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.

ASTM D2171

All other variables stay the same. This is possible with the special design of the covers used in the Tamson viscosity baths and ast Tamson stainless steel viscometer holders.

This is a good explanation as to why the bath temperature is not stable. Flow times between and seconds are recommended. The viscometer has to be suspended in a vertical position. It is applicable to materials having viscosities in the range from 0. A bath overflow outlet protects from expanding bath oil when the bath filling is expanding at higher temperatures. Registration Forgot your password? Two such determinations are needed from d1271 to calculate a kinematic viscosity result that is the average of two acceptable determined.

ASTM D prescribes reverse flow viscometers. Add to Cart Add to Cart.

School of Mechatronics Gwangju. In Europe it is named bitumen, while in North America it is named asphalt cement or asphalt. Caution should be taken when handling mercury and mercury-containing products. Test Method D may be a more applicable method for testing non-Newtonian asphalts.


Optional is a three decimal readout. 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Tamson stainless steel holders will wstm into the openings of the covers axtm in our viscosity baths perfectly.

Clean inner bath thoroughly of any loose packing materials, etc. A manual viscosity bath is used for the measurement of bitumen. The insulated handle makes it easy and safer to remove the viscometer even at high working temperatures. The standard describes the manual measuring of determination of kinematic viscosity.

The apparent viscosity for non-Newtonian asphalt binders varies with shear rate.

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

If you wish to download it, please recommend it to your friends in any social system. Prevent the d271 from shifting position when, for example, silicon tubing is connected to the viscometers in order to apply vacuum. Cover of TV offers three holes four optional. Sample 2 Time [sec. New design and electronics s2171 Row 5 demonstrates the difference between the maximum and minimum temperature. Agencies that meet the criteria of Specification D are generally considered capable of competent and objective testing, sampling, inspection, etc.

But what is the consequence for the viscosity result if the bath temperature is varying by 0.


Dominant standard in petrochemical labs. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.

When connecting to tap water or an external cooler, sub ambient temperatures can be reached. 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.

Substitute for the commonly known mercury thermometers Free Tamcom software Range from d1271 To use this website, you must agree to our Privacy Policyincluding cookie policy. Row 2 gives the duration of a measurement in seconds, where the time is measured via two optical infra red sensors.

Some competitors just state the standard deviation of the mean or mention the stability for a few minutes. JavaScript seems to be disabled in your browser. This way the temperature reading on the display can be synchronised with an independent separate thermometer. These openings accommodate glass vacuum capillary viscometers in viscometer holders. By using the RS communication port, the controller can be controlled remotely using the Tamson software, or a serial terminal, or your own software.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
