The TV viscosity bath has a cover with seven openings and lids. Combining values from the two systems may result aetm nonconformance with the standard.
In every continent and most of the countries worldwide you can find a TV or TV About project SlidePlayer Terms of Service.
Tamson stainless steel holders will fit into the e2171 of the covers used in our viscosity baths perfectly. The viscosity in Pascal-seconds is calculated by multiplying the flow time asym seconds by the viscometer calibration factor. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
This is very important when temp is e. Based on this experiment, we can conclude that a slight temperature variation by only 0.
The standard describes the manual measuring of determination of kinematic viscosity. Historical Version s – view previous versions of standard. So, fault of Tamson timer when measuring one hour is three times less than human error viscosity flow time is between and seconds.
Viscosity of Bitumen ASTM D2170, EN 12595, ASTM D2171, IP 222, EN 12596, AASHTOT 202 Rev 1.01.
The insulated handle makes it easy and safer to remove the viscometer even at high working temperatures. Cover of TV offers seven holes eight optional. Optional is a three decimal readout. To make this website work, we log user data and share it with processors. Sample 2 Time [sec. The viscosity bath is fitted with a double window of which the front pane is detachable for cleaning purposes.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. A bath overflow outlet protects from expanding bath oil d21171 the bath filling is expanding at higher temperatures. View as Grid List.
Caution should be taken when handling mercury and mercury-containing products. For safety reasons the tap can only be opened by using a screwdriver.
Tamson TV for ASTM D Viscosity of Bitumen | DC Scientific
The viscometer has to be suspended in a vertical position. It is highly energy efficient 6 Watts. The four supporting feet can be turned in and outwards for exact adjustment. Remove bath from packaging material. School of Mechatronics Gwangju. My presentations Profile Feedback Log out. Another advantage of the Tamson holder is the clamp at the bottom of the holder, which makes it impossible for the viscometer to fall out of the holder.
The time is measured for a fixed volume of the liquid to be drawn up through a capillary tube by means ast vacuum, under closely controlled conditions of vacuum and temperature inside a viscosity bath.
Modified asphalt binders or asphalt binders that have been conditioned or recovered are typically non-Newtonian under the conditions of this test. These are available for most viscometers, please see WWW. This way the temperature reading on the display can be synchronised with an independent separate thermometer.
Use a mains supply that is well earthed and clean of interference and can carry the load of the bath. The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used.
New design and electronics since Function Delivers user specified flow rate of gas. Go to Wish List.
The bottom layer has the standardized 51 mm openings as prescribed by ASTM D and related methods and the upper layer has wider openings to accommodate our stainless steel holders. These notes and footnotes excluding those in tables and figures shall not be considered awtm requirements of the standard.
Viscometer tubes will not move due to the bath fluid circulating inside the viscosity bath. When the flow is non-Newtonian in a capillary tube, the shear rate determined using this test method may be invalid.
The standard describes the manual measuring of determination of dynamic d22171. In the picture, you can see an example of our TV cover.
