Client Project #:
Techtron Project #: 13178 Analyzed by: Joshua Kranz
Date Samples Submitted: 7/29/2020 Date Samples Analyzed: 7/30/2020
Number of Samples Analyzed: 7
Test Report: Asbestos Bulk Materials Identification by PLM
Following are the results of material samples obtained for asbestos identification analysis. Samples were
observed at 42X magnification and suspect fibers were isolated from the bulk samples for observation
under polarized light microscopy. The fibers were then evaluated under polarized light microscopy for
extinction angle, sign of elongation, and morphology. Dispersion staining was performed using Cargille
dispersion oils to observe color changes of fibers at various orientations.
Analysis was performed according to EPA method 600/R-93/116. This method has a reporting limit to
<1% asbestos, in volumetric concentrations. Bulk samples were checked for the following types of
asbestiform minerals: chrysotile, amosite, crocidolite, anthophyllite, and tremolite-actinolite.
All sample details and results are listed in the table below.

NAFD = No Asbestos Fibers Detected
NAPS = Not Analyzed Positive Stop
*No asbestos was detected. However, due to the uncertainty with existing testing techniques for vermiculite insulation, EPA and ATSDR
strongly recommend that all vermiculite insulation be assumed to contain asbestos. Therefore, Techtron Engineering recommends that this
material be assumed to contain asbestos in quantities less than one percent.
Reporting Limit: 1%. Some samples reported as NAFD may contain asbestos fibers in quantities below 1%. Detection limits are dependent upon the sample size, matrix, and any
interferences that may be present in the sample. Point counting is recommended for samples that require more precise quantification when samples contain low volumes of asbestos
fibers (i.e. 1-5%). Results are based on field sampling information provided by the client and are only valid for samples tested. Samples are stored for 30 days unless other
arrangements are made by the client. Samples received in good condition unless otherwise noted. This report shall not be repr oduced except in full, without the written approval of
