Th
34、e overall uncertainty is expressed as a percentage that combines bias and precision. Fora given statistical confidence level (N), the overall percent uncertainty may be calculated using the following formula:OU5S?X 2XREF?1NXREF D3100 (1)where:X = mean value of results of a number (n) of repeated mea
35、surements,Xref = true or accepted reference value of measurement result, = standard deviation of a number (n) of repeated measurements, andN = number of standard deviations from the mean. N generally takes value of 1, 2 or 3 corresponding to 68 %, 95 %, and 99 %confidence intervals, respectively. Si
36、nce the desired confidence interval is often 90 % or more, a value of 1.7 or highertypically is used for N.For example, given a precision and bias of 610 %, and a desired confidence interval of 95 %, the overall uncertainty using Eq1 will be 30 %.3.2.10 permissible exposure limit (PEL), nthe OSHA-ma
