Analytical results reflect the make tip of the materials only In the areas sampled. This 'Summary of Ar,aMlcal Results' shjll not be reproduced except In full, wlgrout the written approval of JLC Laboratory, and It must not be used by client to clalm product endorsement by NVLAP or any agency of the U.S. Government. This method is riot applicable to samples containing large amounts of fine fibers below the resolution of the light mkroscops. The value of this method is limier to the quantitative Identification of asbestos and the eernl-quandtallve determination of asbestos content of bulk apn{ples, expressed ass percentage of the protected area. Quantftatlon of asbestos content was determined with a visual volume estimate, a calibrated Visual area eadNte, apolor point counting procedure. CAUTION: Other fibers with optical propeq ea similar to asbestos may give positive IMarterencea and will be considered asbestos under this methodology. Also, PLM is not consistently reliable In detecting gsbestas In floor coverings and similar non-friable orraanlceiiy-band materials. Quantitative transmission electron microscopy Is currently the only method that am be used to determine If this material can be considered or treated as nort-aebeetoa containing.
