R-93/I 16, July, 1993
Instrumentatioiu
Olympus PLM, Model BH-2/VM stereomicroscope Model VMZ Ix-4x.
Analytical results reflect the make up of the materials only in the areas sampled. This "Summary of Analytical Results" shall not be reproduced except
in full, without the written approval of JLC Laboratory, and it must not be used by client to claim product went by NVL.AP or any agency of the
U.S. Government. This method is not applicable to samples containing large amounts of fine fibers below the resolution of the light microscope. The
value of this method is limited to the quantitative identification of asbestos and the semi-quantitative determination of asbestos content of bulk samples,
expressed as a percentage of the projected area. QuanMation of asbestos content was determined with a visual volume estimate, a calibrated visual
area estimate, and/or point counting procedure. CAUTION: Other fibers with optical properties similar to asbestos may give positive interferences
and will be considered asbestos under this methodology. Also, PLM is not consistently reliable in detecting asbestos in floor coverings and similar
non-friable organically bound materials. Quantitative transmission electron microscopy is currently the only method that can be used to determine
if this material can be considered or treated as non-asbestos containing.
