Standard Test Method for Relative Density of Solid Pitch and Asphalt (Displacement Method) — 2 стр.
Значение и использование

5.1 This test method is useful in characterizing pitches and asphalts as one element in establishing uniformity of shipments and sources of supply.

Область применения

1.1 This test method covers the determination of relative density by water displacement of hard pitches and asphalts with softening points above 70 °C.

1.2 The relative density of hard pitch and asphalt shall be determined, whenever possible, on homogeneous natural fragments free of cracks. The use of cast cubes is not recommended due to the difficulty of avoiding incorporation of air bubbles.

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

1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
