Standard Test Method for Softening Point of Pitch (Cube-in-Air Method)

Importancia y uso:

4.1 Pitch does not go through a solid-liquid phase change when heated and therefore does not have a true melting point. As the temperature is raised, pitch softens and becomes less viscous. The softening point is arbitrarily defined and must be determined by a closely controlled method that must be carefully followed if test results are to be reproducible.

4.2 This test method is useful in determining the consistency of pitch as one element in establishing the uniformity of shipments and sources of supply.
