This method measures the mass concentration of any non-volatile respirable dust. Besides inert dusts, the method has been recommended for respirable coal dust. The method is biased in light of the recently adopted international definition of respirable dust (e.g., ˜+7% bias for non-diesel, coal mine dust). The working range is 0.5 to 10 mg/m³ for a 200-L air sample. NOTE: This method is based on and replaces Sampling Data Sheet #29.02.

* The analytes and detection limits listed for each method represent the typical detection limits and analytes reported for that particular method. Keep in mind that analyte lists may vary from laboratory to laboratory. Detection limits may also vary from lab to lab and are dependent upon the sample size, matrix, and any interferences that may be present in the sample.
