A statistical analysis of asbestos fiber counting in the laboratory and industrial environment.
The reproducibility of standard fiber counts in the laboratory and four industrial plants is discussed in detail. Under field conditions the standard deviation of the results varied between 0.4-1.2 f/ml. Under ideal laboratory conditions the standard deviations of the counts were approximately 0.2 f/ml. It is concluded that the standard method is sufficiently precise for industrial measurements.
