ABSTRACT
Among the methods of quantifying asbestos contents in bulk asbestos samples, the most frequently used is the visual estimation. This paper presents a series of reference area percentage charts, featuring fibrous morphology to imitate asbestos fibers in a non-fibrous matrix. These charts can be used in the training of bulk asbestos analysts to better perform the calibrated visual estimation (CVE ) of the area percentage of asbestos fibers in bulk samples.
