Method for the Determination of Asbestos in Bulk Building Materials. (TestMethod)

摘要

Laboratories are now called upon to identify asbestos in a variety of bulkbuilding materials, including loose-fill insulations, acoustic and thermal sprays, pipe and boiler wraps, plasters, paints, flooring products, roofing materials and cementitious products. The diversity of bulk materials necessitates the use of several different methods of sample preparation and analysis. The report outlines the applicability of the various preparation and analysis methods to the broad spectrum of bulk building materials now being analyzed. The method demonstrated a capability for improving the precision and accuracy of analytical results. It contains significant revisions to procedures outlined in the Interim Method along with the addition of several new procedures.
