The basic experimental types in rheology are generally grouped into three categories: flow, oscillation, and transient tests. Each basic test group is introduced along with specific information to be gained from each test type and guidelines for appropriate experimental design. Emphasis is also paid to the complimentary nature of the test types, and how one might be used to extend the range of information obtained from another.
Flow
Steady state flow
Yield stress measurements

Part 3: Tips for Data Reduction and Presentation
IN THIS SESSION
As with any analytical technique, rheological data should be inspected carefully to avoid misinterpretation. Extreme experimental conditions can lead to errors. Strategies are introduced to show when such errors may be present, how the data can be used to show this, and how to mitigate the undesirable condition.
