This report explains how calibration gases will be used in Inspection and Maintenance (I/M) programs, and identifies the problems states may have in obtaining accurate gases. A Recommended Analysis Practice for gas manufacturers to use when naming I/M calibration gases is presented. States are encouraged to procure gases named according to this Recommended Practice for their own use, and to require licensed inspection stations to procure them to ensure that they are obtaining accurate calibration gases which meet the terms of the Emission Performance Warranty (207 (b)), and to improve the general quality of their Inspection and Maintenance programs.
