CIPM Consultative Committee:

CCM – Consultative Committee for Mass and Related Quantities

CCM Working Groups:

		CCM Working Group on Density and Viscosity (CCM-WGDV)
		CCM Working Group on Fluid Flow (CCM-WGFF)
		CCM Working Group on Force and Torque (CCM-WGFT)
		CCM Working Group on Gravimetry (CCM-WGG)
		CCM Working Group on Hardness (CCM-WGH)
		CCM Working Group on Pressure and Vacuum (CCM-WGPV)
		CCM Working Group on Strategy and MRA coordination (CCM-WGS)
		CCM Working Group on the Dissemination of the kilogram (CCM-WGD-kg)
		CCM Working Group on the Realization of the kilogram (CCM-WGR-kg)
		CCM Task Group on the Phases for the Dissemination of the kilogram following redefinition (CCM-TGPfD-kg)

The CCM was set up in 1980.

Present activities concern matters related to the comparisons of mass standards with the international prototype of the kilogram, considerations affecting the definition and realization of the unit of mass, establishment of international equivalence between national laboratories for mass and a number of related quantities (density, pressure, force, fluid flow, viscosity, hardness, gravitational acceleration) and advice to the CIPM on these matters.
