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 ...

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 ...

This Test Guideline (TG) describes a harmonised procedure to determine the Volume Specific Surface Area (VSSA) of powdered solid manufactured nanomaterials (MNs).

This Test Guideline describes methods to determine the water solubility of test substances. The water solubility of a substance is the saturation mass concentration of the substance in water at a given temperature. This guideline addresses the ...

This Test Guideline describes a method to determine the fat solubility of solid and liquid substances. The fat solubility of a substance is one of the data for evaluating the storage of lipid soluble materials in biological tissue. This test method ...

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 ...

This Test Guideline describes a laboratory test method to assess abiotic hydrolytic transformations of chemicals in aquatic systems at pH values normally found in the environment (pH 4 – 9). This Guideline is designed as a tiered approach; each tier ...
