Analytical, results reflect the make up of the materials only in the areas sampled. This "Summary of Analyh’cal Results" shall not be reproduced except in full, without the writte approval of JLC Laboratory, and it must not be used by client Io 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 idenfification of asbestos and the semi-quantHative determination of asbestos content of bulk samples, expressed as a percentage of the protected drea Quantitation of asbestos content was ’ determined with a visual.volume eslimate. a calibrated visual area estimate, and/or point counting procedure. CAUTION: Other fibers with optical properties similar Io asbesfo 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.
