Successive readings taken at X1. Firm asmt for the viscometer shall be provided, or the viscometer may be an integral part of the bath. Mount the viscometer in the constant-temperature bath, keeping tube L vertical. Unlike the modified Ostwald and suspended-level viscometers, the sample of liquid flows into a timing bulb not previously wet by sample, thus allowing the timing of liquids whose thin films are opaque.

Discard any cloudy or unsound portions. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved e2170 withdrawn. Purchase orders should be addressed to the Cannon Instrument Co.

Summary of Test Method 4. The suggestions in the following sections of this appendix are given specifically for the mercury-in-glass kinematic viscosity thermometers and may not apply to other thermometers. Introduce sufficient sample through tube N to completely fill bulb D, overflowing slightly into overflow bulb K.


The kinematic viscosity characterizes flow behavior. The viscometer bath has a drain to remove the bath content. Co 5 viscometer constant when filled and tested at the same temperature, T 5 temperature, F 5 temperature dependence factor e2170 A3. See Annex A1 for the method of calculation.

ASTM D2170

Why should you use a Tamson Viscosity bath to measure the kinematic viscosity of asphalts bitumens? A superscript epsilon e indicates xstm editorial change since the last revision or reapproval. If the ratio is not constant, the liquid is non-Newtonian. It may be necessary to repack the ice around the thermometer because of melting.

The upper meniscus shall coincide with mark G. Go to D170 List. Practical 4 Effect of concentration on viscosity Name: Caution should be taken when handling mercury and mercury containing products.

ASTM D Standard

Originally published as D — 63 T. Results showed that the inclusion of PMMA polymer in asphalt binder has significantly improved its properties. Remove This Item Compare.

Results of this test method can be used to calculate viscosity when the density of the test material at the test temperature is known or can be determined. Determine the efflux time to the nearest 0.


If the sample is poured at a temperature above test temperature, wait 15 min for the sample in e2170 viscometer to attain bath temperature and add more sample to overflow slightly into bulb K. Show 9 15 Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Dry the viscometer by passing a slow stream of filtered, dry air through the viscometer for 2 min, or until the last trace of solvent is removed. Physical and Chemical Properties. Select also a standard viscometer of known C constant.

ASTM D / DM – 10 Standard Test Method for Kinematic Viscosity of Asphalts (Bitumens)

Current edition d21770 Oct. Certificates for viscometers should state the value of g at the location of the calibrating laboratory. If the sample may contain lint, solid particles, etc.

Thus, the accurate determination of viscosity is essential to many product specifications.
