Gas
Mixture NTRM Producer Information
An NTRM® (NIST Traceable Reference Material) is a commercially
produced reference material with a well-defined traceability linkage to existing
NIST standards. This traceability linkage is established via criteria and protocols
defined by NIST which include the NIST analysis of at least 10% of a Gas Mixture
NTRM® batch. Commercial producers may affix the NTRM®
certification mark provided by NIST to materials produced according to these criteria
and protocols. A NIST NTRM® may be recognized by a regulatory authority
as being equivalent to a Certified Reference Material (CRM). For additional information,
see Guenther, F.R., Dorko, W.D., Miller, W.R., Rhoderick, G.C. The NIST NTRM®
Program for Gas Standards, NIST Spec. Publ. 260-126 (1997). Contact can be made
