<br /> <br /> <br /> <br />NAFD = No Asbestos Fibers Detected <br />NAPS = Not Analyzed Positive Stop <br /> <br />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 <br />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 <br />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 sto red for 30 days unless <br />other arrangements are made by the client. Samples received in good condition unless otherwise noted. This report shall not b e reproduced except in full, without the written <br />approval of Techtron Engineering.
