Why should you use a Tamson Viscosity bath to measure the kinematic viscosity of asphalts bitumens? Link to Active This link will always route to the current Active version of the standard. D21700 values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Details regarding calibration of viscometers are given in Annex A3. The constant ratio of the shearing stress to the rate of shear is the viscosity of the liquid. The values given in column 3 are the limits that should not be exceeded by the difference between the results of two properly conducted tests.
Physical and Chemical Properties. This coefficient is a measure of the resistance to flow of a liquid. Measurement of viscosity of fluids. Introduce sufficient sample through tube N to completely fill bulb D, overflowing slightly into overflow bulb K. The suggestions in the d170 sections of this appendix are given specifically for the mercury-in-glass kinematic viscosity thermometers and may not apply to other thermometers.
ASTM D2170/D2170M – 10
Since these thermometers are typically in a kinematic viscosity bath which has vision through the frontthe thermometer is read by lowering the thermometer such that the top of the mercury column is 5 to 15 mm below the surface of the bath liquid. A charge of the erythrocyte test by automated method. Add to Cart Add to Cart. The TV and TV have a bath volume of 20 and 40 litres respectively. If the reading is found to be higher or lower than the reading corresponding to a previous calibration, readings at all other temperatures will be correspondingly increased or decreased.
The morphological studies of polymer modified binder were discussed. Or visit our webshop to get price and technical information for a viscosity bath and accessories to determine the kinematic viscosity of asphalts bitumens conform to ASTM D and ISO Aztm Annex A1 for the method of calculation. Failure to correct for gravity can result in errors of 0.
Periodically clean the instrument 9. This standard has been approved for use by astn of the Department of Awtm. Calibrated viscometers are available from a number asstm commercial suppliers.
This error can be as much as one or two thermometer divisions.
In x2170 cases, however, follow the general procedure described in 8. Caution should be taken when handling mercury and mercury containing products. Show 9 15 The method is used to determine the consistency of bitumen as one element in establishing the uniformity of shipments or sources of supply. The bath is fitted with a double window of which the front pane is detachable for cleaning purposes.
Fill the Dewar vessel with the crushed ice and add sufficient distilled and preferably precooled water to form a slush, but not enough to float the ice. See Annex A1 for the method of calculation.
The viscometer bath has a drain to d21770 the bath content. Reverse-flow viscometers are used for the measurement of kinematic viscosities of opaque and transparent liquids up to cSt. Scientific Research An Academic Publisher. Be careful to ensure that the expansion chamber at the top of the thermometer is above the lid of the constant temperature bath.
The kinematic viscosity characterizes flow behavior. If the ratio is not constant, the liquid is non-Newtonian. Remove This Item Compare.
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Originally published as D — 63 T. Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version zstm Preparation of Sample 7.
ASTM D/DM – 10 – Standard Test Method for Kinematic Viscosity of Asphalts (Bitumens)
As the ice melts, drain off some of the water and add more crushed ice. Nonchromiumcontaining, strongly oxidizing acid cleaning solutions6 may be substituted so as to avoid the disposal problems of chromiumcontaining solutions.
Users should be aware that selling mercury, mercury containing products, d270 both, in your state may be prohibited by state law. The kinematic viscosity characterizes flow behavior. If the sample may contain lint, solid particles, etc.
ASTM D Standard
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.
B Based on less than 30 degrees of freedom. These factors are based on an average coefficient of expansion for asphalt cement of 0. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Mount the viscometer in the constant-temperature bath, keeping tube L vertical. It is commonly called the viscosity of the liquid.
