17、Hot Plate, electric, approximately 200 mm 8 in. indiameter, with a three-heat switch, rated at 1200 W at the highheat setting and 500 to 600 W at the medium heat setting.7. Sampling7.1 Sample the material in accordance with Practice D140/D140M.8. Preparation of Apparatus8.1 Clean the viscometer thor

18、oughly 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; all workingareas shall be efficiently hooded and kept free of sparks andopen flames. If the viscometer i

19、s 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 2The viscometer may be kept clean by filling with cylinder oilimmediately after each test and allowing the

20、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, draining and cleaning with xylene just beforeeach test.8.2 Set up the viscometer and bath in an area where theyw

21、ill not be exposed to drafts or rapid changes in airtemperature, and dust or vapors that might contaminate asample.8.3 Place the receiving flask beneath the viscometer so thatthe graduation mark on the flask is from 100 to 130 mm 4 to5 in. below the bottom of the viscometer tube, and so that thestre

22、am 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 temperature:8.4.1 Use SAE 40 grade oil for test temperatures up to149C 300F.8.4.2 For temperatures above 149C 300F

23、, use a cylinderoil having a viscosity of approximately 175 to 185 SUS at98.9C 210F, and a minimum flash point of 300C 572Fwhen tested in accordance with Test Method D92.8.4.3 Change the bath medium periodically, and clean theoutside walls of the tubes to remove any carbon deposits.8.5 Provide adequ

24、ate 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 temperature.9. Calibration and Standardization9.1 Calibrate the Saybolt Furol viscometer at periodic inter-vals in accordance with

25、Test Method D88, Section 9, andcalculate the correction factor for the viscometer.9.2 Do not use viscometers or orifices requiring correctionsgreater than 61%.10.

28、ork stopper, having a cord attached 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 g

29、allery of theviscometer.10.4 Preheat a 0.5-kg 1-lb sample in a 500-mL 16-ozseamless tin box of the deep type on the electric hot plate toabout 10 to 15C 18 to 27F above the selected testtemperature.10.4.1 Use the medium-temperature setting on the hot platefor the first half hour, and the high-temper

30、ature setting for theremainder of the heating period. Avoid overheating initiallybecause this might cause some oxidation of the sample andalter its viscosity.10.4.2 Stir the sample occasionally during the early stagesof heating, but employ continuous stirring for the last 28C50F.10.4.3 Complete the

31、preheating in2horless, and proceedimmediately with the viscosity determination. Reheating ofany sample shall not be permitted.10.5 Preheat the 850-m No. 20 sieve to the selected testtemperature, and pour the heated sample through the sievedirectly into the viscometer until the level is just above th

32、eoverflow rim.NOTE 3Just enough sample should overflow so that later removal ofthe displacement ring will cause the excess to flow into the gallery withoutcompletely filling it.10.6 Place the cover on the viscometer over the displace-ment ring, and insert the appropriate viscosity thermometerequippe

33、d with the thermometer support through the hole in thecenter of the cover.10.7 Stir the sample in the viscometer continuously with thethermometer, using 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

34、sample temperature remains constant within0.3C 0.5F of the test temperature during 1 min of continu-ous stirring, withdraw the thermometer and remove the coverfrom the viscometer. Immediately remove the displacementring, check to be sure that the excess sample in the gallery isbelow the level of the

35、 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 the viscometer using theattached cord, and start the timer at the same instant. Theelapsed time from filling the viscometer to snapping the corkshall not

36、 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 the nearest 0.1 or 0.2 s.11. Calculation and Report11.1 Multiply the efflux time by the correction factor for theviscometer determined in 9.1.11.2 Report
