Dominant standard in petrochemical labs. Sample 2 Time [sec. The deviation is calculated by dividing the v by the average of the five samples.
These are available for most viscometers, please see WWW. Cover of TV offers seven holes eight optional. The Tamson stainless steel holders are widely used and popular among users due to a robust design.
Prevent the holders from shifting position when, for example, silicon tubing is c2171 to the viscometers in order to apply vacuum.
ASTM D prescribes vacuum viscometers. Viscometer holders also have a cover consisting of the layers. Flow times between and seconds are recommended.
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. Link to D2711 This link will always route to the current Active version of the standard. Test Method D may be a more applicable method for testing non-Newtonian d21711. View as Grid List. 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 bath has to be filled with a liquid suitable for operating temperature.
This is very important when temp is e. The viscosity bath is fitted with a double window of which the front pane is detachable for cleaning purposes. It is applicable to materials having viscosities in the range from 0. The TV viscosity bath has a cover with seven openings and lids.

Some competitors just state the standard deviation of the mean or mention the stability for a few minutes.
Mercury, or its vapor, may be hazardous to health and corrosive to materials. A manual viscosity bath is used for the measurement of bitumen.
Row 5 demonstrates the difference between the maximum and minimum temperature. These openings accommodate glass vacuum capillary viscometers in viscometer holders. And the deviation in the measuring result is
