Please find attached the analytical results for the bulk asbestos samples received 12/08/95 under Project No. ASB 1195.
The bulk asbestos has been analyzed by visual estimation based on EPA--600/M4--82--020 (Dec. 1982) optical microscopy test method.
I can be reached at Ext. 240 if you have any questions or comments.

Dear Mr. Jacobi:
Samples A21115 through A21121 have been analyzed by visual estimation based on EPA-600/M4-82-020 December 1982 optical microscopy test method including phase contrast, polarized light, dispersion staining, and stereo microscopy. Accuracy increases with increasing asbestos concentration.
If these samples are related to a demolition or are subject to NE5HAPS 40CFR part 61 regulations, these regulations mandate that any sample containing less than 1% asbestos must be analyzed by point count. If asbestos is reported to be between 1% and 10%, see EPA "Clarification of asbestos NESHAP requirements to perform point counting" (copy available).
This report relates only to the items tested. This report must not be used to claim product endorsement by the NYLAF, the National Institute of Standards and Technology, or any agency of the U.S-. Government. The results of analysis are as follows:
Tb A??.!?. Field 1952744-1 Bulk As-bsstoo This is 2% chrysotile asbestos and 15% amosite asbestos in gray and white plaster.
Lab A21116. Field L952744-2 Bulk Asbestos This sample contains three types of material: The first type is green paint; the second type is 20% chrysotile asbestos in black binder; the third type is 10% chrysotile asbestos and 60% rockwool in light gray binder. This sample is non-homogeneous. The overall asbestos concentration is 11%.
The first type is 1% of the sample. The second type is 9% of the sample. The third type is 90% of the sample.

Asbestos is none
Lab A21118. Field L952744-4 Bulk Asbestos This sample contains five types of material: The first type is gray paint; the second type is cross woven fiberglass bundles; the third type is 5% plant fiber in off-white plaster with a trace of green paint; the fourth type is 5% plant fiber and 2% synthetic fiber in white plaster with a trace of green paint; the fifth type is black tar binder with 5% vollastonite. This sample is nonhomogeneous. Asbestos is none detected.
The first type is 2% of the sample. The second type is 8% of the sample. The third type is 40% of the sample. The fourth type is 45% of the sample. The fifth type is 5% of the sample.
Lab A21119. Field L952744-5 Bulk Asbestos This is 50% chrysotile asbestos in hard, white binder with rust.
Lab A21120. Field L952744-6 Bulk Asbestos This is woven fiberglass with a light coating of gray particulate. Asbestos is none detected.
Lab A21121. Field L952744-7 Bulk Asbestos This is 20% chrysotile asbestos in gray cement. non-homogeneous.
