The viscosity value isreported in Saybolt Furol seconds, abbreviated SFS, at aspecified temperature.4.

7、 Summary of Test Method4.1 The efflux time in seconds of 60 mL of sample, flowingthrough a calibrated orifice, is measured under carefullycontrolled conditions. The time is corrected by an orifice factorand reported as the viscosity of the sample at that temperature.5. Significance and Use5.1 This t

8、est method is useful in characterizing certainbituminous materials, as one element in establishing unifor-mity of shipments and sources of supply.5.2 This test method is an extension of Test Method D 88.6. Apparatus6.1 Saybolt Furol Viscometer and Bath, as shown anddescribed in Test Method D 88, Fig

9、. 1 and Annex 1. Anexternal heater may also be used, but if so, it shall be more than51 mm (2 in.) from the viscometer. An aluminum-block,constant-temperature bath is also acceptable, and no stirringdevice is required with this type of bath.6.2 Displacement Ring, as shown in Fig. 1, constructed ofth

10、e same corrosion-resistant metal as the viscometer.6.3 CoverA metal cover for the viscometer, cylindricalwith a flat top, approximately 57 mm (214 in.) in diameter and7mm(14 in.) deep (Note 1). One hole slightly larger than thediameter of a viscosity thermometer shall be drilled in thecenter of the

11、cover, and two smaller holes to permit the verticalrods of the displacement ring to pass through the cover.NOTE 1The cover of a 90-mL (3-oz) Gill-style ointment box fulfillsthese requirements.6.4 Thermometer Support, as shown in Test Method D 88,Fig. 3.6.5 Saybolt Viscosity Thermometers, as listed i

17、le the material in accordance with Practice D 140.8. Preparation of Apparatus8.1 Clean the viscometer thoroughly with xylene, removeall solvent from the viscometer and its gallery, and dry well.Clean the displacement ring and receiving flask in the samemanner. Xylene is a toxic and flammable solvent

18、; all workingareas shall be efficiently hooded and kept free of sparks andopen flames. If the viscometer is hot, vaporization of xylenecan be reduced by filling the tube rapidly and immediatelyallowing it to flow out through the orifice. A wooden toothpickmay be useful in cleaning the orifice.NOTE 2

19、The viscometer may be kept clean by filling with cylinder oilimmediately after each test and allowing the oil to remain in theviscometer for several minutes before draining and cleaning with xyleneas described above. If desired, the viscometer may be kept filled withcylinder oil between runs, draini

20、ng and cleaning with xylene just beforeeach test.8.2 Set up the viscometer and bath in an area where theywill not be exposed to drafts or rapid changes in air tempera-ture, and dust or vapors that might contaminate a sample.8.3 Place the receiving flask beneath the viscometer so thatthe graduation m

21、ark on the flask is from 100 to 130 mm (4 to5 in.) below the bottom of the viscometer tube, and so that thestream of liquid will just touch the neck of the flask.8.4 Fill the bath to at least 6 mm (14 in.) above the overflowrim of the viscometer with an appropriate bath medium for theselected test t

22、emperature:8.4.1 Use SAE 40 grade oil for test temperatures up to149C (300F).8.4.2 For temperatures above 149C (300F), use a cylinderoil having a viscosity of approximately 175 to 185 SUS at98.9C (210F), and a minimum flash point of 300C (572F)when tested in accordance with Test Method D 92.8.4.3 Ch

23、ange the bath medium periodically, and clean theoutside walls of the tubes to remove any carbon deposits.8.5 Provide adequate stirring and thermal control for thebath so that the temperature of a test sample in the viscometerwill not vary more than 0.3C (0.5F) after reaching theselected test tempera

24、ture.9. Calibration and Standardization9.1 Calibrate the Saybolt Furol viscometer at periodic inter-vals in accordance with Test Method D 88, Section 9, andcalculate the correction factor for the viscometer.9.2 Do not use viscometers or orifices requiring correctionsgreater than 61%.10. Procedure10.

25、1 Establish and control the bath temperature at theselected test temperature.10.1.1 Standard test temperatures for measuring SayboltFurol viscosities of bituminous materials are 121, 135, 149,163, 177, 204, and 232C (250, 275, 300, 325, 350, 400, and450F).10.2 Insert a cork stopper, having a cord at

26、tached for itseasy removal, into the air chamber at the bottom of theviscometer. The cork shall fit tightly enough to prevent theescape of air, as evidenced by the absence of oil on the corkwhen it is withdrawn later as described.10.3 Place the displacement ring in the gallery of theviscometer.10.4

27、Preheat a 0.5-kg (1-lb) sample in a 500-mL (16-oz)seamless tin box of the deep type on the electric hot plate toabout 10 to 15C (18 to 27F) above the selected testtemperature.(Material: Corrosion-resistant metal.)FIG. 1 Displacement RingTABLE 1 ASTM Saybolt Viscosity ThermometersStandard TestTempera

Avoid overheating initiallybecause this might cause some oxidation of the sample andalter its viscos

30、ity.10.4.2 Stir the sample occasionally during the early stagesof heating, but employ continuous stirring for the last 28C(50F).10.4.3 Complete the preheating in2horless, and proceedimmediately with the viscosity determination. Reheating ofany sample shall not be permitted.10.5 Preheat the 850-m (No

31、. 20) sieve to the selected testtemperature, and pour the heated sample through the sievedirectly into the viscometer until the level is just above theoverflow rim.NOTE 3Just enough sample should overflow so that later removal ofthe displacement ring will cause the excess to flow into the gallery wi

32、thoutcompletely filling it.10.6 Place the cover on the viscometer over the displace-ment ring, and insert the appropriate viscosity thermometerequipped with the thermometer support through the hole in thecenter of the cover.10.7 Stir the sample in the viscometer continuously with thethermometer, usi

33、ng a circular motion at 30 to 50 rpm in ahorizontal plane to avoid whipping air into the sample. Takecare to avoid striking the orifice.10.8 When the sample temperature remains constant within0.3C (0.5F) of the test temperature during 1 min of continu-ous stirring, withdraw the thermometer and remov

34、e the coverfrom the viscometer. Immediately remove the displacementring, check to be sure that the excess sample in the gallery isbelow the level of the overflow rim, and replace the cover onthe viscometer.10.9 Check to be sure that the receiving flask is in properposition; then snap the cork from t

35、he viscometer using theattached cord, and start the timer at the same instant. Theelapsed time from filling the viscometer to snapping the corkshall not exceed 15 min.10.10 Stop the timer the instant the sample reaches thegraduation mark on the receiving flask. Record the efflux timein seconds to th
