<abstract displayLabel="Summary">Because of the need to completely and accurately size asbestos bulk samples for toxicity studies, a method was developed to classify asbestos fibres using enlarged micrographs originally produced on the scanning electron microscope (SEM). Individual fibre length and width measurements were performed on a computer-assisted, digitizing tablet. Seven distinct asbestos samples were classified including five chrysolite and to crocidolite samples. Statistical analyses showed good interfilter fibre size correlation for all types of asbestos</abstract>
