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

| 1. Scope | ||||||||||||||||
|
1.1 This test method covers the determination of the softening point of pitches below 176°F (80°C) by this method. Pitches of higher softening point should be tested by Test Method D2319 or Test Method D3104. 1.2 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. |
