27 July 1995
Test No. 102: Melting Point/ Melting Range OECD
This Test Guidelines describes several methods and devices to determine the temperature or temperature range of the phase transition from the solid to the liquid state or from the liquid to the solid state.
27 July 1995
Test No. 103: Boiling Point OECD
This Test Guideline describes methods to determine the boiling point of test substances. The boiling point of a liquid is defined as the temperature (in K) at which the vapour pressure equals the standard atmospheric pressure 101.325 kPa.

Test No. 105: Water Solubility OECD
This Test Guideline describes methods to determine the water solubility of test substances.
27 July 1995
Test No. 107: Partition Coefficient (n-octanol/water): Shake Flask Method OECD
This Test Guideline describes a method to determine experimentally Pow values in the range log Pow between -2 and 4 (occasionally up to 5). This method can not be used with surface-active materials.
27 July 1995
Test No. 109: Density of Liquids and Solids OECD
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.
27 July 1995
Test No. 115: Surface Tension of Aqueous Solutions OECD
This Test Guideline describes methods to determine the surface tension (in N/m) of aqueous solutions. The methods are based on the measurement of the force which it is necessary to exert vertically on a stirrup or ring...

Test No. 101: UV-VIS Absorption Spectra OECD
This Test Guideline describes the determining of the ultraviolet-visible (UV-VIS) absorption spectrum of a chemical compound to have some indication of the wavelengths at which the compounds may be susceptible to photochemical degradation.
12 May 1981
Test No. 108: Complex Formation Ability in Water OECD
This Test Guideline describes the polarographic method. The ability of a substance to form complexes with metals can be assessed by means of polarographic techniques which allow the determination of stability constants for some complexes.
12 May 1981
Test No. 110: Particle Size Distribution/ Fibre Length and Diameter Distributions OECD
This Test Guideline describes two methods. These tests are applicable only to water insoluble (solubility
12 May 1981
Test No. 112: Dissociation Constants in Water OECD
