Purpose: NIST is collecting this information to permit the inventory, order, and purchase of materials and informatic reference materials by the public. Subsequent payment information is collected to enable supporting financial activities (e.g., invoicing, tracking, payment).

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

Standard Reference Materials® Description: 1) NIST supports accurate and compatible measurements by certifying and providing over 1100 Standard Reference 

The main purpose of standard reference materials is to provide a well characterized material with a measured value and its associated uncertainty for some 

As part of their main mission, NIST certifies and provides standard reference materials (SRM). SRMs are used to perform instrument calibrations, verify accuracy of specific measurements and to support development of new measurement methods. SRMs are also used to support measurement traceability in the United States.

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].
