Analytical results reflect the make tip of the materials only in the areas sampled, Thla "Summary of Analytial 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 agertey of tip U.S. Government This method is not applicable to samples containing large amounts of fine fibers below the resolution of the Iight microscope. The value of this method Is limited to the quandtagve Identification of asbestos and the semlquanthattve determination of asbestos content of bxrtk samples, expressed as a percentage of pie protected area. Auandtatlon of asbestos content was determined with a visual volynme eadgfate, a calibrated vlsyal area estimate, and/or point counting proadpre. CAUTION: Other fibers with optical properties similar to asbestos may give positive Interferwices and will be considered asbestos under this methodology. Also, PLM Is r at consletently reliable In detecting asbestos In floor caavarfngs and elmrtilar nor-Mable organicafy-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-esbeatoa containing.
