New Test Method for Solubility of Asphalt Materials in N-propyl Bromide
1. Scope
1.1 This test method covers the determination of the degree of solubility in n-propyl bromide of asphalt materials. It is intended to be a replacement for method D 2042 specifying a solvent that, like trichloroethylene, is safe in that it has no flash point, and has similar solubilizing characteristics to trichloroethylene, but it is not considered to be an ozone depleter banned by the Kyoto Convention. Since a precision statement for this test method has not yet been developed, this test method should not be used for buying and selling purposes until the precision statement is available. NOTE 1This 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 D 4, D 2318, and D 2764. 1.2 The values stated in SI units are to be regarded as the 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precaution statements are given in Section 7.
