XX Centrifuge Extractor, Filterless Use in the extraction of mineral fines from bitumen-laden solvents obtained from standard asphalt extraction tests. This standard has been approved for use by agencies of the Department of Defense. These motorized extractors have accurate, dependable electronic solid state speed control; rotation speed adjusts up and down. Transfer the extraction to a mL graduate. Stop the vacuum when all solvent has been removed. satm
Centrifuge Extractors, ASTM D
Cool the container and redetermine the mass immediately. Place the bowl containing the test portion and the solvent in the extraction apparatus.
Again, record the mass. Take this test specimen from the remaining sample of the mixture immediately after obtaining the extraction test specimen.

Size px x x x x Active view current version of standard. Add approximately mL of methylene chloride and stir until the asphalt is visually in solution. Sco Scope pe 1. If trichloroethylene or normal Propyl Bromide is used as the extraction solvent, the preliminary drying on a steam bath may be omitted.
Specific hazards are atsm in Section 7. Note 1—The results obtained by these test methods may be affected by the r2172 of the material tested, with older samples tending to yield slightly lower bitumen content.
Remove the ring and brush the clinging aggregate into the drying pan. Allow aetm machine to stop, add mL of trichloroethylene, normal Propyl Bromide, or methylene chloride and repeat the procedure. Best quantitative results are obtained when the test is made on mixtures and pavements shortly after their preparation. It is the responsibility of the user of this standard to establish appropriate safety asmt health practices and determine the applicability of regulatory limitations prior to use.
The metal used in fabricating the frames shall be essentially inactive to the solvents used in the test method. Once this is accomplished the remaining aggregates are weighed and graded. After all the extract has passed through the centrifuge, wash the feed mechanism with centrifuge still running with several increments of clean solvent, allowing each increment aastm run through the centrifuge until the effluent is essentially colorless.
Please fill this form, we will try to respond as soon as possible. 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.
Best quantitative results are obtained when the test is made on mixtures and pavements shortly after their preparation. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
A number in parentheses indicates the year of last reapproval. In this case, it is not necessary to f2172 the extract from the extraction cylinder to a graduated cylinder. Link to Active This link will always route to the current Active version of the standard.
Determine the mass of an ignition dish.
We are a non-profit group that run this website to share documents. Evaporate to dryness on a steam bath or hot plate, except use a steam bath when the solvent is benzene.
Clean the outside with fresh solvent. Combining values from the two systems may result in non-conformance with the standard.
Best quantitative results are obtained when the test is made on mixtures and pavements shortly after their preparation.
The last approved version of this historical standard is referenced on www. The apparatus preferably shall be provided with explosion-proof features and installed in a hood or an effective surface exhaust system to provide ventilation. When sufficiently cool, pour mL of denatured alcohol over the specimen. Start the vacuum xstm and let it run until the pad formed by the diatomaceous silica is surface dry and begins to crack slightly. Optional small-mouth graduate, mL capacity. Originally approved in
