Users of this standard are cautioned that compliance with Specification D alone does not completely ensure reliable results. Flow times between and seconds are recommended.

It is highly energy efficient 6 Watts. Dominant standard in petrochemical labs. Remove bath from packaging material. So, fault of Tamson timer when measuring one hour is three times less than human error viscosity flow time is between and seconds. ASTM D prescribes vacuum viscometers. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ASTM D prescribes reverse flow viscometers.

ASTM D Standard

Work Item s – proposed revisions of this standard. The defined precision limits in Section 11 may not be applicable to non-Newtonian asrm binders. Therefore, accurate viscosity analysis of bitumen at different temperatures has become an important test. Some competitors just state the standard deviation of the mean or mention the stability for a few minutes.


The Tamson stainless steel holders are widely used and popular among users due to a robust design. This is very important when temp is e.

These are available for most viscometers, please see WWW. JavaScript seems aztm be disabled in your browser. Auth with social network: This is possible with the special design of the covers used in the Tamson viscosity baths and the Tamson stainless steel viscometer holders. Two such determinations are needed from which to calculate a kinematic viscosity result that is the average of two acceptable determined.

Mercury, or its vapor, may be hazardous to health and corrosive to materials. Cover of TV offers seven holes eight optional. Astk delta in temperature is Outside window pane can be removed by unscrewing the four black screws which is very easy.

ASTM D2171

Please contact our sales team sales tamson. The standard describes the manual measuring of determination of kinematic viscosity. Clean inner bath thoroughly of any loose packing materials, etc. The kinematic viscosity determined value is the product of the measured flow time and the calibration constant of the viscometer. Caution should be taken when handling mercury and mercury-containing products. Place the bath spirit level. About project SlidePlayer Terms of Service. Users should be aware that selling mercury, mercury-containing f2171, or both, in your state may be prohibited by state law.


New design and electronics since The value is displayed with a resolution of 0.

It atm also very important that the bath temperature is as stable as possible in order to get the most accurate results. Optional is a three decimal readout.

Tamson TV4000 for ASTM D2171 Viscosity of Bitumen

Refined it is a stable, semi-solid substance, at ambient temperatures. Reliable results depend on many factors; following the suggestions aastm Specification D or some similar acceptable guideline provides a means of evaluating and controlling some of those factors. This is a good explanation as to why the bath temperature is not stable. In the picture, you can see an example of our TV cover.

For safety reasons the awtm can only be opened by using a screwdriver. Published by Robert Sharp Modified over 2 years ago. View as Grid List.

Show 9 15 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 asm holders. The viscosity in Pascal-seconds is calculated by multiplying the flow time in seconds by the viscometer calibration factor.
