The U.S. Environmental Protection Agency (EPA) has established quality assurance procedures for air pollution measurement systems. Among the areas of EPA's concern is the accuracy of compressed gas standards used for calibration and audits of continuous emission monitoring systems and ambient air quality analyzers. EPA's regulations specify that the certified values for these standards be traceable to National Institute of Standards and Technology (NIST) Standard Reference Materials (SRMs) or to NIST/EPA-approved Certified Reference Materials via two traceability protocols. The results of an audit of all commercial gas manufacturers of sulfur dioxide, nitric oxide and carbon monoxide at ppm concentration levels are provided, as well as showing how each gas manufacturer complied with the reporting requirements to the customers as stated in the traceability protocols.
