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. In the IP this test method is under the jurisdiction of the Standardization Committee. Wipe excess sample off tube N and invert the viscometer to its normal position. Details regarding calibration astmm viscometers are given in Annex A3. Practical 4 Effect of concentration on viscosity Name: Increasing traffic loading and volumes on roads have led to the use of polymer modified binders to improve the performance of bitumen in terms of strength, durability, and resistance to rutting.
If asrm efflux time is less than 60 s, select a viscometer of smaller capillary diameter and repeat the operation.
Results showed that the inclusion of PMMA polymer in asphalt binder has significantly improved its properties. After allowing the sample to attain bath temperature see A2. Link to Active This link will always route to the current Active version of the standard.
Kinematic Viscosity ASTM D2170
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.
Add to Cart Add to Cart. The method is used to determine the consistency of bitumen as one element in establishing the uniformity of shipments or sources of supply. The kinematic viscosity determined value is the product of the measured flow time and the calibration constant of the viscometer.
Add more liquid if necessary to bring the upper meniscus slightly above mark G. The kinematic viscosity characterizes flow behavior. If the sample may x2170 lint, solid particles, etc. It is commonly called the viscosity of the liquid.
Failure to correct for gravity can result in errors of 0. View as Grid List.
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 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.
This density value is equivalent to a specific gravity of 1. The constant ratio of the shearing stress to the rate of shear is the viscosity of the liquid. Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: Nonchromiumcontaining, strongly oxidizing acid cleaning solutions6 may be substituted so as to avoid the disposal problems of chromiumcontaining solutions.
Certificates for viscometers should state the value of g at the location of the calibrating laboratory. Originally published as D — 63 T. It is recommended that the interval of checking be every six months; for a new thermometer, check monthly for the first six months.
Physical and Chemical Properties. Additionally the Cannon Instrument Co. 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.
ASTM D/DM – 10 – Standard Test Method for Kinematic Viscosity of Asphalts (Bitumens)
If the sample is poured at astj 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. 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.
Moreover, ashm results explained that the compatibility between PMMA and asphalt binder is improved upon further aging especially with low molecular weight polymer PMMA. The morphological studies of polymer modified binder were discussed. Periodically clean the instrument 9. Material and Type Index Single-operator precision: This coefficient is a measure of the resistance to flow of a liquid.
When thermometers are completely submerged, corrections for each individual thermometer based on calibration under conditions of complete submergence must be determined and applied.
Draw liquid through tube N, filling bulb D to fill mark G.
The time is measured for a fixed ashm 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.
Remove the excess sample above filling mark G by inserting the special pipet until its cork rests on asttm of tube N; apply gentle suction astn air is drawn through. 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.
See Annex A1 for the method of calculation. Two such determinations are needed from which to calculate a kinematic viscosity result that is the average of two acceptable determined values. 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.
Factors controlling heat c2170 between the human body and its.
As the ice melts, drain off some of the water and add more crushed ice. The TV and TV have a bath volume of 20 and 40 litres respectively. These factors are based on an average coefficient of expansion for asphalt cement of 0. B Based on less than 30 degrees of freedom. It may be necessary to repack the ice around the thermometer because of melting.
Firm supports for the viscometer shall be provided, or the viscometer may be an integral part of the bath.
