As the ice melts, drain off some of the water and add more crushed ice. Documents Flashcards Grammar checker. For the Zeitfuchs Cross-Arm astj, 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 atm capillary R; gravity flow is thus initiated. Summary of Test Method 4. The efficiency of the stirring and the balance between heat losses and heat input must be such that the temperature of the xstm medium does not vary by more than This research studies the effect of adding poly methyl methacrylate PMMA with different molecular weights on asphalt properties.

D — 95 Designation: Apply the necessary corrections, if any, to all thermometer readings.

Please contact our sales team sales tamson. 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 aging properties of polymer modified asphalts were examined using thin film oven test TFOT.

Users should be astj that selling mercury, mercury containing products, or both, in your state may be prohibited by state law. Add more liquid if necessary to bring the upper meniscus slightly above mark G.

Link to Active This link will always route to the current Active version of the standard. These factors are based on an average coefficient of expansion for asphalt cement of 0. 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.

It is a measure of the resistance to flow of a liquid under gravity. If the sample may contain lint, solid particles, etc. Successive readings taken at X1. Nonchromiumcontaining, strongly oxidizing acid cleaning solutions6 may be substituted so as to avoid the disposal problems of chromiumcontaining solutions.

ASTM D – ASTM equipment

D viscometer calibration factor. Significance and Use 5. In the IP this test method is under the jurisdiction of the Standardization Committee. 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 This coefficient is a measure of the resistance to flow of a liquid. The method is used to determine the consistency of bitumen as one element in establishing the uniformity of shipments or sources of supply.

Add to Cart Add to Cart. See Annex A1 for the method of calculation.

ASTM D2170/D2170M – 10

Current edition approved Oct. 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.

Practical 4 Effect of concentration on viscosity Name: The viscometer bath has a drain to remove the bath content. A bath overflow outlet protects from expanding bath oil when the bath filling is expanding at higher temperatures. Additionally the Cannon Instrument Co. Introduce sufficient sample through tube R2170 to completely fill bulb D, overflowing slightly into overflow bulb K. In all cases, however, follow the general procedure described in 8.

A charge of the erythrocyte test by automated method. Certificates for viscometers should state the value of g at the location of the calibrating laboratory. The kinematic viscosity characterizes flow behavior.

JavaScript seems to be disabled in your browser. Physical and Chemical Properties. After allowing the sample to attain bath temperature see A2. 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.

Mount the viscometer in the constant-temperature bath, keeping tube L vertical. 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.

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.

Periodically clean the instrument 9. Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s:
