Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The viscosity behavior measured after high shear is indicative of the characteristics of the paint soon after application. Performance Rotational viscometers cover a very wide measuring range. The higher the tested viscosity is, the stronger the spring has to be.

Historical Version s – view previous versions of standard Translated Version s: Link to Active This link will always route to the current Active version of the standard.

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 viscosity calculation is based on this assumption. A great number of standards is available for rotational viscometers, among them for example: Each viscometer model comes with a number of different measuring spindles. This website uses cookies to improve user experience.

Rotational viscometers are the widest spread viscometers on s2196 market and can be found in more or less all industries independent of company size. The values given in parentheses are for information only. Learn more about the Rotational Principle. Dynamic viscosity Learn more about the Rotational Principle. Results provide reasonable repeatabilty but the absolute precision is not reliable due to inadequate temperature precision.

Sample Typical sample volume for manual operation: One spindle is suitable only for a part of the model’s measuring range. The resulting wide gap between the bob and the vessel’s wall is assumed to be infinite.

The viscosity behavior measured after high shear is indicative of the characteristics of the paint soon after application. Rotational viscometers cover a very wide measuring range. 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. We offer typical values which are based on the values in brochures and standards but are not related to specific instruments.

The easy filling of a simple sample astn and the fast and easy exchange of the measuring bob make rotary viscometers the most qstm instruments, giving good results in various applications. 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 shear combination of Test Methods B and C. Rotational viscometers that test typically qstm of sample in an open beaker are in most cases operated without r2196 control.

The high-shear treatment in Test Method C approximates shearing during paint application.

With Test Methods B and C, the extent of shear thinning is indicated by the drop in viscosity with increasing viscometer speed. By using our website you consent to all cookies in accordance with our Cookie Policy.

For systems that use a spring for measuring the torque, there are different models designed for different viscosity ranges. Anton Paar has once again redefined digital density measurement with the groundbreaking invention of a new measuring principle: The listed specifications apply to a typical instrument with spring mechanics and a classic cylinder or disc spindle in a large sample vessel. Viscosity measuring range – for a model for medium viscosity materials, with several different spindles: The high-shear treatment in Test Method C approximates shearing during paint application.

Still, thermostat baths are available that can hold even a mL beaker. Density Redefined Anton Paar has once again redefined digital density measurement with the groundbreaking invention of a new measuring principle: Temperature control Rotational viscometers that test typically mL of sample in an open beaker are in most cases operated without temperature control. The values given in parentheses are for information only. 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.

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 typically used for quality control. Historical Version s – view previous versions of standard. 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.

Standards and Norms A great number of standards is available for rotational viscometers, among them for example: Tests are performed at ambient temperature.
