Two such determinations are needed from which to calculate a kinematic viscosity result that is the average of two acceptable determined values. Failure to correct for gravity can result in errors of 0. Details regarding calibration of viscometers are given in Annex A3.
In all cases, however, follow the general procedure described in 8. The morphological studies of polymer modified binder were discussed. Draw liquid through tube N, filling bulb D to fill mark G. Or visit our webshop to ashm price and technical information for a viscosity bath and accessories to determine the kinematic viscosity of asphalts bitumens conform to ASTM D and ISO Successive readings taken at X1. Additionally the Cannon Instrument Co.
Reverse-flow viscometers are used for the measurement of kinematic viscosities of opaque and transparent liquids up to cSt.
ASTM D / DM – 10 Standard Test Method for Kinematic Viscosity of Asphalts (Bitumens)
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. Dry the tube by aastm a slow stream of filtered dried air through the capillary for 2 min, or until the last trace of solvent is removed. Users should be aware that selling mercury, mercury containing products, or both, in your state may be prohibited by state law.
It is the responsibility of the user of this standard e2170 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The kinematic viscosity determined value is the product of the measured flow time and the calibration constant of the viscometer. Calibrated viscometers are available from a number of commercial suppliers.
It is a measure of the resistance to flow of a liquid under gravity. A charge of the erythrocyte test by automated method. The practice of completely submerging astn thermometer is not recommended. These factors are based on an average coefficient of expansion for asym cement of 0. Kinematic viscosity, cSt 5 Ct 1 where: 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 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. The time is measured for a fixed volume of liquid to flow under gravity through x2170 capillary of a calibrated viscometer under a reproducible driving head and at a closely controlled and known temperature inside a viscosity bath. 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 asgm into bulb K.
This density value is equivalent to a specific gravity of 1. Purchase orders should be d1270 to the Cannon Instrument Co. Apply the necessary corrections, if any, to all thermometer readings. The TV has a cover with seven openings and lids.
The aging properties of polymer modified asphalts were examined using thin film oven test TFOT. Determine the efflux time d2107 the nearest 0. Preparation of Sample 7.
HaggamIsmail M. As the ice melts, drain off some of the water and add more crushed ice.
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.
ASTM D – 01a Standard Test Method for Kinematic Viscosity of Asphalts (Bitumens)
Caution should be taken when handling mercury and mercury containing products. Show 9 15 Indirect tensile strength ITS test and durability performance of modified asphalts were evaluated using Marshall Test. Shipment will be made as specified or by best means. 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. Measurement of viscosity of fluids.
A number in parentheses indicates the year of last reapproval. The TV has a cover with three openings and lids.
The efficiency of the stirring and the balance between heat losses and heat input must be such that the temperature of the bath medium does not vary by more than Abd ElrhmanSanaa A. If the test temperature differs from the fill temperature, the viscometer constant is calculated as follows: A superscript epsilon e indicates an editorial change since the last revision or reapproval. Scientific Research An Academic Publisher. Work Item s – proposed revisions of this standard.
