    Significance and Use

    This test method is intended to determine the melting point of all normal animal and vegetable fats.

    The natural fats and oils, that is, those of animal and vegetable origin, are mixtures of glycerides and other substances and consist of a number of components. They do not exhibit either a definite or sharp melting point. Fats pass through a stage of gradual softening before they become completely liquid. The melting point then shall be defined by the specific conditions of the method by which it is determined and, in this case, it shall be the temperature at which the sample becomes perfectly clear and liquid.

    1. Scope

    1.1 This test method is intended to determine the melting point of all normal animal and vegetable fats and oils. This test method was derived from ALCA H-16.

    1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
