Prevent the holders from shifting position when, for example, silicon tubing is connected to the viscometers in order to apply vacuum. ASTM D prescribes reverse flow viscometers. Link to Active This link will always route to the current Active version of the standard. This way the temperature reading on the display can be synchronised with an independent separate thermometer. Breakage of the glass viscometers can easily happen with the rubber and plastic holders available on the market currently.

The time is measured for a fixed volume of the liquid to be drawn up through a capillary tube by means of vacuum, under closely controlled conditions of vacuum and temperature inside a viscosity bath. The average in table 2 is taken from the five other samples.

For this reason the overflow outlet must be connected to a waste container. This is possible with the special design of the covers used in the Tamson viscosity baths and the Tamson stainless steel viscometer holders.

ASTM D & IP – ASTM equipment

This is a good explanation as to why the bath temperature is not stable. Place the bath spirit level.

Substitute for the commonly known mercury thermometers Free Tamcom software Range from In the picture, you can see an example of our TV cover. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Row 2 gives the duration of a measurement in seconds, where the time is measured via two optical infra red sensors.


It is also very important that the bath temperature is as stable as d217 in order to adtm the most accurate results. Refined it is a stable, semi-solid substance, at ambient temperatures.

Therefore, we show a two decimal readout in the display. To make this website work, we log user data and share it with processors. Share buttons are a little bit lower.

When the flow is non-Newtonian in a capillary tube, the shear rate determined using this test method may be invalid. These are available for most viscometers, please see WWW.

A manual viscosity bath is used for the measurement of bitumen. When connecting to tap water or an external cooler, sub ambient temperatures can be reached. Zstm standard describes the manual measuring of determination of dynamic viscosity. Sample 2 Time [sec. Historical Version s – view previous versions of standard.

Viscosity of Bitumen ASTM D2170, EN 12595, ASTM D2171, IP 222, EN 12596, AASHTOT 202 Rev 1.01.

With the additional 0. The results of the six tests are mentioned in the table. If you wish to download it, please recommend it to your friends in any social system. The viscosity in Pascal-seconds is calculated by asstm the flow time in seconds by the viscometer calibration factor. Work Item s – proposed revisions of this standard.

ASTM D2171

It is highly energy efficient 6 Watts. The insulated d21171 makes it easy and safer to remove the viscometer even at high working temperatures. Remove bath from packaging material. The delta in temperature is Since introduction, thousands installed.

ASTM D Standard

For the best experience on our site, be sure to turn on Javascript in your browser. The presence of non-Newtonian behavior for the test conditions of this test can be verified by measuring the viscosity with viscometers having different-sized capillary tubes or with different pressure heads.


This is very important when temp is e. Show 9 15 Therefore, accurate viscosity analysis of bitumen at different temperatures has become an important test. Reliable results depend on many factors; following the suggestions of Specification D or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.

Agencies that meet the criteria of Specification D are generally considered capable of competent and objective testing, sampling, inspection, etc.

View as Grid List. Published by Robert Sharp Modified over 2 years ago. Row 5 demonstrates the difference between the maximum and minimum temperature. This circuit board offers several nice features: Caution should be taken when xstm mercury and mercury-containing products.

By using the RS communication port, the controller can be d21711 remotely using the Tamson software, or a serial terminal, or your own software. About project SlidePlayer Terms of Service.

COM for further information. Row 6 gives the average temperature of the bath during a test. Test Method D may be a more applicable method for testing non-Newtonian asphalts. So, fault of Tamson timer when measuring one hour is three times less than human error atsm flow time is between and seconds.

Cover of TV offers three holes four optional. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
