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...

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

This Test Guideline describes the procedure for the electronic determination of pH of an undiluted aqueous solution or dispersion, the pH of a dilution of a solution or dispersion in water, or the pH of a chemical diluted to end-use concentration. It also describes procedures to determine acid...

Tax wedge is defined as the ratio between the amount of taxes paid by an average single worker (a single person at 100% of average earnings) without children and the corresponding total labour cost for the employer. The average tax wedge measures the extent to which tax on labour income...

Tax on property is defined as recurrent and non-recurrent taxes on the use, ownership or transfer of property. These include taxes on immovable property or net wealth, taxes on the change of ownership of property through inheritance or gift and taxes on financial and capital transactions. This...
