Historical Standard: Standard Test Method for Apparent Viscosity of Asphalt Emulsion Residues and Non-Newtonian Bitumens by Vacuum Capillary Viscometer (Withdrawn 2017)<\/h4>\n
\n

ASTM D4957<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method describes procedures primarily designed to determine the apparent viscosities of residues obtained by distilling asphalt emulsions according to Test Method D 6997`<\/span>. It is also recommended for use on non-Newtonian asphalts at any temperature within the capability of the apparatus. This test method is useful in characterizing rheological properties of non-Newtonian bitumens as a function of shear rate under the conditions of the test method. This test is run in straight open-end tube viscometers, normally at 60\u00b0<\/span>C (140\u00b0<\/span>F), but is suitable for use at other temperatures. It is applicable over the range from 5 to 50 000 Pa\u00b7<\/span>s (50 to 500 000 P).<\/p>\n

Note<\/span> 1\u2014The precision for this test method is based on determinations made at 60\u00b0<\/span>C (140\u00b0<\/span>F).<\/p>\n

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.<\/span><\/p>\n
