Viscosity grade of bitumen have a thermoplastic property which causes dd2171 material to become liquid at high temperatures and to harden at ambient temperatures. 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.

New design and electronics since Go to Wish List. As an example, we show below a graph off an unstable bath. Substitute for the commonly known mercury thermometers Free Tamcom software Range from Row 5 demonstrates the difference between the maximum and minimum temperature.

Link to Active This link will always route to the current Active version of the standard. The TV viscosity bath has a cover with seven openings and lids. Mercury, or its vapor, may be hazardous to health and corrosive to materials. If you wish to download it, please recommend it to your friends in any social system.

Optional is a three decimal readout. We think you have liked this presentation. The value is displayed with a resolution of 0. A bath overflow outlet protects from expanding bath oil when the bath filling is expanding at higher temperatures.

Four stages are available: For safety reasons the tap can only be opened by using a screwdriver. Auth with social network: Outside window pane can be removed by unscrewing the four black screws which is very easy. Registration Forgot your password? ASTM D prescribes reverse flow viscometers. The apparent viscosity for non-Newtonian asphalt binders varies with shear rate. Please contact our sales team sales tamson. Therefore, we show a two decimal readout in the display.

ASTM D – 01 Standard Test Method for Viscosity of Asphalts by Vacuum Capillary Viscometer

With the additional 0. Viscometer tubes will not move due to the bath fluid circulating inside the viscosity bath. Refined it is a stable, semi-solid substance, at ambient temperatures.

Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: The time is measured for a fixed volume of liquid to flow under gravity through the capillary of a calibrated reverse flow viscometer at a closely controlled and known temperature. Therefore, accurate viscosity analysis of bitumen at different temperatures has become an important test. When the flow is non-Newtonian in a capillary tube, the shear rate determined using this test method may be invalid.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Users should be aware that selling mercury, mercury-containing products, or both, in your state may be prohibited by state law. This is possible with the special design of the covers used in the Tamson viscosity baths and the Tamson stainless steel viscometer holders.

The deviation is calculated by dividing the v by the average of the five samples. Since introduction, thousands installed. COM for further information. The viscosity bath has a drain to remove the bath content. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Modified asphalt binders or asphalt binders that have been conditioned or recovered are typically non-Newtonian under the conditions of this test. Combining values from the two systems may result in nonconformance with the standard.

This maximum power can be selected to prevent overshoot or burning of bath media. The defined precision limits in Section 11 may not be applicable to non-Newtonian asphalt binders.

Tamson TV4000 for ASTM D2171 Viscosity of Bitumen

Use a mains supply that is well earthed and clean of interference and can carry the load of the bath. When connecting to tap water or an external cooler, sub ambient temperatures can be reached. Flow rate is mass flow rate i. Cover of TV offers seven holes eight optional. Function Delivers user specified flow rate of gas. The viscosity bath is fitted with a double window of which the front pane is detachable for cleaning purposes.

Breakage of the glass viscometers can easily happen with the rubber and plastic holders available on the market currently. The viscosity in Pascal-seconds is calculated by multiplying the flow time astn seconds by the viscometer calibration d22171. Prevent the holders from shifting position when, for example, silicon tubing is connected to the viscometers in order to apply vacuum.

The standard describes the manual measuring of determination of kinematic viscosity. It is highly energy efficient 6 Watts. These openings accommodate glass vacuum capillary viscometers in viscometer holders.
