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) days and then returned to the client upon request * The results relate only to the items calibrated or tested. * The certificate of report shall not be reproduced without the written approval of the laboratory. * The report must not be used by the client to claim endorsement by NVLAP or any agency of the US Government.
