Are Alcoa standards traceable to NIST?
A. Yes. NIST standard reference materials are used as part of the certification process. In many cases there are no NIST standards that correspond to the alloys we make. In those cases, the reference analytical methods, such as ICP, will always use NIST traceable solution standards. Traceability is further established through the use of certified and NIST traceable balances for all alloy charge production and analytical purposes. Note: Alcoa provides analysis for NIST standards as one part of NIST’s certification process.
