| Significance and Use | ||||||||||||
|
4.1?This test method is a measure of the solubility of asphalt in trichloroethylene or toluene solvent. The portion that is soluble in the solvent represents the active cementing constituents. Note 2:?The quality of the results produced by this standard
are dependent on the competence of the personnel performing the
procedure and the capability, calibration, and maintenance of the
equipment used. Agencies that meet the criteria of Specification
D3666 are generally
considered capable of competent and objective testing, sampling,
inspection, etc. Users of this standard are cautioned that
compliance with Specification D3666 alone does not completely ensure
reliable results. Reliable results depend on many factors;
following the suggestions of Specification D3666 or some similar acceptable
guideline provides a means of evaluating and controlling some of
these factors.

1.1?This test method covers the determination of the degree of solubility in trichloroethylene or toluene of asphalt materials having little or no mineral matter. Note 1:?This method is not applicable to tars and their
distillation residues or highly cracked petroleum products. For
methods covering tars, pitches, and other highly cracked petroleum
products, and the use of other solvents, see Test Methods
D4, D2318, and D2764.
1.2?The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3?The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the 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. |
