in French: Comité consultatif pour la quantité de matière – métrologie en chimie
The CCQM was set up in 1993. Its name was modified slightly by the CIPM in 2001; previously it was called the Consultative Committee for Amount of Substance.

Present activities concern primary methods for measuring amount of substance, and international comparisons, establishment of international equivalence between national laboratories, and advice to the CIPM on matters concerned with metrology in chemistry.
