Dear Ms. Pope:
Enclosed is written confirmation of the analytical result for the (5) bulk samples delivered to our lab on Wednesday, October 2, 1991. Sample number 91156 consisted of two separate compo nents which had to be analyzed individually.
The sample analyses were performed at our lab with a Nikon LabophotPol microscope. Standard oil immersion and optical staining techniques were used for asbestos identification. The Interim Method for the Determination of Asbestos in Bulk Samples (40 CFR Part 763, Appendix A, Subpart F) was used. Envirotest, Inc. is a National Institute of Standards and Technology NVLAP-accredited laboratory (#1595) for asbestos analysis.
The following analytical results pertain only to the samples analyzed. Envirotest, Inc. assumes no responsibility for whether the samples accurately represent the material in question nor for any subsequent use or interpretation of these analytical results.
If you have any questions regarding the sample analyses, please call. We appreciate the opportunity to be of service to you.
Sincerely,
Chief Executive Officer Envirotest, Inc.
