Collaborative Tests of Two Methods for Determining Free Silica in Airborne Dust

• Description:
  A collaborative study of the determination of free silica in airborne dust was conducted in which an x-ray diffraction (XRD) and an infrared (IR) method were examined and compared. The study's objectives were to obtain information on the precision and bias of these methods for monitoring worker exposure. Fifteen laboratories participated in each test, in a program structured to assess both sampling and analytical errors and to determine the analytical error sources. Samples for the collaborative tests were collected from aerosols prepared in a specially adapted laboratory generation system. Both methods were found to be similar in their resultant percent relative standard and in their ruggedness. Both methods were found to be unbiased and gave similar results for coal mine dust samples.
