Dynamic viscosity Learn more about the Rotational Principle. With Test Methods B and C, the extent of shear thinning is indicated by the drop in viscosity with increasing viscometer speed.

The higher the tested viscosity is, the stronger the spring has to be.

The degree of thixotropy is indicated by comparison of viscosities at increasing and decreasing viscometer speeds Test Method Bviscosity recovery Test Method Bor viscosities before and after high d21966 combination of Test Methods B and C.

The easy filling of a simple sample container and the fast and easy exchange of the measuring bob make rotary viscometers the most versatile instruments, giving good results in various applications.

Tests are performed at ambient temperature. A great number of standards is available for rotational viscometers, among them for example: The values given in parentheses are for information only. ast,

The viscosity calculation is based on this assumption. Standards and Norms A great number of standards is available for rotational viscometers, among them v2196 example: Anton Paar has once again redefined digital density measurement with the groundbreaking invention of a new measuring principle: Still, thermostat baths are available that can hold even a mL beaker.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Rotational viscometers that test typically mL of sample in an open beaker are in most cases operated without temperature control.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Viscosity measuring range – for a model for medium viscosity materials, with several different spindles: The listed specifications apply to a typical instrument with spring mechanics and a classic cylinder or disc spindle in a large sample vessel.

Sample Typical sample volume for manual operation: Results provide reasonable repeatabilty but the absolute precision is not reliable due to inadequate temperature precision.

ASTM D, Test equipment Controls

Rotational viscometers cover a very wide measuring range. In addition, there are special sample adapters available for reducing the required sample volume, for extending the measuring range and for a wider temperature range. The viscosity behavior measured after high shear is indicative of the characteristics of the paint soon after application. The viscosity behavior measured after high shear is indicative of the characteristics of the paint soon after application.

The qstm wide gap between the bob and the vessel’s wall is assumed to be infinite. This website uses cookies to improve user experience. For systems that use a spring for measuring the torque, there are different models designed for different viscosity ranges.

Each viscometer model comes with a number of different measuring spindles. The high-shear treatment in Test Method C approximates shearing during paint application.

ASTM D2196-18e1

Test Method A is used for determining the apparent viscosity at a given rotational speed, although viscosities at two or more speeds give better characterization of a non-Newtonian material than does a single viscosity measurement.

Rotational viscometers are the widest spread viscometers on the market and can be found in more or less all industries independent of company size. The degree of thixotropy is indicated by comparison of viscosities at increasing and decreasing rotational speeds Test Method Bviscosity recovery Test Method Bor viscosities before and after high shear combination of Test Methods B and C. The high-shear treatment in Test Method D296 approximates shearing during paint application.
