Abstract

A program is described by which the concentration of commercially produced gas mixtures may be related to gaseous primary standards or measurement systems maintained by the National Institute of Standards and Technology (NIST). The gaseous mixtures, referred to as gas mixture NIST Traceable Reference Materials (NTRMs), must be similar in composition to NIST primary standards and the concentration of the certified component must be at, or bracketed by, primary standards. Although the NTRM gas mixtures are produced and distributed by commercial vendors, the concentration value assignment is made by NIST. The responsibilities of the producer and NIST are detailed along with recommended procedures the producer should follow during production and analysis of the mixtures. Procedures also are included for the maintenance of NTRM batches. Appendices are included for the preparation of NTRMs related to various Standard Reference Materials.
