EPA Traceability Protocol for Assay and Certification of Gaseous Calibration Standards.

摘要

The U.S. Environmental Protection Agency (EPA) in Research Triangle Park, North Carolina has revised the 1997 version of its traceability protocol for the assay and certification of compressed gas and permeation-device calibration standards. The protocol allows producers of these standards, users of gaseous standards, and other analytical laboratories to establish traceability of EPA Protocol Gases to gaseous reference standards produced by the National Institute of Standards and Technology (NIST). Parts 50, 58, 60, 72, and 75 of Title 40 of the Code of Federal Regulations (CFR) require using Standard Reference Materials (SRMs) or gaseous standards traceable to SRMs for calibrating and auditing ambient air and stationary source pollutant monitoring systems.
