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).
