CONTAINED IN VOL. 11.07, 2015 Defines the procedure for determining the detection limit (DL) for measurements of fibers or structures using microscopy methods.

1.1 This practice presents the procedure for determining the detection limit (DL) for measurements of fibers or structures using microscopy methods.

1.2 This practice applies to samples of air that are analyzed either by phase contrast microscopy (PCM) or transmission electron microscopy (TEM), and samples of dust that are analyzed by TEM.

1.3 The microscopy methods entail counting asbestos structures and reporting the results as structures per cubic centimeter of air (str/cc) or fibers per cubic centimeter of air (f/cc) for air samples and structures per square centimeter of surface area (str/cm2) for dust samples.
