Analytical results reflect the make up of the materiels 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 endorserftenf by NVLAP or any agency of the U.S. Government. This method is not applicable to
samples containing large amounts of flee fibers below the resolution of the IM microscope. The value of this method is limited to the quantitative Identification of asbestos
and the ee'nlquanhItaTlve deters lnatlort of asbestos content of bilk samples, expressed ae a percentage of the protected area. Ouartdtallon of asbestos content was
determined with a visual volume estimate, a calibrated visual area estttrtate, andlor point counting procedure. CAUTION: Other fibers wilts optical properties similar to asbestos
may give positive Ifiterferogces and will be considered asbestos under tots rftethodology. Also, PLM Is not consistently relieple In detecting asbestos In floor coverings and
similar non.f labia organically-bound materials. Quantitative transmission electron microscopy Is currently the only method that can be used to detemtlne If this material can be
considered or treated as r on-asbestos containing.
