Historical Standard: ASTM D4746-98 Standard Test Method for Determination of Quinoline Insolubles (QI) in Tar and Pitch by Pressure Filtration
SUPERSEDED (see Active link, below)
ASTM D4746
1. Scope
1.1 This test method covers the determination of the quinoline-insoluble matter (QI) in tar and pitch by pressure filtration and gives results comparable to those obtained by Method D 2318.
1.2 Since this test method is empirical, strict adherence to all details of the procedure is necessary.
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 7.
