Abstract
Characteristics of cleavage fragments and fibers of tremolite (60649538) were compared. Fragments and ground fibers from blocky, acicular, fibrous and asbestos varieties of tremolite were examined. The different varieties of tremolite possessed varying physical characteristics, and cleavage fragments differed from fiber samples of the same material. The authors conclude that the aspect ratio of regulatory particles should be increased from 3:1 to at least 10:1. Fiber counting and reporting methods should include aspect ratios and minimum diameter measurements. The variety of tremolite should be specified and concentrations of other varieties present in the sample should be provided.
