Quantitative transmission electron microscopy is currently the only method that can be used to determine if this material can be considered or treated as non-asbestos-containing * Samples will be stored for ninety (90) davs and then returned to the client upon request * The results relate onlv to the items calibrated or tested. * The certificate of report shall not be recroduced without the written approval of the laboratory. kV The reoort must not be used bv the client to claim endorsement by NVLAP or any agency of the US Governrp^t. ,\ YS-DOH ELAP « 11273 NIST-NVLAP # 102047 AIHA #: 100269
