Certification: What It Means for Inhomogeneity and Reference Materials

Kennedy, WR
Birmingham, AL

Abstract

A comparison is made between concepts Americans and foreigners have of the term certification. The paper discusses the requirements for a Standard Reference Material (SRM) Certificate and a Certified Reference Material (CRM) Certificate, and how what appears on the Certificate affects our concepts of homogeneity and inhomogeneity. Also discussed is why who issues a Certificate sometimes is more important than what is on the Certificate. The paper is a challenge to standardize SRM and CRM Certificates.
