Analyttoal results reflect the make up of the materials only in the areas sampied. This "Summary of Analytical Results° shall not be reproduced except In full, without the written
approval of JLC Laporatory, and It must not be used by client to claim product andoreemern by NVLAP or any agency of the U.S. Goveminent This Method Is not applicable to
samples containing large almounte of fine fibers below the resolution of the fight microscope. The value of this mettpod Is llr>flled to tita quantitative identification of asbestos
and the sefnl-quantitative determination of asbestos content of bulk samples, expressed as a percentage of the protected area. Ouantltallon of asbestos content was
determined wItit a visas( volume estimate, a calibrated visual grey estimate, and/or point counting procedure. CAUTION: Other fibers with optical properties similar to asbestos
may give positive inlerlerencas and will be considered asbestos under this methodology. Also, PLM Is not consistently reMbie in detecting asbestos in floor coverings and
similar non4rfeble orgenIcafly-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 norraebestos containing.
