Sample collection and containers provided by the client, acceptable bottle blank level is defined as <=0.01MFL>10um ND=None Detected. Fiber counting data will be reported as follows; No Fibers detected: The value will be reported as less than 389% of the conceniration equivalent to one fiber. i to 4 fibers; The result will be reported as less than the corresponding upper 95% confidence limit (Poisson), 5 to 30 fibers: Mean and 95% confidence intervals will be reported on the basis of the Poisson assumption. When more than 30 fibers are counted, both the Gaussian 55% confidence interval and the Poisson 95% confidence interval wii: be calculated The -arge of these two intervals will be selected for data reporting. iVhen the Gaussian 95% confidence interval is selected for data reporting, the Poisson will also be noted This report may rot ne reproduced, except in full, without written peAissionfcy EMSL Analytical, Inc
