*insufficient material submitted **TEM recommended ***Not analyzed positive stop Sample Anal sis by: Polarized Light Microscopy-Dispersion Staining (PLM-DS) Method of Sample Preparation and Analrs1s: All samples were prepared and analyzed in accordance with the EPA "Method for the Determination of Asbestos in Bulk Building Materials" USEPA/ 600/R-93/116, July, 1993 Uum ow Olympus PLM, Model BH-2/VM steeornicroscope Model VMZ lx-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 endorsement by NVLAP or any agency of the U.S. Govemntent. This method is not applicable to samples coning large amounts of fine fibers below the resolution of the light microscope. The value of this method is limited to the gi h.bve identification of asbestos and the semi-quantitative determination of asbestos content of bulk samples, expressed as a percentage of the projected area. won 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.
