For convenience, the acronyms SRM, RM, and NTRM® are preferentially used in conjunction with the primary numerical identifiers (including renewal letters-if applicable), to describe all NIST reference materials. This website, the catalog and its supplement are no exceptions; thus, the reference materials described herein, are identified by their short titles (e.g., SRM 3102a) rather than by their long titles (e.g., Standard Reference Material 3102a). These short titles preserve the unique identifications of the materials involved and should be used in lieu of catalog numbers when ordering NIST reference materials. |
