Monetary aggregates are the money circulating in an economy to satisfy its current monetary needs. There are two indicators for monetary aggregates collected by the OECD: "narrow money" (M1); a means of exchange and "broad money" (M3); a way to store value. Monetary aggregates are measured as a...

This Test Guideline lists methods for determining the density of liquids and solids, giving only a very succinct description of them. The density of a substance is the quotient of its mass and its volume and is expressed in kg/m3. Several methods are for liquid substance only: hydrometer,...

This Test Guideline describes methods to measure the viscosity of liquids. The methods listed are appropriate in principle for the investigation of Newtonian liquids. The measurement of non-Newtonian liquids is only possible with the rotational viscometer. Viscosity measurements are carried out...

This Test Guideline lists methods for determining the density of liquids and solids, giving only a succinct description of them. The density of a substance is the quotient of its mass and its volume and is expressed in SI units as kg/m3 at a specified temperature. Several methods are for liquid...
