nist certified reference material

A NIST certified value is a value for which NIST Support aspects involved in the issuance of this SRM were coordinated through the NIST Office of Reference Materials. The sediment was collected with the assistance of the New York District of the U.S. Army Corp of Engineers (ACENYD), who provided the expertise in the site selection, the ship

MIFAB’s copper piston operated water hammer arrestors are lead free and certified to ASSE 1010-1996 and ANSI A112.26.1M Standards, as well as IAPMO and IAPMO R&T certified. The non-freeze wall hydrant is certified lead free by the UPC authority. As standards change, it is important for us to be able to exceed those standards and provide our

The certified concentration for recombinant HSA was determined using a higher-order reference measurement procedure [ 4] calibrated with amino acid certified reference materials. The uncertainty provided value is an expanded uncertainty about the mean to cover the measurand, consistent with the ISO/JCGM Guide [ 3].
