It is applicable to materials having viscosities in the range from 0. Some competitors just state the standard deviation of the mean or mention the stability for a few minutes.

ASTM D – 07 Standard Test Method for Viscosity of Asphalts by Vacuum Capillary Viscometer

ASTM D prescribes reverse flow viscometers. Feedback Privacy Policy Feedback.

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.

All other variables stay the same.

Referenced Documents purchase separately The documents listed below are d217 within the subject standard but are not provided as part of the standard. Agencies that meet the criteria of Specification D are generally considered capable of competent and objective testing, sampling, inspection, etc. This maximum power can be selected to prevent overshoot or burning of bath media.

Outside window pane can be removed by unscrewing the four black screws which is very easy. The apparent viscosity for non-Newtonian asphalt binders varies with shear rate.

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.

In the picture, you can see an example of our TV asym. Viscometer tubes will not move due to the bath fluid circulating inside the viscosity bath. Viscosity grade of bitumen have a thermoplastic property which causes the material to become liquid at high temperatures and to harden at ambient temperatures.

Tamson TV for ASTM D Viscosity of Bitumen | DC Scientific

Use a mains supply that is well earthed and clean of interference and can carry the load of the bath. Why is astj viscosity of asphalts bitumens important to know? Two such determinations are needed from which to calculate a kinematic viscosity result that is the average of two acceptable determined. Share buttons are a little bit lower.

It is highly energy efficient 6 Watts. As an example, we show below a graph off an unstable bath.

Remove This Item Compare. View as Grid List. Prevent the holders from shifting position when, for example, silicon tubing is connected to the viscometers in order to apply vacuum. Users should be aware that selling mercury, mercury-containing products, or both, in your state may be prohibited by state law. The viscosity in Pascal-seconds is calculated by multiplying the flow time in seconds by the viscometer calibration factor.

With the additional 0. Row 6 gives the average temperature of the bath during a test. The insulated handle makes it easy and safer to remove the aatm even at high working temperatures.

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. Place the bath spirit level. Breakage of the glass viscometers asmt easily happen with the rubber and plastic holders available on the market currently.

ASTM D2171

Cover of TV offers three holes four optional. OK Classification of Instruments:. The results of the six tests are mentioned in the table. This is possible with the special design of the covers used in the Tamson viscosity baths and the Tamson stainless steel viscometer holders. Viscometer holders also have a cover consisting of the layers. This is very important when temp is e.

If necessary, the PID settings can be manually adjusted to get the best optimum.

Tamson stainless steel holders will fit into the openings of the covers used in our viscosity baths perfectly. ASTM D prescribes vacuum viscometers. It is applicable to materials having viscosities zstm the range from 0.
