The listed specifications apply to a typical instrument with spring mechanics and a classic cylinder or disc spindle in a large sample vessel.

The resulting wide gap between the bob and the vessel’s wall is assumed to be infinite. Results provide reasonable repeatabilty but the absolute precision is not reliable due to inadequate temperature precision.

ASTM D2196-18e1

Rotational viscometers are the widest spread viscometers on the market and can be found in more or less all industries independent of company size. Rotational viscometers cover a very wide measuring range. Tests are performed at ambient temperature. A great number of standards is available for rotational viscometers, among ast for example: The values given in parentheses are for information only. The viscosity calculation is based on this assumption.

Standards and Norms A great number of standards is available for rotational viscometers, among them for example: For systems that use a spring for measuring the torque, there are different models designed for different viscosity ranges.

Density Redefined 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.

With Test Methods B and C, the extent of shear thinning is indicated by the drop in viscosity with increasing viscometer speed. Learn more about the Rotational Principle. Rotational s2196 are typically used for quality control. Historical Version s – view previous versions of standard. Dynamic viscosity Learn more about the Rotational Principle. The high-shear treatment in Test Method C approximates shearing during paint asstm. Each viscometer model comes with a number of different measuring spindles.

One spindle is suitable only for a part of the model’s measuring range.

The viscosity behavior measured after high shear is indicative of the characteristics of the paint soon after application. Historical Version s – view previous versions of standard Translated Version s: The values given in parentheses are for information only. The viscosity behavior measured after high shear is indicative of the characteristics of the paint soon after application.

In addition, there are special sample adapters available for reducing xstm required sample volume, for extending the measuring range and for a wider temperature range. Sample Typical sample volume for manual operation: Viscosity measuring range – for a model for medium viscosity materials, with several different spindles: 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. Performance Rotational viscometers cover a very wide measuring range. 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.

The higher the tested viscosity is, the stronger the spring has to be. Rotational viscometers that test typically mL of sample in an open beaker are in most cases operated without temperature control. Anton Paar has once again redefined digital density measurement with the groundbreaking invention of a new measuring principle: The high-shear treatment in Test Method Asym approximates shearing during paint application. 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.

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

We offer typical values which d196 based on the values in brochures and standards but are not related to specific instruments. It is the responsibility of the user of this standard to establish appropriate safety, asm, and environmental practices and determine the applicability of regulatory limitations prior to use.
