°C contained in the material. Constituent-specific adjustment factors (f
m25D) can be obtained by contacting the Waste and Chemical Processes Group, Office of Air Quality Planning and Standards, Research Triangle Park, NC 27711. Other test methods may be used if they meet the requirements specified in subd.
