SRMs 2294 through 2297 were produced in response to the U.S. EPA Final Rule on Reformulated Gas aimed at reducing the volatile organic compounds emitted from gasoline. SRMs 2294 through 2297 are certified for oxygenate, sulfur, benzene, and toluene, with reference values for olefins and aromatics. Each SRM unit is issued as a set of two sealed 20 mL ampoules.

PLEASE NOTE: The tables are presented to facilitate comparisons among a family of materials to help customers select the best SRM for their needs. For specific values and uncertainties, the certificate is the only official source.
