ASTM International recently published a new standard that provides a method for making valid exposure measurements for crystalline silica exposures in industry. According to ASTM, the Standard Test Method for Measurement of Respirable Crystalline Silica in Workplace Air by Infrared Spectrometry “specifies a generic sampling and analytical method for measurement of the mass concentration of respirable crystalline silica in workplace air using infrared spectrometric methods.” The standard is intended for use by agencies concerned with health and safety at work; industrial hygienists and other public health professionals; analytical laboratories; and industrial users of silica-containing products and their workers.
