EUROLAB laboratory provides testing and compliance services within the scope of ASTM D2196 standard. The ASTM D2196 standard covers the determination of the apparent viscosity and shear thinning and thixotropic properties of non-Newtonian materials in the shear rate range of 600 s -0.1 to 1 s -50 using a 1 fluid rotary viscometer.
Test Method A is used to determine the apparent viscosity at a given rotational speed, but viscosities at two or more speeds provide better characterization of a non-Newtonian material than a single viscosity measurement.
With Test Methods B and C, the extent of shear thinning is indicated by the decrease in viscosity with increasing rotational speed. The degree of thixotropy is indicated by comparing viscosities at increasing and decreasing rotational speeds (Test Method B), viscosity recovery (Test Method B), or viscosities before and after high shear (combination of Test Methods B and C).
The high shear in Test Method C approaches shear during paint application. The viscosity behavior measured after high shear indicates the properties of the paint immediately after application.
Values stated in SI units should be accepted as standard. Values in parentheses are for informational purposes only.
This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.
Our organization, EUROLAB, provides rotational viscometer and standard test methods services for the rheological properties of non-Newtonian materials, within the framework of national and international standards, with its trained and expert staff and advanced technological equipment, among numerous test, measurement, analysis and evaluation studies. Provides testing services within the scope of ASTM D2196 standard.
