The objective of this project is assure that certifications and uncertainty statements associated with NIST Standard Reference Materials are on a solid scientific foundation. SRMs are artifacts or chemical mixtures that are manufactured according to strict specifications, and are then certified by NIST for one or more physical or chemical properties of interest. SRMs are a primary vehicle used by NIST for disseminating measurement technology to industry. Staff of the Statistical Engineering Division (SED) collaborate with NIST scientists on:
- validation of the measurement method;
- design of a prototype;
- stability testing;
- characterization of measurement error; and
- certification and uncertainty analysis.
Statisticians advise on the design and analysis of experiments at all phases of this process.
