1111 34th Street <br /> Everett,WA 98201 <br /> Project Number:2017-0728 <br /> 3.0 LABORATORY INFORMATION <br /> Laboratory Analysis: Asbestos <br /> In accordance with 40 CFR Chapter 1 (1-1-87 edition) Part 763, Subpart F, Appendix A, asbestos <br /> samples are analyzed at NVL Labs using polarized light microscopy (PLM) with dispersion staining. If <br /> samples are not homogeneous, then sub-samples of the components are analyzed separately. All bulk <br /> samples are analyzed using EPA Method 600/R-93/116 with the following measurement uncertainties for <br /> reported % asbestos: 1%=0-3%, 5%k1-9%, 10%=5-15%, 20%=10-30%, 50%=40-60%. Only materials <br /> containing more than 1% total asbestos were classified as "asbestos-containing" based on EPA, state, <br /> and local regulations. <br /> Findings for samples containing more than one separable layer of materials are reported for each layer. <br /> The asbestos concentration in the sample is determined by visual estimation. <br /> NVL Labs is accredited by the National Institute of Standards and Technology (NIST)under the National <br /> Volunteer Laboratory Accreditation Program (NVLAP) program for bulk asbestos fiber analysis; NVLAP <br /> Lab Code 902063-0 <br /> Laboratory Analysis: Lead (Pb) <br /> Samples are analyzed for the presence of inorganic lead using atomic absorption spectroscopy(AAS) in <br /> accordance with EPA SW 846, method 7420 as revised 1986. This method reports results in milligrams <br /> per kilogram (mg/kg) or its equivalent, parts per million (ppm). <br /> Laboratory Accreditation <br /> Professional accreditations for NVL Laboratories, Inc. include the following: <br /> NVL Laboratories, Inc. is currently accredited by the National Institute of Standards and Technology <br /> (NIST) under the National Volunteer Laboratory Accreditation Program (NVLAP) program for bulk <br /> asbestos fiber analysis. <br /> NVLAP Lab Code 102063-0 <br /> NVL Laboratories, Inc. is approved by the American Industrial Hygiene Association (AIHA) Asbestos <br /> Analysts Registry (AAR) program for airborne asbestos fiber analysis. <br /> AAR Counter ID 7412 <br /> NVL Laboratories, Inc. is currently accredited by the American Industrial Hygiene Association (AIHA) <br /> under the Industrial Hygiene Laboratory Accreditation Program(IHLAP).
