It is recommended that the interval of checking be every six months; for a new thermometer, check monthly for the first six months. As the ice melts, drain off some of the water and add more crushed ice. The kinematic viscosity range is based on a s minimum flow-time in this method; the same viscometers are also described in Specifications D with a different viscosity range based on a s minimum flow-time as prescribed in Test Method D 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.
These factors are based on an average coefficient of expansion for asphalt cement of 0. Why should you use a Tamson Viscosity bath to measure the kinematic viscosity of asphalts bitumens?
The use of similar commercially available sulphuric acid cleaning solutions is acceptable. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. It is the responsibility of the user of asmt standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
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. Combining values from the two systems may result in non-conformance with the standard. Successive readings taken at X1.
Additionally the Cannon V2170 Co. 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.
Such heating should not exceed 30 min.
Kinematic Viscosity ASTM D
The ice point reading shall be expressed to the nearest 0. Factors controlling heat exchange between the human body and its.
Select also a standard viscometer of known C constant. Work Item s – proposed revisions of this standard.
ASTM D/DM – 10 – Standard Test Method for Kinematic Viscosity of Asphalts (Bitumens)
Draw liquid through tube N, filling bulb D to fill mark G. The TV has a cover with three openings and lids. Shipment will be made as specified or by best means. In all cases, however, follow the general procedure described in 8. Significance and Use 5. Calibrated viscometers are available from a number of commercial suppliers.
The kinematic viscosity characterizes flow behavior. It is commonly called the viscosity of aatm liquid. Thus, the accurate determination of viscosity is essential to many product specifications.
Kinematic Viscosity ASTM D2170
Introduce sufficient sample through tube N to completely fill bulb Aztm, overflowing slightly into overflow bulb K. The viscometer bath has a drain to remove the bath content.
The suggestions in the following sections of this appendix are given specifically for the mercury-in-glass kinematic viscosity thermometers and may not apply to other thermometers. Summary of Test Method 4.
ASTM D2170/D2170M – 10
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. The TV and TV have a bath volume of 20 and 40 litres respectively. MS Word file of most equations that come up in Physics If the sample may contain lint, solid particles, etc.
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.
