Sample Analysis by:
Polarized Light Microscopy-Dispersion Staining (PLM-DS) CHRY = Chrysotile Asbestos PAPF = Paper Fiber
AMOS = Amosite Asbestos MINW = Mineral Wool
CROC - Crocidolite Asbestos FBGL = Fiberglass
Method of SamA ple Preparation and Analysis: ACTN = Actinolite Asbestos SYNF = Synthetic Fibers
All samples were prepared and analyzed In accordance with the EPA TREM = Tremolite Asbestos CELL = Cellulose
"Method for the Determination of Asbestos In Bulk Building Materials" ANTH = Anthophylite Asbestos NFIB = Non-Fibrous
USEPA/ 600/ R-931116, July 1993. ORGM = Organic Material
WOLL = Wollastonite

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 writte
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. 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 protected area. Quantitatlon 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 asbesto
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 b
considered or treated as non-asbestos containing.
