Standard Test Method for Softening Point of Pitches (Cube-in-Water Method)

Importancia y uso:

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

5.2 This test is useful in determining the consistency of pitch as one element in establishing the uniformity of shipments or sources of supply.
