* Analysis of samples is performed by PoK irized Light Microscopy (PLM) - Point Counting Method (EPA 600/M4-82-020) * Analytical equipments: StereoUuiocular microscope (MEIJI EMT-Serial # 25930), Polarized Light Microscope (MEIJI ML-POL-Serial # 88034) * PLM is not consistently reliable in detecting asbestos in floor coverings and similar non-friable organically bound materials. 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 tc 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. w NYS-DOH ELAP # 11273 NIST-NVLAP# 102047 AIHA #: 100269
