It is commonly called the viscosity of the liquid. B Based on less than 30 degrees of freedom.

ASTM D Standard

Caution should be taken when handling mercury and asfm containing products. View as Grid List. Abd ElrhmanSanaa A. Work Item s – proposed revisions of this standard.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Factors controlling heat exchange between the human body and its. Rinse the ice with distilled water and shave or crush into small pieces, avoiding direct contact with the hands or any chemically unclean objects.

The practice of completely submerging the thermometer is not recommended. MS Word file of most equations that come up in Physics Box 16, State College, Pa. The viscometer bath has a drain to remove the bath content. Dry the tube by passing a slow stream of filtered dried air through the capillary for 2 min, or until the last trace of solvent is removed.

Pour sample through tube N to a point just above filling mark G; allow the sample to flow freely through capillary R, taking care asfm the liquid column remains unbroken, until the lower meniscus is about 5 mm f2170 the filling mark H and then arrest its flow by closing the timing tube with a cork or rubber stopper in tube L.

For the LantzZeitfuchs viscometer, apply slight vacuum to tube M or pressure to tube N with tube K closed until the lower meniscus is opposite the lower timing mark E; allow the sample to flow d21170 gravity. Current edition approved Oct.

Kinematic Viscosity ASTM D2170

Introduce sufficient sample through tube N to completely asym bulb D, overflowing slightly into overflow bulb K. The time is measured for a fixed volume of liquid to flow under gravity through the capillary of a calibrated viscometer under a reproducible driving head and at a closely controlled and known temperature inside a viscosity bath. See Annex A1 for the method of calculation.

Combining values from the two systems may result in non-conformance with the standard.

Draw liquid through tube N, filling bulb D to fill mark G. D viscometer calibration factor.

Kinematic Viscosity ASTM D

See the detailed descriptions of viscometers in Annex A2 for instructions for using the type viscometer selected. When thermometers are completely submerged, corrections for each individual thermometer based on calibration under conditions of complete submergence asfm be determined and applied.

The TV has a cover with seven openings and lids. Why is the kinematic viscosity of asphalts bitumens important to know? A number in parentheses indicates the year of last reapproval. Additional operating instructions for the reverseflow viscometers are outlined in A2. If the ratio is not constant, the liquid is non-Newtonian. Successive readings taken at X1. Discard any cloudy or unsound portions.

Link to Active This link will always route to the current Active version of the standard. The values given in column 3 are the limits that should not be exceeded by the difference between the results asmt two properly conducted tests. Preparation of Sample 7.

Physical and Chemical Properties. A superscript epsilon e indicates an editorial change since the last revision or reapproval. C2 5 the calibration constant in the testing laboratory, C 1 5 the calibration constant in the calibrating laboratory, 5 the acceleration of gravity at the testing laboratory, g2 and 5 the acceleration of gravity at the calibrating laborag1 tory.

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. The flash point is determined in accordance with Test Method D Practical 4 Effect of concentration on viscosity Name: On the Identification of Technology Shocks: The TV and TV have a bath volume of 20 and 40 litres respectively.

Kinematic viscosity, cSt 5 Ct 1 where: The aging properties of polymer modified asphalts were examined using thin film oven test TFOT. Firm supports for the viscometer shall be provided, or the viscometer may be an integral part of the bath. These openings accommodate glass capillary viscometers in viscometer holders. Co 5 viscometer constant when filled and tested at the same temperature, T 5 temperature, F 5 temperature dependence factor see A3. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

For the Zeitfuchs Cross-Arm viscometer, apply slight vacuum to tube N or pressure to tube L to cause the meniscus to move over the siphon tube and about 30 mm below the level of tube D in capillary R; gravity flow is thus initiated.
