All bulk samples are analyzed using both EPA 600/R-93/116 and EPA 40 CFR Appendix E to Subpart E of Part 763 with the following measurement uncertainties for the reported%Asbestos(1%=0-3%, 5%=1-9%, 10%=5-15%,20%=10-30%,50%=40-60%).This report relates only to the items tested. If sample was not collected by NVL personnel,then the accuracy of the results is limited by the methodology and acuity of the sample collector This report shall not be reproduced except in full,without written approval of NVL Laboratories,Inc.
