Use of the National Bureau of Standards Standard Reference Gases in Mobile Source Emissions Testing

Source

The Mobile Source Air Pollution Control (MSAPC) program has developed a system of primary gas standards which permits commercial gas blends to be named within 2 percent of true value and a computer program which documents the path and traceability relationship of each gas to the National Bureau of Standards (NBS) standard reference material (SRM).

The MSAPC program incorporates gravimetric gas blending as a primary means to verify and extrapolate the work of the NBS. These blends comprise the reference points for a two-point linear interpolation procedure for gas analysis and correlation. The advantages and limitations of this procedure are outlined and quantified.
