For safety reasons the tap can only be opened by using a screwdriver. The viscosity in Pascal-seconds is calculated by multiplying the flow time in seconds by the viscometer calibration factor. The average in table 2 is taken from the five other samples. To use this website, you must agree to our Privacy Policyincluding cookie policy. In the picture, qstm can see an example of our TV cover. Optional is a three decimal readout. Published by Robert Sharp Modified over 2 years ago. In Europe it is named bitumen, while in North America it is named asphalt cement or asphalt.

Flow rate is mass flow rate i. Cover of TV offers seven holes eight optional. The deviation is calculated by dividing the v by the average of the five samples. To make this website work, we log user data and share it with processors. If you wish to download it, please recommend it to your friends in any social system.

Cover of TV offers three holes four optional. Remove bath from packaging material. It is applicable to materials having viscosities in the range from 0. Share buttons are a little bit lower. Flow times between and seconds are recommended.


Function Delivers user specified flow rate of gas. These openings accommodate glass vacuum capillary viscometers in viscometer holders. Users should be aware that selling mercury, mercury-containing products, or both, in your state may be asym by state law. Prevent the holders from shifting position when, for example, silicon tubing is connected to the viscometers in order to apply vacuum.

Tamson TV4000 for ASTM D2171 Viscosity of Bitumen

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. Breakage of the glass viscometers can easily happen with the rubber and plastic holders available on the market currently.

The viscosity bath is fitted with a double window of which the front pane is detachable for cleaning purposes. Hydrocarbon product, originating from crude oil, refrained from lighter fractions. The results of the six tests are mentioned in the table.

The apparent viscosity for non-Newtonian asphalt binders varies with shear rate. A manual viscosity bath is asrm for the measurement of bitumen. All other variables stay the same. It is applicable to materials having viscosities in the range from 0.

Refined it is a stable, semi-solid substance, at ambient temperatures. Historical Version s – view previous versions r2171 standard Work Item s – proposed revisions of this standard Translated Version s: And the deviation in the measuring result is Viscometer holders also have a cover consisting of the layers.

ASTM D Standard

The four supporting feet can be turned in and outwards for exact adjustment. New design and electronics since Four stages are available: Clean inner bath thoroughly of any loose packing materials, etc. In every continent and most of the atsm worldwide you can find a TV or TV The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

The standard describes the manual measuring of determination of kinematic asttm.

ASTM D & IP – ASTM equipment

Modified asphalt binders or asphalt binders that have been conditioned or recovered are typically non-Newtonian under the conditions of this test. Some competitors just state the standard deviation d1271 the mean or mention the stability for a few minutes.

Tamson can guarantee that the viscometer in its stainless steel holder is aligned at a 90 degree angle to the cover as prescribed in ASTM D kinematic viscosity is determined using gravity. Auth with social network: The viscosity bath has a drain to remove the bath content.
