Overview - ISO 2977:1997 (Aniline point / Mixed aniline point)

ISO 2977:1997 specifies laboratory methods for determination of the aniline point and mixed aniline point of petroleum products and hydrocarbon solvents. The aniline point is defined as the minimum equilibrium solution temperature of equal volumes of aniline and sample; the mixed aniline point uses two volumes of aniline, one volume of sample and one volume of heptane. The standard covers five test methods (including a thin-film and automated method), sample preparation, apparatus, reagents and reporting requirements.
