Metrological traceability of measurement results in chemistry: Concepts and implementation (IUPAC Technical Report)

Autor: D. Brynn Hibbert, Paul De Bièvre, Ales Fajgelj, René Dybkaer

Publikováno v: Pure and Applied Chemistry. 83:1873-1935

This IUPAC study aims at formulating recommendations concerning the metrological traceability of a measurement result in chemistry. It is intended to provide the chemical measurement community with a consistent view of the creation, meaning, and role

CCQM owes chemists a description of the concept ‘amount of substance’

Autor: Paul De Bièvre

Publikováno v: Accreditation and Quality Assurance. 19:323-325

CCQM, the ‘Consultative Committee on amount of substance—metrology in chemistry’ to the International Committee for Weights and Measures (CIPM), is being renamed ‘CC on amount of substance—metrology in chemistry and biology’. This seems t
