ASTM D3104 Standard Test Method for Softening Point of Pitches (Mettler Softening Point Method)
1. Scope
1.1 This test method covers the determination of the softening point of pitches having softening points in the range from 50 °C to 180 °C by this test method, and gives results comparable to those obtained by Test Method D2319 above 80 °C (176 °F).
1.2 The values stated in SI units are to be regarded as the 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.
