Standard Test Methods for
Separation of Asphalt into Four Fractions1
This standard is issued under the fixed designation D 4124; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 These test methods cover the separation of four defined
fractions from petroleum asphalts. The four fractions are
defined as saturates, naphthene aromatics, polar aromatics, and
nC7-asphaltenes. These methods can also be used to isolate
saturates, naphthene aromatics, and polar aromatics from
distillate products such as vacuum gas oils, lubricating oils, and
cycle stocks. These distillate products usually do not contain
asphaltenes.
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. Specific precautionary statements are given in Section 8 and 15.
