The values given in column 3 are the limits that should d21770 be exceeded by the difference between the results of two properly conducted tests.
d21770 In the IP this test method is atm the jurisdiction of the Standardization Committee. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The viscometer bath has a drain to remove the bath content. This coefficient is a measure of the resistance to flow of a liquid. Introduce sample through tube N taking care not to wet the sides of tube N, into the cross-arm D until the leading edge stands within 0.
Co 5 viscometer constant when filled and tested at the same temperature, T 5 temperature, F 5 temperature dependence factor see A3. If the sample is poured at a temperature above test temperature, wait 15 min for the sample in the viscometer to attain bath temperature and add more sample to overflow slightly into bulb K.
Results of this test method can be used to calculate viscosity when the density of the test material at the test temperature is known or can be determined. Practical 4 Effect of concentration on viscosity Name: 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. D — 95 Designation: The bath is fitted with a double window of which the front pane is detachable for cleaning purposes.
A hot storage stability test was carried out for polymer modified binder. The method is used to determine the consistency of bitumen as one element in establishing the uniformity of shipments or sources of supply.
Kinematic Viscosity ASTM D2170
Additionally the Cannon Instrument Co. 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. Box 16, State College, Pa. Two such determinations are needed from which to calculate a kinematic viscosity result that is the average of two acceptable determined d21770.

Historical Version s xstm view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: D viscometer calibration factor. Calibrated viscometers are available from a number of commercial suppliers.
Originally published as D — 63 T. Combining values from the two systems may result in non-conformance with the standard.
ASTM D / DM – 10 Standard Test Method for Kinematic Viscosity of Asphalts (Bitumens)
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. A bath overflow outlet protects from expanding bath oil when the bath filling is expanding at higher temperatures. The kinematic viscosity is then calculated by multiplying the efflux time in seconds by the 1 This test method is under the jurisdiction of ASTM Committee D-4 on Road and Paving Materials and is the direct responsibility of Subcommittee D Moreover, the results explained that the compatibility between PMMA and asphalt binder is improved upon further aging especially with low molecular weight polymer PMMA.
View as Grid List. On the Identification of Technology Shocks: A number in parentheses indicates the year of last reapproval.
It may be necessary to repack the ice around the thermometer because of melting. The kinematic viscosity characterizes flow behavior. Go to Wish List. Caution should be taken when handling asrm and mercury containing products. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.
Factors controlling heat exchange between the human body and its. Scientific Research An Academic Publisher. Rinse the ice with distilled water and x2170 or crush into small pieces, avoiding direct contact with the hands or any chemically unclean objects. 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.
Significance and Use 5. Last previous edition D — 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. 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 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. Measurement of viscosity of fluids. Summary of Test Method 4. It is commonly called the viscosity of the liquid.
See Annex A1 for the method of calculation. Remove the excess sample above filling mark G by inserting the special pipet until its cork rests on top of tube N; apply gentle suction until air is drawn through. The TV has a cover with three openings and lids.
